comms_no_sync_scatterv_int_3 Subroutine

private subroutine comms_no_sync_scatterv_int_3(array, localcount, rootglobalarray, counts, displs, error, comm)

Scatter integer data from root node (array of rank 3)

Arguments

Type IntentOptional Attributes Name
integer, intent(inout) :: array(:,:,:)

local array for getting data
integer, intent(in) :: localcount

localcount elements will be fetched from the root node
integer, intent(inout) :: rootglobalarray(:,:,:)

array on the root node from which data will be sent
integer, intent(in) :: counts(0:)

how data should be partitioned, see MPI documentation or function comms_array_split
integer, intent(in) :: displs(0:)
type(w90_error_type), intent(out), allocatable :: error
type(w90_comm_type), intent(in) :: comm
