ISCreateStride

Creates a data structure for an index set containing a list of evenly spaced integers.

Synopsis

#include "is.h"   
int ISCreateStride(MPI_Comm comm,int n,int first,int step,IS *is)
Collective on MPI_Comm

Input Parameters

comm - the MPI communicator
n - the length of the index set
first - the first element of the index set
step - the change to the next index

Output Parameter

is -the new index set

Notes

When the communicator is not MPI_COMM_SELF, the operations on IS are NOT conceptually the same as MPI_Group operations. The IS are the distributed sets of indices.

Keywords

IS, index set, create, stride
