    Our cluster has a mix of machines, and  I need rank 0 in my application to run on a particular node that has the capabilities the controlling rank needs. Is there some way to do this I'm missing?

    There is no really good and simple way to do that.

    What I suggest is that you launch a batch file that manipulates the CCP_NODES environment variable to set it with your rank 0 node first. (e.g., using env var string substitution)
