ISCreateGeneral
Creates a data structure for an index set containing a list of integers.
Synopsis
int ISCreateGeneral(MPI_Comm comm,int n,const int idx[],IS *is)
Collective on MPI_Comm
Input Parameters
n | - the length of the index set
|
idx | - the list of integers
|
comm | - the MPI communicator
|
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 then
distributed sets of indices.
Keywords
IS, general, index set, create
