Tue, 05 Mar 2024 00:49:41 +0000

Add SELLHIP- The HIP kernels are converted directly from their CUDA version- AMD GPUs and NVIDIA GPUs use different warp sizes. We set the warp size to 64 by default for AMD GPUs to faciliate compile-time code optimization List of files: /petsc/src/mat/tests/ex5.c

90d2215b4f5b865a0e7953289703ce9072a42621 - Add the load-balancing kernel for MatMultAdd_SeqSELL and fine tune the heuristic

Tue, 12 Jan 2021 02:45:55 +0000

Add the load-balancing kernel for MatMultAdd_SeqSELL and fine tune the heuristicKernel7 is significantly slower than kernel9x for the following two cases:- nrows is too small. Kernel7 uses 2 threads per row (assuming sliceheight=16), it does not fully utilize the GPU if nrows < 100K.- maxslicewidth is too big.Thanks-to: Peng Wang List of files: /petsc/src/mat/tests/ex5.c

2d1451d43b73a0495cd81c074cbc1e0206888947 - Initial commit for porting SELL to GPU

Thu, 09 Jan 2020 04:05:36 +0000

Initial commit for porting SELL to GPU- Add tiled SPMV and basic SpMVfor SeqSELL- Tested in serial- Offloadmask is used to determine when the matrix should be copied to GPU- Use different slice height for CUDA version- By checking the nonzerostate, PETSc can decide if the whole matrix need to be copied or just the values need to be copied- Make the convert function public so that the very slow MatConvert_Basic can be avoided sometimes. E.g. one can use a two-step convert method: AIJ->SELL,SELL->SELLCUDA instead of the direct convert AIJ->SELLCUDA- Make the FLOPS count for SELL same as that for AIJCUSPARSE.- MatDisAssemble is not needed.- Change slice height from 32 to 16 for GPU- To overlap communication with MatMult, VecScatterBegin() should be called before MatMult() for the diagonal part.- SLICE_HEIGHT is defined to be 32 to match the warp size of GPU. For other cases, it is still 8.Funded-by:Project: PETSc for GPUTime: 42 hoursReported-by:Thanks-to: List of files: /petsc/src/mat/tests/ex5.c
