PetscInt#
PETSc type that represents an integer, used primarily to represent size of arrays and indexing into arrays. Its size can be configured with the option –with-64-bit-indices to be either 32-bit (default) or 64-bit.
Notes#
For MPI calls that require datatypes, use MPIU_INT
as the datatype for PetscInt
. It will automatically work correctly regardless of the size of PetscInt.
