Description

@Parxd

Example 1 for GEMM 01_gemm_global_reg crashes during kernel for default problem size:

  • M = 1024
  • N = 1024
  • K = 2048
  • TileM = 256
  • TileN = 128
  • TileK = 64

System:
OS: Ubuntu 24.04.2
Device: RTX 3070 Mobile (SM86)
Driver: 560.35.03
CUDA Version: 12.6

Output:

kThreads: 128
RegA: RowMajor(16, 16)
RegB: ColMajor(16, 8)
RegC: RowMajor(16, 16)
IteratorA: numel = 524288, ChunkShape = (256, 64), stripe count = (1, 32)
IteratorB: numel = 262144, ChunkShape = (64, 128), stripe count = (32, 1)
