This PR adds CUDA and HIP support to FSAI according to a static pattern generation algorithm. The resulting method can also be used as a preconditioner for BoomerAMG. A detailed list of changes is given below: * Add par_fsai_device.c * Add hypre_FSAIApply * Add function to dump local linear systems in dense format * Implement static FSAI pattern computation via powers of A * Improve filtering of candidate pattern * Improve local linear systems extraction * Add option for a 125pt matrix (27pt squared) * Add options to control sizes of the memory pools with umpire * Add hypre_GpuProfiling calls * Improve candidate pattern truncation times * Add max_nnz_row member and its private and public functions to FSAI * Use max_nnz_row in FSAISetupDevice * Add num_levels member and its private and public functions to FSAI * Add threshold member and its public/private functions to FSAI * Expose FSAI algorithm type to BoomerAMG * Expose options to control FSAI setup * Add cuSOLVER variables and calls * Add batched dense linear solver calls to FSAI * Improve execution time for generating random numbers * Show FSAI parameters when amg_print_level >= 1 * Improve output of FSAIPrintStats * Implement warp calls * Add hypre_mask type and hypre_ballot_sync wrapper function * Add hypre_popc and hypre_ffs wrapper functions * Implement warp_allreduce_max calls * Change: hypreDevice -> hypre_*Device * Add rocSOLVER calls * Apply astyle * Remove redundant line |
