having trouble with running a hybrid MPI/UPC application using the udp conduit

• Previous message: Mercy Dunn: "parlor"

Hi,

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  
compilers)
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.
