get_local_size Subroutine

private subroutine get_local_size(n_global, comm, start, count, start_to_keep, size_to_keep)

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

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

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

Local count
integer(kind=int32), intent(in), optional :: start_to_keep

Start to keep in case of user defined decomposition
integer(kind=int32), intent(in), optional :: size_to_keep
