Hi,

I'm running my ParFUMized version of my code at the taub cluster at uiuc.
Each node contains 12 processors. I'm running in one node, with option +p2,
but I have the feeling that the code is running in a single processor. My
clue is that this is related with this "warning"

Charm++> Running on MPI version: 2.2 multi-thread support: 0 (max supported:
-1)


My question is:

Where it is the issue? Is it on how MPI was compiled or on how charm++ was
compiled or on how I call charmrun?
Thanks
Fernando





Here it is the full call.

[fstump2@taubh2
io]$ ../yafeq/build/debug/yafeq/charmrun ../yafeq/build/debug/yafeq/pfem.out
+p2

Running on 2 processors: ../yafeq/build/debug/yafeq/pfem.out
charmrun> /usr/bin/setarch x86_64 -R mpirun -np 2
../yafeq/build/debug/yafeq/pfem.out
