This problem was solved by correcting LDAP to allow ssh automatic authentication between *all* the nodes (instead of just between the master node and each worknode). This wasn't required for a plain mpiexec but it is when using qsub.

torque  4.1.7

mpich2 1.5 with hydra


Hi all,

I am trying to integrate a working mpi job script to submit using torque.
I have built a machinefile to match the nodes I request (n23,n24,n25 and n26 in this case). This is the beginning of my submission script:

#!/bin/sh
#PBS -N run_conf11_jul_aug
##PBS -W x="NACCESSPOLICY:SINGLEJOB"
#PBS -l nodes=n23:ppn=8+n24:ppn=8+n25:ppn=8+n26:ppn=8
#PBS -k oe
#PBS -q multiple

(...)
mpiexec -envlist _CONFIGURATION_ -f machinefile -l -np 32 ../bin/getm_prod_IFORT13.0060x0085


After mpiexec being called I get this error:


Permission denied, please try again.
Permission denied, please try again.
Received disconnect from 10.1.0.25: 2: Too many authentication failures for be_user
Permission denied, please try again.
Permission denied, please try again.

Permission denied, please try again.
Received disconnect from 10.1.0.24: 2: Too many authentication failures for be_user
Received disconnect from 10.1.0.26: 2: Too many authentication failures for be_user


I can ssh to any of the nodes with no problem and the same scripts works when not using qsub.

Any ideas please?
