PetscKokkosInitializeCheck

Initialize Kokkos if it has not already been initialized

Synopsis

PetscErrorCode PetscKokkosInitializeCheck(void)

Not Collective

Notes

Called internally before PETSc invokes any Kokkos-based functionality. The first call initializes Kokkos using either the user’s command-line options or defaults derived from PETSc’s device configuration; subsequent calls are no-ops.

PETSc will call Kokkos::finalize() itself during PetscFinalize() only if it was the one that initialized Kokkos in this process.
