Aharrypotter 4ac2a9acd8 bench: report when a foreign vendor's FlagGems implementation gets loaded 
FlagGems keeps per-vendor implementations under
flag_gems/runtime/backend/_<vendor>/ops/, and benchmarks commonly gate on
whether one imports:

    try:
        from flag_gems.runtime.backend._nvidia.hopper.ops.mm import router_gemm
        ROUTER_GEMM_AVAILABLE = True
    except Exception:
        ROUTER_GEMM_AVAILABLE = False

An import only proves the .py is on disk. It touches no device, so it succeeds
on every backend and the gate never fires. test_router_gemm.py therefore ran
the NVIDIA Hopper kernel on an S5000: its autotune and heuristics are keyed to
nvidia, supply no BLOCK_M/N/K/SPLIT_K on musa, and the run died deep inside the
JIT with "dynamic_func() missing 4 required positional arguments" — an error
that points nowhere near the cause. Meanwhile _mthreads/ops/mm.py holds a
working router_gemm the benchmark never imports. Gating on vendor_name first,
the way the Cambricon branch in the same file already does, makes it run: 10
shapes, 10 kernels, cvt 10 -> 2.

The plugin now scans sys.modules at session end and prints
FOREIGN_VENDOR_MODULE with the vendors it found. It reports rather than
refuses: loading another vendor's module is not proof of a problem, but when a
result looks wrong it is the first line to check. Vendor roots are compared
segment-wise, not by prefix, so a vendor whose name extends ours is not
mistaken for our own.

README gains the ordered checklist for an operator that will not run, with the
real instance behind each entry.

Aharrypotter 2e456bdc74 bench: let the verdict govern the report, and put the caliber in the table 
A pair judged incomparable was still followed by a speedup range on the next
line. A NO_TRITON pair's range says nothing about the switch — nothing reached
the compiler — and a NO_IR_DIFF pair's range is the machine's noise floor for
that operator, which is useful but is not a result. Printing either unlabelled
produces exactly the thing this tooling exists to prevent: a table that looks
like a finding. NO_ROWS and NO_TRITON now print no range; NO_IR_DIFF prints one
and says what it is — how far it sits from zero is the confidence floor for a
single measurement of that operator.

screen.tsv gains the seven caliber columns, read back through
`batch_summary.py --caliber`, so CALIBER_FIELDS stays the single definition and
the screening table does not restate it. Two screen.tsv files taken at
different --level are otherwise indistinguishable side by side, and those
columns are the only thing that would stop the comparison.

Aharrypotter a11863399a bench: bound each screening pair and record what it cost 
Screening is first contact with an operator, which makes it the place most
likely to meet one that hangs — and it had no upper bound at all, so a single
operator could hold the whole pass indefinitely. The entire argument for
having a screening step is that it is fast.

CELL_TIMEOUT (default 2400s, as in ab_repeat.sh) now caps each side, and a
truncated pair says so instead of being folded into the dtype explanation: rc
124/137 is a cost problem, not a verdict about the switch.

elapsed_before/elapsed_after join screen.tsv. The two-step design rests on the
ratio between a pair and six rounds — 0.8 minutes against 13-44 on S5000 — so
the pass should record its own half of that ratio rather than leave it to be
reconstructed from directory timestamps.

Aharrypotter 1fd3abd56d bench: rename NO_KERNEL to NO_TRITON and say what it rules out 
"NO_KERNEL" reads as "this operator has no kernel", which is not what the
verdict means and not usually true. It means the run compiled no Triton
kernel: the operator may have run perfectly well through aten or a vendor
library, and a GPU kernel certainly executed. What is absent is anything for
the Triton compiler pass under test to act on.

The note now says that, and says the one alternative explanation is already
ruled out: run_pytest.sh gives every run its own TRITON_CACHE_DIR, so zero
.ttgir cannot be compilation skipped by a warm cache.
 2026-09-10 17:00:45 +08:00
Aharrypotter 4d69320139 bench: let ab_rlc_test.sh decide which operators are worth six rounds 
zl_bench already had the screening mechanics — ab_rlc_test.sh runs exactly one
config-pinned pair per operator (before records, after replays it) against the
vendor-prefixed RLC switch. I had started a second script for the same job
instead of extending this one; that is removed.

What the existing script could not tell you is whether the pair is worth
following with six rounds, which costs 13-44 minutes per operator against
about 0.8 for the pair. It now writes a verdict per operator to
<root>/screen.tsv, and three of the four are not "the switch does nothing":

  IR_CHANGED  the two sides' ttgir differ         -> measure it
  NO_IR_DIFF  byte-identical, configs pinned      -> skip it
  NO_KERNEL   rows but no .ttgir                  -> never reached Triton here
  NO_ROWS     no measurements                     -> usually the dtype

The criterion is the ttgir fingerprint, not the convert_layout count: equal
counts do not mean equal generated code, and what the A/B measures is whether
the generated code changed. Counts are still recorded — they say what kind of
change it was. The fingerprint comes from _ir_fingerprint.sh, shared with
ab_repeat.sh's round-1 check so the two cannot drift apart.

OPS entries take an optional per-operator dtype and default to the operator's
own set. Forcing one dtype across a list is how fft got written off as
unrunnable on MUSA: it only accepts complex64.

Output moves under runs/ab_rlc_<ts>/<op>_{before,after} with OUT_DIR set
explicitly, rather than recovering the directory with `ls -dt runs/<op>_*`.
That lookup is correct while one process runs operators in series, which is
the only way it has been used; it stops being correct the moment several cards
share runs/.

Aharrypotter 2fbfe1dd16 bench: make screening a first-class step with the same caliber as the A/B 
Six rounds of A/B cost 13-44 minutes per operator on S5000 (rand, 15 shapes:
13.0 min; sort, 25 shapes: 43.4 min). Screening one costs about 0.8 minutes —
21 operators in 15.0 minutes, which knocked 13 of them out of the expensive
queue and cut it from ~7 hours to ~2.7. That ratio is the whole argument for
having a separate first step.

Screening was being done by ad-hoc scripts living in the results tree, and
those got two things wrong that this codebase already knows better than:

Both sides ran `record`. Each swept autotune independently, so the two sides
compiled different configs and produced different IR for reasons that have
nothing to do with the switch — every operator would screen as "changed".
screen.sh pins configs exactly as round 1 of ab_repeat does: A records, B
replays A.

The criterion was the convert_layout count. Equal counts do not mean equal
generated code, and what the A/B measures is whether the generated code
changed. The ttgir fingerprint decides; the cvt counts are still recorded,
because they explain what kind of change it was.

Four verdicts, and three of them are not "the switch does nothing":
IR_CHANGED (measure it), NO_IR_DIFF (skip it), NO_KERNEL (the operator never
reached Triton on this backend), NO_ROWS (it did not run — usually the dtype).
The last two are runnability problems being mistaken for switch results, which
is how `fft` got written off: the screen forced DTYPES=float16 on every
operator and fft only accepts complex64. OPS entries now carry an optional
per-operator dtype and default to the operator's own set.

ir_fingerprint moves to _ir_fingerprint.sh so screening and the A/B cannot
drift apart on the criterion.

Aharrypotter 5236d0745f bench: fingerprint only the IR, and refuse to compare when there is none 
ir_fingerprint hashed every file under the dump directory, which includes
index.tsv and naming.md. An operator that compiles no Triton kernel at all
leaves only those two, identical on both sides, so the switch-effectiveness
check reported "byte-identical ttgir" and skipped the operator with
SWITCH_NO_IR_DIFF — "the switch changed no generated code" — when the truth
was that nothing was generated. router_gemm on MUSA is exactly this case: its
kernel cannot be instantiated there (missing BLOCK_M/N/K/SPLIT_K from the
autotune path), zero .ttgir files, and the check called it a no-op switch.

Now only *.ttgir files are hashed, and a run with none returns failure so the
caller treats it as "no comparable IR" rather than "identical". The message on
that path says so, and says explicitly that it does not mean the switch is
inert.

Aharrypotter 551ffbbb77 bench: exit the sampler quietly when its reader goes away 
Piping `telemetry.py --run` into anything that stops reading first — head, or
the campaign shutting the sampler down — raised BrokenPipeError and printed a
traceback. Under ab_repeat that traceback lands in telemetry.err, where it
reads as "telemetry is broken" rather than "telemetry ended normally", and
telemetry.err is exactly the file someone checks when the clock record looks
short.

Swallowing the exception alone is not enough: the interpreter flushes stdout
again on exit and emits a second "Exception ignored" to stderr, so stdout is
pointed at devnull the way CPython documents.
 2026-09-10 16:10:15 +08:00
Aharrypotter 4329b0c835 docs: stop claiming non-CUDA backends never attempt graph capture 
Both the _timing_plugin docstring and the README env table still described the
behaviour from before MUSA declared supports_cuda_graph: "other backends do
not attempt CUDA Graph at all", "非 CUDA 即使设 1 也拒绝". Capture selection has
been driven by the backend capability, not by "is this CUDA", since the MUSA
fallback policy landed. Reading the old text is most likely why the S5000
campaigns were launched with ZL_ENABLE_CUDAGRAPH=0 without anyone checking
what auto would do.

Also states what timer=cuda_graph does and does not mean, since the two are
easy to conflate: it says capture was attempted. Measured on S5000 with auto
and configs pinned, dropout/rand/masked_select select the graph path and then
fall back on every single shape — BENCHMARK_DIRECT_NO_CUDAGRAPH on all 15
rows, zero poisoned, zero rows lost — so the whole table is direct-timed under
a cuda_graph label. ZL_ENABLE_CUDAGRAPH=0 selects the same path and records it
plainly, which is why the existing campaign data stands as measured.

Aharrypotter ee5f70fa89 bench: record device clocks, temperature and power for the whole campaign 
A 6-round A/B here reports side noise at the 0.01% level. Clock throttling and
thermal drift move latency by far more than that and leave no trace in
run.log, so the report comes out looking exactly as clean as a run on a stable
machine. The NV run that reproduced PR763 sampled nvidia-smi every 5s
alongside the campaign; the MUSA campaigns had no equivalent, and the parallel
plan makes it worse by heating the whole box.

telemetry.py samples through the backend, so cuda and musa emit the same
columns (index, sm_clock_mhz, mem_clock_mhz, temp_c, power_w, util_pct) and
two machines' campaigns can be read side by side. mthreads-gmi offers no CSV
query mode, so the MUSA path parses --json and strips the units glued onto
each value ("36C", "1888MHz", "477.68W"); its "Power Draw " key carries a
trailing space, matched by stripping rather than by literal.

The device comes from the backend's own visibility variable when not pinned. A
list of devices resolves to no -i at all, sampling every one, rather than
silently picking the first. Dropping the placeholder drops its flag too: a
bare trailing -i fails the sampler instead of widening it.

Telemetry is evidence, not a gate. A missing or unpermitted sampler exits
quietly with its reason in telemetry.err and the campaign runs unchanged.

Aharrypotter d45806eacd bench: log every A/B cell as it finishes, and cap it with a timeout 
The three markers the README requires be checked — AUTOTUNE_REPLAY_FALLBACK,
BENCHMARK_DIRECT_NO_CUDAGRAPH, BENCHMARK_CAPTURE_POISONED — were only
reachable by grepping run.log afterwards, which happens when someone
remembers to. The NV run that reproduced PR763 wrote a per-cell status row
instead; a 6-round campaign here had no equivalent, so a missing cell, a
stalled cell, or a marker count going from 0 to nonzero was invisible until
the batch ended.

run_cell now writes round/op/side/switch/rc/elapsed_s/success/failed plus the
three marker counts to <root>/status.tsv as each cell completes, and wraps the
cell in CELL_TIMEOUT (default 2400s, matching the NV run) so one hung cell
cannot hold the batch. rc 124/137 is called out by name.

grep -c prints 0 and exits 1 when it finds nothing, so each count swallows its
status; without that the bookkeeping itself would mark a clean cell failed.

Aharrypotter 92f3d150c7 bench: preflight the interpreter, not just the paths 
triton normally comes from a PYTHONPATH pointing at a compiler build and
flag_gems from a source checkout, so a shell that reaches every correct path
can still be the wrong Python. run_pytest.sh checked that the FlagGems
directory and benchmark file exist and then handed the run to pytest, where
the real problem surfaced per cell as `pytest exit 4` from a conftest
ImportError.

A multi-round campaign burns every cell that way before anyone reads a log:
today's noise-calibration run lost 12 measurement cells and 160 load runs to
`ModuleNotFoundError: No module named 'triton'`, each failing in under a
second and each looking, from the outside, like a cell that ran.

The check names the interpreter it used, since which Python is on PATH is the
whole question. Its stderr redirect stays on the child — putting `2>/dev/null`
on the preflight call swallows preflight's own `>&2` message and turns a named
refusal into a bare exit 3.

AharrypotterandClaude Opus 5 c95474a432 bench: refuse to report a comparison whose two sides have different calibers 
Two runs on different calibers produce a report that looks exactly like a
valid one — no step errors, the numbers just mean something else. This repo
has published three figures that were an artifact of such a difference:
router_gemm -8.2% (record vs record), mm "945 variants -> 33" (shared vs
inherited libtuner cache), replication_pad3d +43% vs +124.5% (timer).

batch_summary --ab / --ab-rounds now reads every participating run's
run_identity.json and compares backend/device/timer/bench_level/shape_mode/
tuner_cache/direct_repeat before parsing a single latency. Mismatch, or a
missing identity, prints !!! [caliber] and exits 4. autotune_mode is judged
separately: record pinning a replay is the normal shape, both sides record
is the exact trap above and is refused by name. --allow-caliber-mismatch
releases it, still printing what it found.

Recording on a *shared* tuner cache warns rather than refuses: the pinned
config depends on what else ran on the machine, which leaves relative
conclusions intact and absolute latencies unquotable. Refusing it would
reject the default every A/B here currently uses.

ab_repeat.sh closes the one axis that had no check: after round 1 it
fingerprints both sides' ttgir (relative path + content, so a changed
variant *set* counts too). Byte-identical means the switch changed no
generated code for this op, and the remaining N-1 rounds would measure
noise and report it as "no difference" — so the op is skipped with
SWITCH_NO_IR_DIFF unless SWITCH_ALLOW_NO_IR_DIFF=1.

README leads with a caliber table: each axis, its measured magnitude, what
pins it, and which code checks it. The fourth column is code because
documentation did not hold — the README already said "the B side must use
REPLAY_FROM" when the record-vs-record number was published.

AharrypotterandClaude Opus 5 aa147c938e feat: repeat an A/B over rounds and report whether the verdict holds 
A single pair cannot say whether its own verdict is stable, and on this device
that is not a theoretical gap. Measured on an S5000, topk eliminated 32
convert_layout ops yet 17 of its 42 shapes changed the SIGN of their delta
between two equally valid runs. The cause is not the timer: graph capture and
direct timing agree to 1.00x on that operator, and the verdict moved a median of
1.1pp between them, inside the 1.7pp noise floor a same-timer control
established. The deltas are simply near zero, and one measurement cannot orient
them.

ab_repeat.sh runs an A/B over N rounds in independent processes. Round 1's A
side records the autotune configs and every later run -- including A's own later
rounds -- replays that one set, so configs are pinned across rounds and sides and
only the switch under test and measurement noise remain. Round order alternates
to cancel one-directional drift. An operator with a failed round gets no report,
since a report missing rounds reads exactly like a complete one.

batch_summary --ab-rounds aggregates <root>/r<k>_<A|B>/run.log and separates the
two dispersions, which answer different questions and were previously conflated:
the spread within one side's samples says how noisy the machine was, while the
spread of the per-round deltas says whether the verdict holds. Shapes whose
delta changes sign across rounds are counted and called out, because their
direction is not a conclusion at any timer.

The path is already validated on NVIDIA: six rounds narrowed router_gemm to
-16.6% ~ -16.2% with 0.4% side noise, which is what turned a single pair into a
statement.

AharrypotterandClaude Opus 5 9665d36a7c feat: allow the direct timer to repeat and take the median 
do_bench already returns a median over the iterations inside one call, which
suppresses iteration-level jitter. It cannot see drift across a call: clocks
ramping, another process arriving. Direct timing is where that shows, because
it walks the full Python launch path once per iteration, so on small kernels the
number carries launch overhead and CPU jitter that graph capture removes.
ZL_DIRECT_REPEAT=N repeats the call and takes the median over calls, which is
the layer the inner median misses. It defaults to 1, so nothing changes unless
asked.

The knob covers both ways a row ends up on the direct timer: a run that selected
timer=direct outright, and the rows a captured run falls back on, whose marker
now carries repeat=N since those rows were already a different caliber from the
captured ones and can now also be a different sample count. Repetition is
skipped when the caller asks for quantiles or return_mode "all", because the
result is then a sequence and a median across calls is undefined for it.

On MThreads this is not a refinement. A convert-reduction screen over 21
operators puts the largest reductions at sort (65->15), dropout (48->0) and
rand (24->0), and all three are exactly the operators that cannot be
graph-captured there -- RNG seeding and a capture-illegal stream op. The
headline numbers on that device are produced by the noisiest timer, which until
now had no repetition at all.

_cudagraph_plugin imports triton at module scope, so the tests load it against a
stub: the repeat logic is arithmetic and should stay testable without a GPU.

AharrypotterandClaude Opus 5 d7cb7efc94 fix: have the campaign worker ask zl_bench for its plugin list 
The worker carried a hand-copied plugin array, taken from zl_bench before
backends/ existed, and it had drifted twice over. It still named
_device_guard_plugin, which is now a shim for _device_setup_plugin. More
consequentially it carried no timing plugin at all, so every measurement this
campaign ever sealed was timer=direct while zl_bench's own driver had been
capturing -- a difference the harness never reported, because the missing plugin
cannot announce itself.

It now calls plugin_plan.py with ZL_BACKEND=musa and uses whatever comes back,
so the caliber follows the backend's declared capabilities instead of a snapshot
of them. The plan is preflighted for non-emptiness, since an empty array would
silently run pytest with no plugins at all: no shape injection, no autotune
record, no IR dump, and a table that still looks well-formed.

Two effects on this campaign. _timing_plugin now enters the list, and since
MUSA declares graph capture the worker will capture where the operator allows
it; operators that cannot are marked per row, as on any other backend. And
_parallel_warmup_plugin joins, inert unless PARALLEL_WARMUP_GPUS is set.

The sealed 32-workload run therefore sits on the far side of a caliber change
and is not comparable with anything produced after this commit. Re-running it is
a campaign decision, not a harness one.

The worker test asserted the literal "-p _musa_benchmark_compat_plugin"; it now
asserts the delegation and that no -p is spelled out locally. What the plan
holds for musa is covered where it belongs, in zl_bench's test_backends.

AharrypotterandClaude Opus 5 75405cc555 Merge the S5000 MUSA RLC product campaign 
Brings in campaigns/musa_rlc_product/: the runner, its worker, manifest
validation, the sealed 32-workload manifest, a topology re-accounting tool and
their tests. Developed on a fork branch that never reached main, and it merges
without conflict because it only adds a new directory; the one file it shares
with main, _musa_benchmark_compat_plugin.py, is byte-identical to the copy
already committed here.

The campaign layer sits above zl_bench rather than inside it: freezing a
workload set, classifying outcomes, and producing receipts, where zl_bench turns
one operator into one reproducible measurement. Two of its ideas are worth
naming because they are absent below it. Narrowing what a workload measures --
which correctness variant, which benchmark case -- requires a stated reason that
manifest validation enforces, so an exclusion stays visible in review. And
reaccount_musa_rlc_topology.py re-derives verdicts from sealed artifacts under a
corrected accounting rule without re-running anything, while refusing to promote
a workload on the new count, only to demote it.

Its worker still hardcodes a plugin list copied from a pre-backends zl_bench,
which is why the campaign has been timing with timer=direct. Switching it to
plugin_plan.py is the next change and will alter its caliber, so the sealed run
is not comparable across that boundary.

AharrypotterandClaude Opus 5 29af59be9b feat: absorb the MThreads compat plugin and the A/B range report 
Three pieces from the fork's feature/musa-benchmark-support branch that never
reached main, rebased onto the backend abstraction rather than copied verbatim.

_musa_benchmark_compat_plugin drops FlagGems benchmark skip guards written as
`torch.cuda.is_available()` where the code under test dispatches through
flag_gems.device. On MThreads those turn a working operator into "not measured":
test_fft.py skipped entirely, and unskipped on an S5000 it produces 25 rows. The
plugin pins each override to one file and one exact skip reason and only acts
when flag_gems has dispatched to the mthreads vendor; two guards were probed on
device and deliberately left in place, which is why they are named in its
docstring rather than silently absent.

It is wired through a new DeviceBackend.compat_plugins rather than a name test
in the planner, so the policy stays where every other backend difference lives.
Compat plugins are planned first because they rewrite collection-time markers
and nothing may read the item list before them; a test pins that position and
another pins that they do not leak to other backends.

batch_summary gains --ab: the speedup column compares gems against torch, not
one build against another, so an A/B needs the two run.logs paired by operator,
dtype and size detail. Only rows that succeeded on both sides with a positive
latency count, so an incomplete pairing cannot look like a complete range, and
the range is annotated when either side carries a BENCHMARK_DIRECT_NO_CUDAGRAPH
marker, since a fallback row was timed under a different regime.

ab_rlc_test.sh is the same caliber as ab_fold_test.sh with the comparison axis
moved to FLAGTREE_<VENDOR>_RLC_ENHANCE. Both are caliber examples, not
regression scripts: if the switch under test no longer exists the script still
runs every round and prints a full table showing no difference, so confirm the
axis is live before reusing either.

AharrypotterandClaude Opus 5 c9f9b7885f feat: check the run's preconditions, and record which tuner cache it used 
Two failure modes that cost this harness real results, both of them silent.

A wrong path does not fail as a wrong path. pytest cannot collect a benchmark
directory that is not there, so benchmark/conftest.py never registers --level
and --mode, and the run dies with "unrecognized arguments: --level core --mode
kernel" -- an error about the flags, several layers away from the missing
directory. run_pytest.sh now checks the FlagGems directory, the benchmark file,
SHAPE_FILE and REPLAY_FROM before starting pytest, prints
"PREFLIGHT_FAILED check=<the named check>" and exits 3, distinct from pytest's
own 1 and 4 so the batch layer can tell a broken environment from a broken
operator. Only the file half of a node is checked; a missing ::test_<fn> already
produces a clear "not found: ..." from pytest and needs no help.

FlagGems keeps libtuner winners in a sqlite DB under $FLAGGEMS_CACHE_DIR
(default ~/.flaggems), shared by every run on the machine. Whichever side of an
A/B runs first therefore hands its winners to the second, which then compiles
only those: measured on router_gemm, the second of two shared-cache runs
compiled 10 variants instead of 234 and finished in 17s instead of 52s. That is
how an mm A/B in this repo produced "945 variants -> 33, 136 converts -> 10" and
read as a compiler result when it was cache inheritance; isolated, both runs
compile 234.

ZL_ISOLATE_TUNER_CACHE=1 gives a run its own cache directory, dropped afterwards
with the Triton one since the chosen configs are already in autotune_records/.
It defaults to 0, because cold tuning is expensive and the standard REPLAY_FROM
A/B pins configs anyway; only record-against-record is exposed. The default is
unchanged, but the caliber is no longer invisible: either way it goes into the
run header and run_identity.json as tuner_cache, which is what was missing when
the mm numbers could not be explained after the fact.

AharrypotterandClaude Opus 5 ac818291a6 feat: turn on graph capture for MUSA 
supports_cuda_graph was False for MUSA, so every run there was pinned to
timer=direct. That was correct when it was written -- the capture path named
torch.cuda and could not have worked -- but it is not correct now, and the two
timers are not interchangeable: direct timing walks the full Python launch path
per iteration, so on small kernels it measures mostly launch overhead. Measured
on an S5000, capture against direct: batch_norm 16x16x8x48 0.0758ms -> 0.0089ms,
tanh and gelu at 4096x4096 about 3.3x, GEMMs unchanged at 1.00x. Leaving it off
discards that on every operator that can capture, and it also puts MUSA on a
different caliber from the CUDA numbers the harness is meant to compare against.

torch_musa supplies Stream, Event, synchronize, graph and MUSAGraph, so capture
works through the device interface. Verified on an S5000 over five operators,
one per path:

  tanh      captured, no marker
  dropout   15/15 rows fall back: MUSAGeneratorImpl::current_seed is not
            callable during capture
  rand      same
  perf_sort 25/25 rows fall back: operation not permitted when stream is
            capturing
  unique2   denied up front; rc=0 with 10 rows

MUSA gets its own error wording; none of the CUDA markers match it. "MUSA
error: unknown error" during capture is classified as poisoning rather than
recoverable, because the fallback runs and the process then dies in teardown:
before the deny entry was keyed correctly, unique2 reproduced exactly that,
ending at rc=1 with no rows, but now under an explicit BENCHMARK_CAPTURE_POISONED
marker instead of a bare ExceptionGroup.

capture_deny_ops is keyed by FLAGGEMS_PERF_CURRENT_OP, which holds the pytest
FUNCTION name minus `test_` -- unique2, perf_sort -- not the benchmark file
name. Getting that wrong fails open silently, which is how the first attempt
still hit rc=1 with the entry written as "unique"; a test now pins the key
space. The plugin-plan test is renamed because its assertion that
_cudagraph_plugin is absent from the plan holds on CUDA too and says nothing
about capture support.

AharrypotterandClaude Opus 5 6fa5f5d7a2 refactor: let any backend own graph capture and its failure modes 
Two things kept graph-capture timing tied to NVIDIA, and both are mechanism
rather than policy, so neither backend's behaviour changes here.

The capture path named torch.cuda directly for stream, event, synchronize and
the graph type. FlagTree's do_bench already resolves those through
driver.active.get_device_interface(); its do_bench_cudagraph does not. On a
non-CUDA device every capture therefore raised and every row silently took the
fallback while the log still reported capture as enabled. The path now takes
those calls from the interface, with _graph_class picking CUDAGraph or
MUSAGraph. CUDA still calls upstream's do_bench_cudagraph verbatim, so its
numbers do not move; the port only matters where upstream cannot run.

Failure classification moves onto DeviceBackend, because the text it matches is
vendor wording that has no meaning on another runtime, and gains a third
verdict. A kernel refusing capture is ordinary and falls back. A kernel failing
on the device is fatal and re-raises, since a fallback latency there would
report a broken kernel as a measurement. New: the capture ATTEMPT can leave the
context unusable, and falling back then measures inside a dead process -- the
observed shape of that is a fallback marker followed by a teardown crash and
zero rows. Those raise under BENCHMARK_CAPTURE_POISONED instead, naming the
operator as capture-incompatible rather than broken. capture_deny_ops skips the
attempt entirely for operators already known to do this, because for them the
attempt is the damage and rediscovering it per shape costs the run.

CUDA's marker list is carried over unchanged and no poisoning wording is
guessed for it. The scratch-RNG guard around capture is skipped when an
interface exposes no default_generators, since there is then no registration to
protect.

AharrypotterandClaude Opus 5 783c0655bc fix: never let the parallel sweep cover only part of the shape set 
The sharded autotune sweep could publish a config set with holes, and a run
using it reports itself as replaying while every uncovered key silently
self-tunes. That is the exact failure the record/replay caliber exists to
prevent, and it was reachable two ways.

Shape lookup was op_name-only, but BLAS operators keep their shapes under the
class name: core_shapes.yaml has BlasBenchmark, not mm. Every BLAS operator
therefore resolved to zero shapes and the plugin disabled itself with a message
that read like a normal skip. It now walks the benchmark class chain the way
FlagGems' set_shapes does. The chain is recovered statically -- the class comes
from the op_name= keyword of the constructor call in the test module, its bases
from that module plus benchmark/base.py -- because the plugin runs at
pytest_configure, before any Benchmark instance exists. Resolved keys are named
in the log, and a total miss lists the candidates it tried.

Two cases can still produce partial coverage, and both now refuse rather than
shard a subset:

- --level comprehensive, where set_shapes() merges set_more_shapes() on top of
  the yaml. That addition is arbitrary per-subclass Python and invisible here.
  Measured on mm: 5 of 29 shapes swept, 90 AUTOTUNE_REPLAY_FALLBACK
  reason=key_missing in the run that consumed the result.
- a shard exiting non-zero, whose shapes were never swept. This used to append a
  WARNING to a success message and publish the merge anyway; observed with 3 of
  5 shards dead. The whole sweep is now discarded, worker logs kept.

Both fall back to the normal serial sweep, which costs wall time rather than the
same-config premise.

AharrypotterandClaude Opus 5 92dae82c7f feat: expose the upstream benchmark level as BENCH_LEVEL 
run_pytest.sh hardcoded --level core, so the only shapes ever reachable were
each operator's core_shapes entry. FlagGems merges a subclass's
set_more_shapes() on top of that at --level comprehensive, and for BLAS that
addition is where the large GEMMs live: mm goes from 5 shapes to 29, taking in
four large-K tuples plus models_shapes/*.yaml, with N/K up to 152064. The
comprehensive path also yields each shape a second time (transposed, for BLAS),
so the case count doubles. None of that was reachable without editing the driver.

BENCH_LEVEL defaults to core, so existing runs are unchanged, and rejects
anything other than core/comprehensive rather than passing it through to pytest.
The chosen level is echoed in the run header, written into the archived
shapes.yaml, and recorded in run_identity.json, because an A/B whose two sides
used different levels is not comparable and is otherwise invisible afterwards.

Sweep cost scales with the shape count, so comprehensive on a BLAS operator
wants PARALLEL_WARMUP_GPUS.

AharrypotterandClaude Opus 5 c8ea586d0f feat: make the harness backend-agnostic 
Everything about which accelerator a run targets was previously spelled CUDA:
device discovery went through nvidia-smi, pinning through CUDA_VISIBLE_DEVICES,
the vendor guard only recognised NVIDIA, and the -p plugin list was hardcoded in
run_pytest.sh with no way to drop the CUDA-only members. Running the same
operator corpus on another vendor's device therefore meant editing the drivers.

The selection now hangs off one ZL_BACKEND variable (cuda/musa/rocm/ascend, with
the usual aliases):

- backends/ owns per-backend device enumeration, visibility env keys and
  capability flags, so nothing above it names a vendor;
- plugin_plan.py derives the -p list from those capabilities instead of a
  hardcoded array, which is what lets a non-CUDA run omit the graph-capture and
  cluster-fix plugins rather than watch them fail;
- _timing_plugin selects the timer from the same capabilities: CUDA keeps
  graph capture with its per-shape fallback, other backends stay on upstream
  do_bench and record timer=direct, because capture-then-fallback on a device
  without graph support only produces noise;
- _device_setup_plugin replaces the NVIDIA-only vendor guard;
- providers/flaggems.py resolves the pytest node, so a caller may pass TEST_NODE
  directly instead of the OP/OP_FILE pair, and SHAPE_MODE=upstream can defer to
  FlagGems' own core_shapes;
- _run_identity.py writes run_identity.json next to each run, recording backend,
  device, timer, autotune mode and the resolved test node. Two runs whose
  calibers differ are otherwise indistinguishable after the fact.

run_batch gains --backend and --devices (--gpus kept as an alias) and carries
backend/device/timer into ops_status.csv. test_backends.py covers the registry,
alias resolution, visibility env and plugin planning.

AharrypotterandClaude Opus 5 35a928a516 chore: pin shipped text formats to LF 
Everything in this repository runs on Linux accelerator hosts, and campaign
receipts record the SHA-256 of the harness files that produced them. With Git's
default autocrlf on Windows a checkout rewrites the shell drivers with CRLF,
which breaks them outright on the target host and changes every recorded digest.

The two inventory CSVs are renormalized here because their content is unchanged;
the remaining files normalize as part of the commits that actually modify them.

Aharrypotter e970ed94c2 docs: document the MUSA RLC campaign 
Covers the three screen cells and why replay locks them to one variable, how to
freeze and run a campaign, what the runner refuses to start on, the six
classifications, and the three scoping rules that decide whether a verdict
means anything.

Also states what a terminal campaign does not prove, since the manifest fixes
production_default_policy to unchanged-off and a passing run is not an argument
for flipping it.

Aharrypotter 8a685638bb feat: re-account a sealed MUSA RLC run without re-running it 
A sealed run already holds every TTGIR dump and its launch index, so a change
in how convert topology is counted can be applied to it directly instead of
spending accelerator time.

The tool re-reads each cell's dump, recomputes the scoped count, re-runs the
campaign classifier against the sealed correctness verdicts, and writes a
derived receipt and matrix outside the run root. It refuses to write inside a
sealed run and rejects a directory with no campaign receipt.

A derived verdict can only demote a topology claim. Promoting one to G or C
needs reversed-order timing, which a sealed run holds only for tasks that
already showed a reduction, so a reduction appearing for the first time under
scoping is reported as X for missing round-b evidence rather than guessed.

Run against the sealed 32-workload S5000 campaign, a floor of 1 changes exactly
one task: gelu_backward moves from C to B, and the only excluded files in the
whole campaign are its five once-launched randn_kernel dumps. A floor of 0
reproduces the sealed counts with no task changed, which is the equivalence
that makes the scoped number auditable rather than merely different.

Aharrypotter 8bbea472bb feat: add the S5000 MUSA RLC product campaign 
A frozen 32-workload campaign that measures how FlagTree's RemoveLayoutConversions
pass behaves on a Moore Threads S5000, through FlagGems public dispatch and this
repository's existing plugins.

The manifest is the contract: source commits, the single physical device, the
three screen cells off/mask0/candidate, the native-event timer, and per-workload
dtypes, timeouts and canary membership. prepare validates it against
ops/inventory_main.csv and freezes an immutable task matrix; the runner executes
the matrix serially, and the worker drives one operator cell through pytest with
_ir_meta_plugin, _autotune_record_plugin and the rest.

Three properties are worth calling out because they decide whether a verdict
means anything.

Convert topology is scoped to the measured operator. A benchmark call builds its
inputs once and then runs the operator many times under the timer, so counting
ttg.convert_layout over every executed kernel credits the candidate with
converts removed from input construction that no timer can observe. Each dumped
TTGIR file is joined to its launch count from index.tsv and only variants
launched more than measured_launch_floor contribute; the unscoped total and the
excluded files stay in the receipt, and a cell that cannot be joined to its
index is classified X rather than trusted.

Correctness is scoped to the variant a workload measures. Running a whole test
file lets an unrelated variant decide the verdict, so a workload may pin node
ids or a -k selector, never both, and any narrowing must state its reason.

Targets are resolved before the campaign starts. The inventory can lag the
pinned FlagGems commit, and such a task previously failed only inside the
worker's preflight, which exited silently and left an empty log. The runner now
resolves every benchmark and correctness target against the real tree, a
workload may name a target the inventory does not know about if it says why,
and each preflight check names itself on failure.

Aharrypotter 22139e4b87 chore: pin shipped text formats to LF 
This repository's drivers are shell scripts executed on Linux accelerator
hosts, and its consumers record the SHA-256 of the files they ran. With Git's
default autocrlf on Windows a checkout rewrites those files with CRLF, which
breaks the shell drivers outright and changes every digest a receipt refers to.

Aharrypotter 3b54f458e6 feat: add a MThreads benchmark compatibility plugin 
Several upstream FlagGems tests gate themselves on torch.cuda.is_available()
even though the code under test runs on whatever accelerator FlagGems
dispatches to. On MThreads those guards skip the operator instead of
exercising it, so a working path reports as "not measured".

The plugin drops such a guard only when it is pinned to one file and one exact
skip reason, only when FlagGems has dispatched to the MThreads vendor, and only
after the unskipped test was observed to pass on an S5000. It walks the node
chain rather than the item's own markers, because a module-level pytestmark
does not appear on the item.

Two guards were probed on device and deliberately left in place, which is why
they are named in the module docstring rather than silently absent.
test_grid_sample.py builds its inputs through a helper whose device argument
defaults to the literal "cuda": unskipped, all 90 collected cases fail in
aten::empty on a CUDA backend that is not present. test_cutlass_scaled_mm.py
gates on vLLM as well as CUDA, so removing its guard would raise on the missing
dependency instead of measuring anything.

## 先读这个：口径决定数字的含义
同一个算子、同一台机器、同一份代码，换一条测试口径，测出来的数字可以完全不同。
下表每一行都是本仓踩过的，量级是实测的，不是估计：
| 口径轴 | 改一下的量级 | 由谁固定 | 由谁检查 |
|---|---|---|---|

| timer（cuda_graph vs direct） | replication_pad3d 从 +43% 变成 +124.5% | `ZL_TIMER` / backend 能力 | 同上，`timer` 字段不一致即拒绝 |
| libtuner 持久缓存（共享 vs 隔离） | mm 看起来从 945 个变体降到 33 个——实际是 B 侧继承了 A 侧的缓存 | `ZL_ISOLATE_TUNER_CACHE=1` | 共享缓存上 record 会打 `警告 [caliber]` |
| `--level core` vs `comprehensive` | mm 的 shape 数 5 → 29，能不能覆盖到大 GEMM 全看这个 | `BENCH_LEVEL` | `bench_level` 字段不一致即拒绝 |
| 重复轮数 | 收益落在零附近时，单次测量给不出方向：topk 42 个 shape 有 17 个在两次等效运行间翻了符号 | `ROUNDS` / `ZL_DIRECT_REPEAT` | `direct_repeat` 字段不一致即拒绝 |
| 被测开关本身是否真的接上 | 开关名拼错，两侧跑同一份代码，脚本照样报出"无差异" | 开关名正确 | `ab_repeat.sh`：第 1 轮后比两侧 ttgir 指纹，相同即跳过该算子 |
**结论：一次运行的数字没有意义，只有一对同口径运行的差值有意义。** 每次运行把自己的
口径写进 `runs/<run>/run_identity.json`；`batch_summary.py --ab` / `--ab-rounds` 在出
报告前核对这些字段，不一致就拒绝，因为**口径不同的两次运行会产出一份和有效报告长得
一模一样的表**——没有任何一步会报错，只是数字换了含义。确认两次运行确实可比时，用
`--allow-caliber-mismatch` 显式放行。
文档拦不住人：README 里早就写着"B 侧必须走 REPLAY_FROM"和"只有 record 数据支撑的
结论按未验证处理"，本仓仍然发布过一个 record 对 record 得到的 router_gemm 数字。
所以上表第四列是代码，不是提醒。

## 两步：先筛选，再实测
跑一个算子的六轮 A/B 要 13~44 分钟（S5000 实测：`rand` 15 shape 13.0 分钟，
`sort` 25 shape 43.4 分钟）。用 `ab_rlc_test.sh` 筛一对只要约 0.8 分钟。
**差 20~50 倍**，所以先筛后测：
```bash
# 第一步：一对定去留（A 侧 record，B 侧 REPLAY_FROM 它，config 锁死）
OPS="col2im:col2im topk:topk perf_fft:fft" VENDOR=MUSA bash ab_rlc_test.sh
# 第二步：只把 IR_CHANGED 的送进来
SWITCH=FLAGTREE_MUSA_RLC_ENHANCE ROUNDS=6 OPS="topk:topk" bash ab_repeat.sh
```
`ab_rlc_test.sh` 除了原有的 speedup 区间，还给每个算子写一行判定到
`<root>/screen.tsv`：
| 判定 | 含义 | 该怎么办 |
|---|---|---|
| `IR_CHANGED` | 两侧 ttgir 不同 | 排六轮 A/B |
| `NO_IR_DIFF` | 逐字节相同（config 已锁死） | 跳过。跑六轮只会测到噪声，并报成一个"无差异"结论 |
| `NO_TRITON` | 跑出了行，但没编出 `.ttgir` | 本次运行没有任何东西经过 Triton。算子本身可能完全正常——多半跑的是 aten 或厂商库的 kernel——只是被测的编译器 pass 没有作用对象。**既不是"开关无作用"，也不是"没有 kernel"**。`run_pytest.sh` 每个 run 用独立 `TRITON_CACHE_DIR`，所以"缓存命中没重新编译"这个解释已被排除 |
| `NO_ROWS` | 没有测量行 | 先修可运行性：多半是 dtype 不被该算子接受，或它在本后端拿不到 config |
两件容易做错的：
- **判据是 ttgir 指纹，不是 `convert_layout` 计数。** cvt 数相同不等于生成代码
相同，而要测的是"生成代码变了没有"。cvt 数照样记，它解释的是变化的性质。
- **不要全局写死一个 `DTYPES`。** `OPS` 元素支持 `OP:OP_FILE:DTYPES`，留空表示用
该算子自己的全套。`fft` 只吃 complex64，被一刀切的 `DTYPES=float16` 判死过一次
——那是 harness 的问题，被记成了算子的问题。
同一份 `_ir_fingerprint.sh` 也被 `ab_repeat.sh` 用于第 1 轮后的对比轴有效性检查，
两处判据不会漂开。
判定还管住报告：`NO_ROWS` 与 `NO_TRITON` 不出 speedup 区间（前者没有可比的测量，
后者与被测开关无关）；`NO_IR_DIFF` 照出，但明说那是**本机对该算子的噪声底**，不是
开关的收益——它离零多远，就是该算子单次测量的可信下限。判定刚说完这一对不可比，
下一行就给个 `+0.3%`，正是这套工具一路在防的"看起来像结论的表"。
`screen.tsv` 末七列是口径（`backend device timer bench_level shape_mode
tuner_cache direct_repeat`），由 `python batch_summary.py --caliber <run_dir>` 取——
`CALIBER_FIELDS` 只有那一处定义，筛选表不重列一遍。两份不同 `--level` 的
`screen.tsv` 放一起比时，这几列是唯一能拦住的东西。
每对有 `CELL_TIMEOUT`（默认 2400 秒）兜底，超时打 `!!! CELL_TIMEOUT` 并按耗时问题
报告，不混进 dtype 那条解释里。`elapsed_before/after` 也进表：两步流程的全部依据
就是"一对 0.8 分钟对六轮 13~44 分钟"这个比例，那这一步该记下自己那一半。
## 算子跑不起来时的排查清单
`NO_ROWS` / `NO_TRITON` 说的是"这一格没测出东西"，不是"开关无作用"。按下面的顺序查，
每一条都踩过：
| # | 症状 | 查什么 | 实例 |
|---|---|---|---|
| 1 | `PREFLIGHT_FAILED check=interpreter imports triton + flag_gems` | 用的是哪个 python。triton 通常来自 PYTHONPATH 指向的编译器构建 | 一次噪声标定因此废掉 12 格 + 160 次负载 run |
| 2 | `PREFLIGHT_FAILED check=benchmark file exists` | `OPS` 元素是 `OP:OP_FILE`，写反就找不到文件 | `test_perf_sort` 在 `test_sort.py` 里，要写 `perf_sort:sort` |
| 3 | `ValueError: Given dtype(s) '...' can't be supported by this op` | 该算子只吃特定 dtype，别全局写死 `DTYPES` | `fft` 只吃 complex64，被一刀切的 fp16 判成"跑不出行"，而它是 cvt 消除量最大的算子 |
| 4 | `dynamic_func() missing ... BLOCK_M, BLOCK_N ...` 之类 JIT 深处的报错 | **benchmark 是不是导入了别家厂商的实现**（见下） | `router_gemm` 拿 NVIDIA Hopper 的 kernel 跑在 MUSA 上 |
| 5 | 跑出行但 `kernels=0` | 该算子在本后端没走 Triton，走的是 aten 或厂商库 | — |
### 第 4 条：import 成功不等于这个后端支持
FlagGems 的厂商实现放在 `flag_gems/runtime/backend/_<vendor>/ops/`。benchmark 里常见
这种可用性判据：
```python
try:
from flag_gems.runtime.backend._nvidia.hopper.ops.mm import router_gemm
ROUTER_GEMM_AVAILABLE = True # ← import 成功就置 True
except Exception:
ROUTER_GEMM_AVAILABLE = False
```
**`import` 只证明那个 `.py` 在磁盘上，它不碰设备，所以在任何后端上都成功。** gate 于是
形同虚设：MUSA 上照样置 True，benchmark 拿 NVIDIA Hopper 的 kernel 跑在摩尔线程卡上，
最后死在 JIT 深处的 `dynamic_func() missing BLOCK_M, BLOCK_N, BLOCK_K, SPLIT_K`——
**那个报错完全指不向真正的原因**。而 `_mthreads/ops/mm.py` 下明明有一份能用的实现，
benchmark 从头到尾没导入过。
正确写法是先判 vendor（同一个文件里 Cambricon 那支就是对的）：
```python
if base.vendor_name == "nvidia":
try:
from flag_gems.runtime.backend._nvidia.hopper.ops.mm import router_gemm
ROUTER_GEMM_AVAILABLE = True
except Exception:
pass
```
`_device_setup_plugin` 会在 session 结束时扫 `sys.modules`，载入过别家厂商实现时打：
```
FOREIGN_VENDOR_MODULE active=mthreads loaded=nvidia
```
**它不拦，只报**——载入别家模块本身不一定有问题（有些是共享工具），但一个算子结果可疑
时，这行是第一个该看的地方。

### ab_fold_test.sh：A/B 测试参考示例 ### 前置检查
`run_pytest.sh` 在启动 pytest 之前校验 FlagGems 目录、benchmark 文件、`SHAPE_FILE`
与 `REPLAY_FROM`，失败时打 `!!! PREFLIGHT_FAILED check=<具名检查>` 并以 3 退出。
这些检查存在的理由是**静默失败会指向错误的方向**：路径不存在时 pytest 收集不到
benchmark 目录，注册 `--level`/`--mode` 的 `conftest.py` 就没被加载，报错变成
`unrecognized arguments: --level core --mode kernel`，看起来像参数或版本问题。
只校验节点的文件那一半；`::test_<fn>` 交给 pytest，函数不存在时它自己会清楚地报
`not found: ...`。
还校验**解释器**——`python -c "import triton, flag_gems"`。triton 通常来自 PYTHONPATH
指向的编译器构建产物、flag_gems 来自源码检出，所以一个能摸到全部正确路径的 shell
仍然可能是错的那个 Python。不查的话，失败以每格一次 `pytest exit 4`（conftest 的
ImportError）出现，多轮 campaign 会在有人读日志之前把每一格都烧掉——这不是假想，
2026-09-10 的噪声标定实验就这么废了 12 格加 160 次负载 run。报错里带上
`$(command -v python)`，因为要看的就是"用的到底是哪个解释器"。
### 口径核对：出报告前的拒绝
`batch_summary.py --ab` / `--ab-rounds` 在解析任何 latency 之前，先读参与对比的每个
run 目录的 `run_identity.json`，逐字段核对 `backend / device / timer / bench_level /
shape_mode / tuner_cache / direct_repeat`。任何一项不一致，或任何一侧缺 identity，
就打 `!!! [caliber] ...` 并以 **4** 退出，不出报告。
```
!!! [caliber] sort: timer 不一致：before=cuda_graph, after=direct
!!! [caliber] sort: 拒绝出报告。确认口径确实可比后加 --allow-caliber-mismatch
```
单独判 `autotune_mode`：一侧 record 定 config、另一侧 replay 它是正常形态；**两侧都
record 直接拒绝**——那正是本仓发布过错误 router_gemm 数字的那次形态。
不拒绝但会警告的一类：在**共享** libtuner 缓存上 record。被 pin 的 config 取决于此前
在这台机器上跑过什么，相对结论仍成立，绝对延迟与变体数不可跨机器引用。
`--allow-caliber-mismatch` 放行，仍会把问题打出来。用它之前先能说清为什么这两次运行
可比；跨口径引用别人的数字，比自己重跑一遍贵得多。
### 多轮重复：ab_repeat.sh 与 --ab-rounds
单对观测无法说明自己稳不稳。S5000 实测 `topk` 消除了 32 个 `convert_layout`，
42 个 shape 里却有 17 个在两次同等有效的运行之间**改变了 delta 的符号**——那不是
计时口径问题（图捕获与 direct 的延迟比是 1.00x），是收益本身落在零附近、单次
测量给不出方向。
```bash
SWITCH=FLAGTREE_MUSA_RLC_ENHANCE OPS="topk masked_select" ROUNDS=6 ZL_BACKEND=musa FLAGGEMS_DIR=/path/to/FlagGems bash ab_repeat.sh
```
口径：第 1 轮 A 侧 record config，此后每一次运行（含 A 侧的后续轮次）都
`REPLAY_FROM` 那一份，config 因此跨轮跨侧全部锁死；逐轮交替先后顺序抵消单向漂移。
有轮次失败的算子不出报告——缺轮的报告会让人误以为是完整的 N 轮。
每跑完一格往 `<root>/status.tsv` 追一行：`round op side switch rc elapsed_s success
failed replay_fallback no_cudagraph capture_poisoned`。README 要求必查的三个标记就在
这张表里，跑的时候就能看见它们从 0 变成非 0，不用等结束再 grep——事后 grep 只在有人
想起来的时候才发生。每格另有 `CELL_TIMEOUT`（默认 2400 秒）兜底，超时记 `rc=124` 并打
`!!! CELL_TIMEOUT`，不会让一格卡死拖住整批。
全程还采一份 `<root>/telemetry.tsv`：
```
timestamp index sm_clock_mhz mem_clock_mhz temp_c power_w util_pct
2026-09-10T07:41:12 7 1888 2500 36 477.68 87
```
列在 cuda 与 musa 上完全一致（`nvidia-smi --query-gpu` 与 `mthreads-gmi -q --json`
各自解析后归一），所以两台机器的 campaign 可以并排读。理由很直接：六轮 A/B 声称的是
0.01% 量级的单侧噪声，**降频和热漂移能移动比这大得多的延迟，而且在 run.log 里不留
任何痕迹**——报告照样干净。`TELEMETRY_INTERVAL`（默认 5 秒）设 0 关闭；采样器缺失或
没权限时 `telemetry.py` 安静退出并把原因写进 `telemetry.err`，不影响测试本身。
第 1 轮 A/B 跑完后，脚本比两侧 `ttgir/` 的指纹（相对路径 + 内容）。**逐字节相同就
跳过这个算子**，并打 `!!! SWITCH_NO_IR_DIFF op=... switch=...`：这个开关没改变该算子的
生成代码，剩下 N-1 轮测的全是噪声，最后还会报成一个"无差异"的结论。先查开关名拼写
与它在被测源码里的读取点；确属只影响运行时、不影响 IR 的开关，用
`SWITCH_ALLOW_NO_IR_DIFF=1` 放行。
报告分开给两种离散度，它们回答不同的问题：
| 指标 | 含义 |
|---|---|
| 逐轮区间 | N 轮各自 delta 的 min~max，说明**判定**稳不稳 |
| 单侧噪声 | 同一侧 N 次延迟的极差，说明**机器**吵不吵 |
| 符号不稳行数 | delta 在轮次间改变符号的 shape 数，这些行的方向不可结论 |
已有产物可以单独重出报告，目录形态是 `<root>/r<k>_<A|B>/run.log`：
```bash
python batch_summary.py --ab-rounds runs/ab_repeat_XXX/topk --label topk
```
NV 上验证过这条路径：`router_gemm` 六轮把逐轮区间收窄到 -16.6% ~ -16.2%、单侧
噪声 0.4%，把单对观测升级成了结论。

clocks ramping, another process arriving. Repeating the call and taking the

unroll that many calls into a captured graph so host launch overhead drops
out, then time independent replays. Upstream is used verbatim on CUDA; this
exists because upstream names torch.cuda directly and so cannot run anywhere
else.
Replay timings go to _summarize_statistics as a plain list of floats, which
is what both do_bench and upstream's do_bench_cudagraph pass: this fork's
helper runs Python's statistics module over them, so wrapping them in a
tensor makes "mean" raise and makes a quantile request return tensors that
later fail to serialize.

This plugin runs at import time — before any test module imports flag_gems —
detects the vendor via torch (no subprocess), and sets GEMS_VENDOR so
device_finder takes its env fast-path (`_get_vendor_from_env`) and never
reaches the hang-prone subprocess probe. No change to the FlagGems repo.
Side effect: get_device_properties initializes the CUDA context very early in

"""Narrow compatibility fixes for the frozen MUSA product corpus.
Several upstream FlagGems tests gate themselves on ``torch.cuda.is_available()``
even though the code under test runs on any accelerator FlagGems dispatches to.
On MThreads those guards skip the test instead of exercising the operator, which
turns a working path into a verdict of "not measured".
Every override here is pinned to one file and one exact skip reason, applies
only when FlagGems has dispatched to the MThreads vendor, and is only added
after the unskipped test was observed to pass on the device.
Two files were probed on S5000 and deliberately left out, because their guards
are not stale:
- ``test_cutlass_scaled_mm.py`` gates on vLLM as well as CUDA, so removing the
guard would raise on the missing dependency instead of measuring anything.
- ``test_grid_sample.py`` builds its inputs through a helper whose device
argument defaults to the literal ``"cuda"``. Its guard is consistent with its
own body: unskipped, all 90 collected cases fail in ``aten::empty`` on a CUDA
backend that does not exist here. Making that file portable means editing
upstream test source, which is outside what a compatibility plugin may do.

nothing leaves `triton.testing.do_bench` in place and records `timer=direct`.

# convert_layout，42 个 shape 里却有 17 个在两次同等有效的运行之间改变了 delta
# 的符号——那不是计时口径的问题（图捕获与 direct 的延迟比是 1.00x），是收益本身
# 落在零附近、单次测量给不出方向。多轮之后才谈得上"这个判定成立"。
#
# 口径：第 1 轮 A 侧 record autotune config，此后每一次运行（含 A 侧自己的后续
# 轮次）都 REPLAY_FROM 那一份。config 因此跨轮跨侧全部锁死，剩下的变量只有被测
# 开关与测量噪声。逐轮交替先后顺序，抵消单向漂移。

# A/B 对比：FlagTree RemoveLayoutConversions 增强关 vs 开，逐算子两轮。

# config 跑开，两侧只差 FLAGTREE_<VENDOR>_RLC_ENHANCE 这一个开关。产物沿用
# run_pytest.sh 的目录结构，所以每个算子恰好留下两份 run.log：

# 编译器开关无从谈起。不是"开关无作用"
# NO_ROWS 没有测量行 -> 先修可运行性，多半是 dtype

# S5000 MUSA RLC 产品验证 campaign
在 Moore Threads S5000 上，经由 FlagGems public dispatch，测量 FlagTree
`RemoveLayoutConversions`（RLC）增强对 32 个冻结 workload 的影响。
本目录只提供 campaign 层：契约、冻结、执行、判定、重记账。单算子插件、shape、
inventory 仍然复用仓库根目录的既有能力。
## 组成
| 文件 | 作用 |
|---|---|
| `manifest/musa-rlc-32-product-v1.json` | 冻结契约：源码提交、设备、cell、计时口径、32 个 workload |
| `prepare_musa_rlc_product.py` | 校验 manifest 与 `ops/inventory_main.csv`，冻结不可变 task matrix |
| `run_musa_rlc_product.py` | 串行执行 task matrix，产出逐 cell、逐 task、campaign 三级收据 |
| `run_pytest_musa_rlc_product.sh` | 单个算子单个 cell 的 worker，挂载根目录插件 |
| `reaccount_musa_rlc_topology.py` | 对已封存 run 按新口径重记账，不占用设备 |
| `tests/` | 上述四者的单元测试 |
根目录的 `_musa_benchmark_compat_plugin.py` 属于插件族，不在本目录。
## 三个 cell
| cell | `FLAGTREE_MUSA_RLC_ENHANCE` | phase mask | 含义 |
|---|---|---|---|
| `off` | 0 | — | 增强关闭的基线 |
| `mask0` | 1 | 0 | 增强开启但所有 phase 关闭；它的 topology 必须等于 `off`，否则控制面本身有问题 |
| `candidate` | 1 | 13 | 1a、2、3 启用，1b 未启用 |
`off` 记录 autotune config，`mask0` 与 `candidate` 回放同一套 config。回放回退即判定失败，
这样 A/B 之间的差异才收敛到编译器改动这一个变量。
## 跑法
```bash
python campaigns/musa_rlc_product/prepare_musa_rlc_product.py \
campaigns/musa_rlc_product/manifest/musa-rlc-32-product-v1.json \
--inventory-dir ops --selection canary --dry-run
```
`--dry-run` 只做校验与预算估算。去掉它并给出 `--output-root` 才会冻结 task matrix。
`--selection all` 需要 `--canary-receipt` 指向一份通过的 canary 收据。
执行：
```bash
python campaigns/musa_rlc_product/run_musa_rlc_product.py \
--manifest <frozen>/manifest.json \
--task-matrix <frozen>/task-matrix.json \
--build-root <flagtree build root> \
--flaggems <flaggems> --zl-bench <this repo> \
--worker campaigns/musa_rlc_product/run_pytest_musa_rlc_product.sh \
--output-root <run root>
```
runner 在开跑前校验：manifest 与 matrix 的哈希绑定、FlagTree/FlagGems/zl_bench 三处源码身份、
Triton 与 FlagGems 确实从冻结路径导入、设备可见数为 1、所有 benchmark 与 correctness 目标
在真实源码树里存在、设备当前没有其它进程。任何一条不成立就整批拒绝。
单元测试直接跑文件：
```bash
python campaigns/musa_rlc_product/tests/test_musa_rlc_product.py
python campaigns/musa_rlc_product/tests/test_reaccount_musa_rlc_topology.py
```
## 判定
| 类 | 含义 |
|---|---|
| G | 正确，convert topology 下降，且双执行顺序下均稳定提速 ≥5% |
| C | 正确，topology 下降，但收益不足 5% |
| B | 正确，但 candidate 没有减少被测算子的 convert topology |
| R | 正确，但双顺序稳定退化 ≤ -3% |
| K | candidate 特有的正确性失败 |
| X | 不支持、超时、harness 失败，或同配置回放被破坏 |
只有 topology 相对 incumbent 下降时才追加反向顺序计时。convert 数下降不等于变快，
这一点在本 campaign 内已有反例。
## 三条口径边界
**convert 计数只算被测算子。** benchmark 调用会先构造一次输入再在计时区内反复执行算子。
把所有执行过的 kernel 都计入，会把输入构造 kernel 里消掉的 convert 算成收益，而计时器
根本观测不到它。因此每个 dump 的 TTGIR 都与 `index.tsv` 的 launch 数关联，只有 launch
数超过 `measured_launch_floor` 的变体才计入。未收敛总数与被排除文件保留在收据里；
无法与 index 关联的 cell 判为 X，而不是相信一个界定不了的 topology 声明。
**correctness 只跑该 workload 实际测量的变体。** 以整个测试文件为粒度，会让无关变体
决定被测算子的结论。workload 可以钉 node id 或 `-k` 选择器，两者互斥，且任何收窄都必须
写明理由。完整 argv 落在收据里。
**目标在开跑前解析。** inventory 可能落后于固定的 FlagGems 提交，例如上游把一个 benchmark
文件拆成多个。这类任务过去只在 worker 前置检查里静默失败，留下空日志。现在 runner 会
对真实源码树解析全部目标，workload 可以声明 inventory 里没有的目标但必须给出理由，
worker 的每个前置检查失败时自报名称。
## 不属于本 campaign 的结论
一次 terminal 的 campaign 只证明：该冻结语料在该设备该提交下的 dispatch 正确性、
layout topology 响应、以及同契约下的 native-event 延迟。它不证明跨厂商正确性、
性能对等、CI 状态，也不构成打开生产默认开关的依据。manifest 的
`production_default_policy` 固定为 `unchanged-off`。

"""Re-account a sealed MUSA RLC run under measured-operator convert scoping.
The sealed campaign counted every executed kernel's ``ttg.convert_layout`` ops,
including the kernels a benchmark launches once to build its inputs. Those sit
outside the timed region, so a candidate could be credited with a topology
reduction that no timer could ever observe.
This tool re-reads the sealed TTGIR dumps and their launch index, recomputes the
convert counts scoped to repeatedly launched kernels, and re-runs the campaign
classifier. It never writes inside the sealed run.
A re-accounted verdict can only demote a topology claim. Promoting a task to G
or C needs reversed-order timing, which a sealed run only holds for tasks that
already showed a reduction, so a newly appearing reduction is reported as X for
missing round-b evidence rather than guessed.
