private subroutine comms_scatterv_int_1(array, localcount, rootglobalarray, counts, displs)

Scatter integer data from root node (array of rank 1)

Arguments

Type IntentOptional AttributesName
integer, intent(inout), dimension(:):: array

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

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

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

how data should be partitioned, see MPI documentation or function comms_array_split
integer, intent(in), dimension(num_nodes):: displs
