testbed_swapAB

Testbed for comparing swapAB vs normal matmul execution.

swapAB is an internal optimization where:

• A and B operands are swapped inside the kernel
• The output C tile is transposed on write-out
• The final result C[M,N] should be identical to the normal kernel

Both kernels compute: C[M,N] = A[M,K] @ B[N,K]^T The swapAB version just does it via: (B @ A^T)^T stored transposed = A @ B^T

Functions

• ​test_matmul_sm90_swapAB_comparison: Compare matmul results between normal execution and swapAB execution.
• ​test_matmul_sm90_swapAB_comparison_v2: Compare matmul results between normal execution and swapAB execution.
