PETSC_MPI_THREAD_REQUIRED

the required threading support used if PETSc initializes MPI with MPI_Init_thread(). Deprecated, use PetscSetMPIThreadRequiredType()

Note

By default PETSC_MPI_THREAD_REQUIRED equals MPI_THREAD_FUNNELED when the MPI implementation provides MPI_Init_thread(), otherwise it equals MPI_THREAD_SINGLE
