get_local_size Subroutine

private subroutine get_local_size(n_global, comm, start, count, is_even)

Computes local portions of data based on global count and position inside grid communicator

Arguments

Type IntentOptional Attributes Name
integer(kind=int32), intent(in) :: n_global

Global number of points
type(MPI_Comm), intent(in) :: comm

Grid communicator
integer(kind=int32), intent(out) :: start

Local start
integer(kind=int32), intent(out) :: count

Local count
logical, intent(out) :: is_even

Is data evenly distributed across processes
