After I launch the processes I can send a message to the assembler, the one for which I was having problems. It is still running a fake process, which prints out a message to the terminal when it gets an MPI message. I see the terminal message on the rank 0 process, which I'm running interactively. Another processes sends 2 messages to the assembler. The sender continues to operate, indicating mpi.send completed. However, I never see any messages from the assembler that it got a message. A different process then sends a message to the assembler, and that sender then hangs. Ross Boylan
