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/impls/sell/mpi/mmsell.c Thu, 09 Jan 2020 04:05:36 +0000 Hong Zhang <hongzhang@anl.gov> http://opengrok.kc2vjw.com:8080/history/petsc/src/mat/impls/sell/mpi/mmsell.c#31d78bcd2b98084dc1368b20eb1129c8b9fb39fe Merge branch 'jacobf/2022-12-10/petscerrorcode-nodiscard' into 'main'Feature: Non-discardable PetscErrorCodeSee merge request petsc/petsc!5923 List of files: /petsc/src/mat/impls/sell/mpi/mmsell.c Thu, 02 Feb 2023 20:39:47 +0000 Satish Balay <balay@mcs.anl.gov> http://opengrok.kc2vjw.com:8080/history/petsc/src/mat/impls/sell/mpi/mmsell.c#3ba1676111f5c958fe6c2729b46ca4d523958bb3 Make PetscErrorCode a non-discardable enum List of files: /petsc/src/mat/impls/sell/mpi/mmsell.c Sat, 10 Dec 2022 18:29:11 +0000 Jacob Faibussowitsch <jacob.fai@gmail.com> http://opengrok.kc2vjw.com:8080/history/petsc/src/mat/impls/sell/mpi/mmsell.c#2f91b18a518e38a1bb5cc181d7f42327698cc9f1 Merge branch 'jacobf/2022-11-08/remove-petsctable' into 'main'Remove PetscTableSee merge request petsc/petsc!5819 List of files: /petsc/src/mat/impls/sell/mpi/mmsell.c Wed, 23 Nov 2022 18:04:01 +0000 Satish Balay <balay@mcs.anl.gov> http://opengrok.kc2vjw.com:8080/history/petsc/src/mat/impls/sell/mpi/mmsell.c#c76ffc5fd3d97b0269353f2b54a8f561b4411450 Use PetscHMapISet() in place of PetscHMapISetWithMode(INSERT_VALUES) as the intent is clearer List of files: /petsc/src/mat/impls/sell/mpi/mmsell.c Mon, 21 Nov 2022 13:56:00 +0000 Jacob Faibussowitsch <jacob.fai@gmail.com> http://opengrok.kc2vjw.com:8080/history/petsc/src/mat/impls/sell/mpi/mmsell.c#eec179cf895b6fbcd6a0b58694319392b06e361b - Replace PetscTable with PetscHMapI.- Rename: - PetscTableCreate() -> PetscHMapICreateWithSize() - PetscTableFind() -> PetscHMapIGetWithDefault() - PetscTableAdd() -> PetscHMapISetWithMode() List of files: /petsc/src/mat/impls/sell/mpi/mmsell.c Tue, 08 Nov 2022 13:38:09 +0000 Jacob Faibussowitsch <jacob.fai@gmail.com> http://opengrok.kc2vjw.com:8080/history/petsc/src/mat/impls/sell/mpi/mmsell.c#061e922f3926be00487707c73b78dd3d40309129 Merge branch 'jacobf/2022-09-21/2-bike-2-shed' into 'main'Feature: Bicycle Storage Facility 2See merge request petsc/petsc!5661 List of files: /petsc/src/mat/impls/sell/mpi/mmsell.c Thu, 22 Sep 2022 02:09:24 +0000 Satish Balay <balay@mcs.anl.gov> http://opengrok.kc2vjw.com:8080/history/petsc/src/mat/impls/sell/mpi/mmsell.c#d71ae5a4db6382e7f06317b8d368875286fe9008 source code format changes due to .clang-format changes List of files: /petsc/src/mat/impls/sell/mpi/mmsell.c Wed, 21 Sep 2022 21:15:28 +0000 Jacob Faibussowitsch <jacob.fai@gmail.com> http://opengrok.kc2vjw.com:8080/history/petsc/src/mat/impls/sell/mpi/mmsell.c#b7124133bcd51a3ab3000e5ce6fd55508e9e5602 Merge branch 'jacobf/2022-09-17/slimmer-petscobject' into 'main'Feature: Slimmer PetscObjectSee merge request petsc/petsc!5649 List of files: /petsc/src/mat/impls/sell/mpi/mmsell.c Tue, 20 Sep 2022 13:14:27 +0000 Satish Balay <balay@mcs.anl.gov>
