Hello,<br><br>I followed the instructions on the FAQ page to configure and compile openmpi so that it should work with Torque.<br>./configure --with-tm=/usr/local --prefix=/usr/local<br>The option --disable-server was used to configure torque on the compute nodes.<br>
I got openmpi compiled without any error message on the head and compute nodes.<br><br>I can use<br>$ mpirun -np 2 --host node1,node2 a.out<br>to run parallel programs without any problem.<br><br>However,  when I submit the following script with qsub<br>
<br>____________________________________________________________________<br>#!/bin/sh<br>#<br>PBS -N Test<br>PBS -o /home2/user2/test.sh.o<br>PBS -l nodes=8<br>mpirun /home2/user2/a.out  # a.out simply prints out # of procs and its ID<br>
____________________________________________________________________<br><br>I got the following output and error messages.<br><br>Output:<br>N. of procs = 1, proc ID = 0<br><br>Error messages:<br>/var/spool/torque/mom_priv/jobs/<a href="http://198.my_head_node.SC">198.my_head_node.SC</a>: 3: PBS: not found<br>
