I’m currently working in an environment where I cannot use SSH to launch child processes.  Instead, the process with rank 0 skips the ssh_child function in plm_rsh_module.c and the child processes are all started at the same time on different machines.  Coordination is done with static jobids and ports.  I have sucessfully modified the code to get the hello_c example working.  However, I’m having problems with inter-process communication when using MPI_Bcast.  Is there something else that I’m obviously missing?
