ulimit of programs run by mpiexec?

[Aquarijen]

Hey Garrick,
Thank you for your help!
I added a default memory size of 2gb to the queue and it really didn't
do anything regarding the stack size.  If I do something silly ;) and
launch a shell to launch mpiexec, the program only runs on one node...

Maybe I'm not doing this right?
I did:
set server resources_default.pmem = 2gb

Should I set something else ?

or should I give up and set the system ulimit higher? :}

Thanks so much!
Jen
