- Logic to calculate the kernel index in AVX512
DGEMMT SUP framework is incorrect.
- The granularity for workload distribution along N
dimension is NR(8), whereas current logic to pick
diagonal kernel assumes the granularity to be MR (24).
- To Fix this, the logic to determine the kernel index is
changed, instead of relying solely on n_offset, the kernel
index is derived depending on distance from the diagonal.
- If distance from diagonal is greater than
LCM of (MR and NR) - NR, that that means the current micro
panel is not a diagonal micro panel.
- If the micro panel is a diagonal micro panel, then the
distance from diagonal is equal to the M dimension for
initial full GEMM region or empty region of diagonal
kernel. This info can be used to determine the kernel index.
