Any ideas on why this isn't > working? It should work. However, we currently have some I/O forwarding problems which show up in some environments that will (hopefully) be fixed in the next release. As far as I know, the problem seems to happen mostly with non-mpi applications. Try running a simple mpi application, such as: #include <stdio.h> #include "mpi.h" int main(int argc, char* argv[]) { int rank, size; MPI_Init(&argc, &argv); MPI_Comm_rank(MPI_COMM_WORLD, &rank); MPI_Comm_size(MPI_COMM_WORLD, &size); printf("Hello, world, I am %d of %d\n", rank, size); MPI_Finalize(); return 0; } If that works fine, then it is probably our problem, and not a problem with your setup. Sorry I don't have a better answer :( Tim
