PetscOffloadMask#
indicates which memory (CPU, GPU, or none) contains valid data
Synopsis#
#include <petscdevicetypes.h>
typedef enum {
PETSC_OFFLOAD_UNALLOCATED = 0x0,
PETSC_OFFLOAD_CPU = 0x1,
PETSC_OFFLOAD_GPU = 0x2,
PETSC_OFFLOAD_BOTH = 0x3,
PETSC_OFFLOAD_VECKOKKOS_DEPRECATED = 0x100,
PETSC_OFFLOAD_KOKKOS = 0x100
} PetscOffloadMask;
Values#
PETSC_OFFLOAD_UNALLOCATED- no memory contains valid matrix entries; NEVER used for vectorsPETSC_OFFLOAD_GPU- GPU has valid vector/matrix entriesPETSC_OFFLOAD_CPU- CPU has valid vector/matrix entriesPETSC_OFFLOAD_BOTH- Both GPU and CPU have valid vector/matrix entries and they matchPETSC_OFFLOAD_KOKKOS- Reserved for Kokkos matrix and vector. It means the offload is managed by Kokkos, thus this flag itself cannot tell you where the valid data is.
Developer Note#
This enum uses a function (PetscOffloadMaskToString()) to convert to string representation so
cannot be used in PetscOptionsEnum().
