One thing stands out right away: why are you specifying a hostfile? Did you remember to configure OMPI with --with-tm so we launch via Torque? If not, then you could hit issues as you are actually attempting to launch via ssh, which has implications on a Torque-based system.

Hi Team,
I am using Qlogic Infiniband and Openmpi-1.5.3. I can able to run the jobs by CLI without any issues, but when iam submitting over torque scheduler facing the below issue.
I am facing issue while submitting the jobs through Torque scheduler. Error file is attached
Overview of the problem:
node1.ibab.ac.in.5910Driver initialization failure on /dev/ipath (err=23)
--------------------------------------------------------------------------

PSM was unable to open an endpoint. Please make sure that the network link is
active on the node and the hardware is functioning.

Error: Failure in initializing endpoint

I gone through the link http://www.open-mpi.org/community/lists/users/2011/12/17888.php for solution, same followed but no luck.
I exported the value in my input submit script file as export PSM_SHAREDCONTEXTS_MAX=16, and submitted the job.
Sample inputfile is
#!/bin/bash

#PBS -N matmul
#PBS -l nodes=1:ppn=1
node=1

ppn=1
nprocs=`expr ${node} \* ${ppn}`
echo "--- PBS_NODEFILE CONTENT ---"

cat $PBS_NODEFILE
export PSM_SHAREDCONTEXTS_MAX=16

mpirun -np ${nprocs} --hostfile $PBS_NODEFILE /home/khan/a.out < /home/khan/iter

Please let me know I doing correct or not ? and suggest me for best out ?
Regards,
Bhagya Raju K
