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.

# 多轮 A/B：同一对比在 N 轮独立进程里各跑一次，逐 shape 取轮次中位。
|
||
#
|
||
# 为什么需要它：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。
|
||
#
|
||
# 用法：
|
||
# SWITCH=FLAGTREE_MUSA_RLC_ENHANCE OPS="topk masked_select" ROUNDS=6 \
|
||
# ZL_BACKEND=musa FLAGGEMS_DIR=/path/to/FlagGems bash ab_repeat.sh
|
||
#
|
||
# OPS 元素为 OP 或 OP:OP_FILE（省略时 OP_FILE=OP）。
|
||
# SWITCH 是被测环境变量，A 侧设 0、B 侧设 1。
|
||
#
|
||
# 对比轴有效性由脚本自己查：第 1 轮 A/B 跑完后比两侧的 ttgir 指纹，完全一致说明
|
||
# 这个开关在这个算子上没改变任何生成代码——继续跑满 N 轮只会得到一个"无差异"的假
|
||
# 结论（同 ab_fold_test.sh 的告诫）。这类算子默认跳过；开关确实只影响运行时而不影响
|
||
# IR 时，用 SWITCH_ALLOW_NO_IR_DIFF=1 放行。
|
||
#
|
||
# 产物：runs/ab_repeat_<开关>_<时间戳>/<op>/r<k>_<A|B>/，跑完对每个算子调用
