Latency by recipe

CPUaccelerator

Median of 10 timed runs after 3 discarded warmups. Hover a bar for variance and artifact size.

Speed against numerics

CPUaccelerator

Marker area scales with artifact size. Cosine is a numerics check against the fp32 PyTorch reference, not task accuracy — a model can hold cosine 0.999 and still fail on the slice that matters.

Repeatability

Recipes measured more than once on this unit, in separate sessions. This is the weakest useful form of the check — the real one runs the same recipe on two physical units of the same SKU, and we have one machine. Agreement here cannot catch a defect in the methodology that both runs share; it can only catch drift.

Recorded failures

Kept rather than hidden. A recipe that cannot lower is a fact about the toolchain, and it is what teaches the static filter not to propose it again.

unknown lowering failure

the runtime aborted the process (SIGABRT). This is a delegate-level crash, not a Python exception. Last output: l"(%arg1, %0) <{transpose_lhs = false, transpose_rhs = false}> : (tensor<1x128x1xf32>, tensor<768x768xf32>) -> tensor<1x128x768xf32>
