Accelerate SVE128 SBGEMM/BGEMM
 2026-03-06 09:14:44 +01:00
Fadi Arafeh f30202b705 Accelerate SVE128 SBGEMM/BGEMM 
This accelerates SBGEMM/BGEMM by extending the existing 8x4 kernel to 8x8 (unrolling N by 8)

Not sure if it's a good idea to delete the previous 8x4 kernel?

Here are the speedups on single core Neoverse-V2 (SVE128) compared to prev state:

Per-shape speedup
  M=N=K=64: SBGEMM 1.164x (16.42%), BGEMM 1.133x (13.30%)
  M=N=K=128: SBGEMM 1.220x (22.02%), BGEMM 1.186x (18.56%)
  M=N=K=256: SBGEMM 1.241x (24.08%), BGEMM 1.235x (23.54%)
  M=N=K=512: SBGEMM 1.240x (23.95%), BGEMM 1.227x (22.75%)
  M=N=K=1024: SBGEMM 1.251x (25.11%), BGEMM 1.232x (23.23%)
  M=N=K=2048: SBGEMM 1.235x (23.47%), BGEMM 1.246x (24.64%)

Rajalakshmi Srinivasaraghavan 2283fcbbe7 POWER10: Reduce sgemm loop unrolling 
With GCC 14, unnecessary move and lxvp instructions appear when unrolling the inner loop for larger sizes.
Reducing the loop unroll factor restores performance to GCC 11.
