Here is a v1.6 port of what was committed to the trunk. Let me know if/how it
works for you. The option you will want to use is:
mpirun -mca opal_set_max_sys_limits stacksize:unlimited
or whatever number you want to give (see ulimit for the units). Note that you
won't see any impact if you run

I think I was excited too soon :). Increasing stacksize does help if I
run a job in a dedicated server. Today I tried to modify the cluster
(/etc/security/limits.conf, /etc/init.d/pbs_mom)
I should really have asked earlier. Thanks for all the helps.

Ok, so your problem is identified as a stack size problem. I went into

First, it seems you can increase your stack size as "ulimit -s

Hi folks,
I am sorry if this question had been asked before, but after ten days of
searching/working on the system, I surrender :(. We try to use mpirun to
run abinit (abinit.org) which in turns will call an input file to run
some simulation. The command to run is pretty simple
$ mpirun -np
