pto-isa-matmul-l2-schedule
pto-isa-matmul-l2-schedule is an MLOps & model serving skill for AI agents, published by hw-native-sys in the pto-isa repository on GitHub. Skillspace rates pto-isa-matmul-l2-schedule D (62/100) and it passed the safety scan; the rating is based on static analysis only.
PTO-DSL matmul L2-reuse scheduler for Ascend A2/A3: persistent-block GEMM with N-group swizzle along the inner M walk and M-direction zigzag at N-group boundaries. Captures the tile-id math, the CANN platform_config- driven swizzleCountN budget (with the 32 MiB safety-ratio cliff), the DN-B layout note, the runtime wiring, and the verification path against torch_npu. Use when tuning a matmul-shaped kernel that profiles as L2-bound, porting the swizzle/zigzag schedule to a new persistent-block kernel, choosing swizzleCountN for a new SoC, or deciding between the manual SPMD-static baseline and this persistent + swizzle schedule. Scoped to one schedule recipe — add a separate skill for other PTO-ISA performance patterns (vector reduce, flash-attention scheduling, etc.).
