    I have a hybrid MPI/UPC application that I'm having trouble running.   
    When I run my app, compiled with the conduit set to udp, the app/ 
    upcrun spawns the correct amount of processes/threads but each proc/ 
    thread doesn't see each other and proceeds like a serial job.
    I've compiled the same app using the mpi conduit and have been able  
    to get MPI procs == UPC Threads.  I've been poking around upcrun,  
    etc ... to see if I can figure out what's going on but I'm stuck  
    right now, it doesn't help that I don't know any perl.
    Here's some info on my setup:
    MPI - LAM 7.1.3
    BUPC - 2.4
    Compilers - GCC 3.4.5 (MPI and BUPC were compiled with the same  
    BUPC translator - local one compiled with the above compiler
    OS - CentOS (I think) on AMD opterons
    any help would be greatly appreciated.
    ps do you guys plan to extend support for the other Myrinet  
    interconnect ... I think it's called mx or something like that.
