[mpich-discuss] MPI_Group_incl

[Norman Lo]

Hi,

For the function MPI_Group_incl:

int MPI_Group_incl ( MPI_Group group, int n, int *ranks, MPI_Group 
*group_out );

Does the parameter ranks need to be an ordered list ? I am getting some 
erratic behavior randomly in the code if ranks is out of order.

Thank you,

Norman
