I am assuming all the processes are running on a single SMP? Not sure if
you have tried it but you may want to set the mpool_sm_max_size to
something other than the default 512MB, since you seem to be using
shared memory?

My guess is that this is similar to the last post: you are
oversubscribing the nodes so heavily that the OS is running out of
some resources (perhaps regular or registered memory?) such that Open
MPI is unable to setup its network transport layers properly.

Hi,
I am using openmpi 1.2.3 under ia64 machine and uses pbs job
scheduler. I can successfully run 100 processes on 16 cpus, but I got
an error If run 200 processes on the same number of cpus. The error
is :
PML add procs failed
--> Returned "Temporarily out of resource" (-3) instead of
"Success" (0)
Please help.
Regards,
Clement
