I am wanting to upgrade a cluster from Fedora 4 to Fedora 6, but am  
hung up on the OSC mpiexec part.

I have torque  2.1.6-1 from the Fedora repo installed.

mpiexec compiles fine, I used
./configure ---with-default-comm=mpich-p4

my script, dompi is basically

/path/to/mpiexec ./app

I submit the dompi script, with
qsub -l nodes=nodeX dompi

on the node I upgraded (node5), I get in the error log
mpiexec: Error: get_hosts: pbs_connect: no error.

and this is because pbs_connect(0) in  get_hosts.c returns -1 for me  
on this node, I guess it's supposed to return the number of available  

It still works on the other ones though.

Some sort  of host resolution error? Everything seems fine to me.
