- Main kernel is of size 24x8 and the associated fringe kernels
added are
- 24x7m, 24x6m, 24x5m, 24x4m, 24x3m, 24x2m, 24x1m
- 24x8, 24x7, 24x6, 24x5, 24x4, 24x3, 24x2, 24x1
- 16x8, 16x7, 16x6, 16x5, 16x4, 16x3, 16x2, 16x1
- 8x8, 8x7, 8x6, 8x5, 8x4, 8x3, 8x2, 8x1
- For fringe kernels, 24x? kernel handles 16 < m_remainder < 24
16x? kernel handles 8 < m_remainder <= 16
8x? kernel handles 0 < m_remainder <= 8
- Added a function 'bli_zen4_override_gemm_blkszs' to override
blocksizes and kernels to be used for SUP for supported storage
schemes.
- Updated the zen4 config to enable these kernels in zen4 path.
- Thresholds are yet to be derived.
- Updated CMakeLists.txt with DGEMM SUP kernels for windows build.
Kernel-specific details:
- K-loop is unrolled by 8 times to facilitate prefetch of B.
- For every load of one column of A, the corresponding column in
next panel of A is prefetched with T1 hint.
- One column of C is prefetched with T0 hint per iteration of LOOP2.
- TAIL_NITER is derived to be 3.
- For every unroll of k-loop, one row of B is prefetched with T0 hint.
- C-prefetching for row-storage is yet to be added.
- B-prefetching for col-storage is yet to be added.
- Support for C transpose is yet to added.
