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/interface/matregis.c

Fri, 19 May 2023 16:10:28 +0000

Add `MATDIAGONAL` and `PCMatSetApplyOperation()``MATDIAGONAL` (`MatCreateDiagonal()`) is an interface formanipulating a diagonal matrix as a `Vec`, in particular supportingno-copy modification of the diagonal and inverse diagonal via`MatDiagonalGetDiagonal()`, `MatDiagonalRestoreDiagonal()`,`MatDiagonalGetInverseDiagonal()`, and`MatDiagonalRestoreInverseDiagonal`().`PCMatSetApplyOperation()` and `PCMatGetApplyOperation()`support using all the linear operators currently defined by a `Mat`(`MatMult()`, `MatMultTranspose()`, `MatMultHermitianTranspose()`,`MatSolve()`, `MatSolveTranspose()`) as the operation of `PCApply()`for a `PCMAT`. The advantage over a `PCSHELL` is that the otheroperations (`PCApplyTranspose()`, `PCMatApply()`) are automaticallyinferred.These tools help make it easier to route operations like`VecPointwiseMult()` and `VecPointwiseDivide()` through`KSPSolve()` to avoid handling diagonal matrices as a specialcase (a pattern that is going to be removed from `MATLMVM`).

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/interface/matregis.c
