<A HREF="../Vec/PetscOffloadMask.html#PetscOffloadMask">PETSC_OFFLOAD_UNALLOCATED</A> - no memory contains valid matrix entries; NEVER used for vectors
<A HREF="../Vec/PetscOffloadMask.html#PetscOffloadMask">PETSC_OFFLOAD_GPU</A> - GPU has valid vector/matrix entries
<A HREF="../Vec/PetscOffloadMask.html#PetscOffloadMask">PETSC_OFFLOAD_CPU</A> - CPU has valid vector/matrix entries
<A HREF="../Vec/PetscOffloadMask.html#PetscOffloadMask">PETSC_OFFLOAD_BOTH</A> - Both GPU and CPU have valid vector/matrix entries and they match
<A HREF="../Vec/PetscOffloadMask.html#PetscOffloadMask">PETSC_OFFLOAD_VECKOKKOS</A> - Reserved for Vec_Kokkos. The offload is managed by Kokkos, thus this flag is not used in Vec_Kokkos.
