Synopsis
typedef enum {PETSC_OFFLOAD_UNALLOCATED=0x0,PETSC_OFFLOAD_CPU=0x1,PETSC_OFFLOAD_GPU=0x2,PETSC_OFFLOAD_BOTH=0x3} PetscOffloadMask;
PETSC_OFFLOAD_UNALLOCATED - no memory contains valid matrix entries; NEVER used for vectors
PETSC_OFFLOAD_GPU - GPU has valid vector/matrix entries
PETSC_OFFLOAD_CPU - CPU has valid vector/matrix entries
PETSC_OFFLOAD_BOTH - Both GPU and CPU have valid vector/matrix entries and they match
