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.
