“假设 cache line 为 32B。待访问数据大小为 64B,地址在 0x80000001,则需要占用 3 条 cache 映射表项;若地址在 0x80000000 则只需要 2 条。内存对齐变相地提高了 cache 命中率。”假定kernel一次计算执行 4×4 大小的block, 根据MMult_4x4_7.c (https://github.com/flame/how-to-optimize-gemm/blob/m...
Extend to Training: Modify the CNN_CUSTOM model to fully integrate the custom kernel into the training process. This would require adding backward pass support via torch.autograd.Function.

The WMMA instruction optimizes the scheduling of data movement and peak math operations with minimal VGPR access by providing source data reuse and intermediate destination data forwarding operations without interruption. The regular patterns experienced in matrix operations enable WMMA instructions to reduce...
