[torqueusers] Job stucks forever

[Abhishek Gupta]

Hi,
I am trying to submit a job. Once the job is submitted, it shows that 
the status is running while it is not doing anything. When I re-submit 
the job keeping the previously submitted job, the newer one runs fine 
and the old one still stays there as it is.
Could someone help?
The PBS script I am using is:

#!/bin/bash
############################################################
## 'man qsub' for additional information.
############################################################

#$ -v LD_LIBRARY_PATH=/usr/lib
#PBS -N MCRX
#PBS -l nodes=20
#PBS -l cput=36:00:00
#PBS -r n

export NPROCS=`wc -l $PBS_NODEFILE |gawk '//{print $1}'`

### The following statements dump some diagnostic information to
### the batch job's standard output.
echo The master node of this job is `hostname`
echo The working directory is `echo $PBS_O_WORKDIR`
echo The node file is $PBS_NODEFILE
echo "=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-"
echo This job runs on the following nodes:
echo `cat $PBS_NODEFILE`
echo "=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-"
echo This job has allocated $NPROCS nodes

echo "=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-"

### Change to the working directory of the qsub command.
###cd $PBS_O_WORKDIR

cd $HOME/an

### the full pathname as is done here.
mpd &
mpiexec -n 20 $HOME/an/mcmcRX
#mpiexec  $HOME/an/mcmcR

Thanks,
Abhishek.
