title: error in using "qsub" when allocating nodes
body: <p>my script (13-4.sh) is :</p>
  
  <pre><code>#!/bin/sh
  #PBS -N sample
  #PBS -l nodes=4:ppn=64
  #PBS -q batch
  #PBS -o $HOME/qpms9-2/out/14-4.out
  #PBS -e $HOME/qpms9-2/error/14-4.out
  #PBS -l walltime=100:00:00
  mpirun $HOME/qpms9-2/run_mpi $HOME/qpms9-2/14-4 -l 14 -d 4
  </code></pre>
  
  <p>when i write this command : qsub 13-4.sh<br>
  The answer is as follows:
  qsub: Job exceeds queue resource limits MSG=cannot satisfy queue max nodes requirement</p>
  
  <p>my cluster has 10 nodes (64 core per node)</p>
