Folks;
I have the following code setup. The sensorList is an array of
ints of size 1. The value it contains is 1. My comm world size is 5. The call
to MPI_Barrier fails every time with error "invalid communicator". This code is
pretty much copied out of a text book. I must be doing something wrong. I just
don't see it. Can anyone else spot my error? I am using v2.01 on red hat 6.5.
Thanks
Rick
MPI_Comm_group(MPI_COMM_WORLD, &worldgroup);
MPI_Group_incl(worldgroup, 1, sensorList, &sensorgroup);
MPI_Comm_create(MPI_COMM_WORLD, sensorgroup, &sensorComm);
MPI_Barrier(sensorComm);
