title: Slurm does not allocate the resources and keeps waiting
body: <p>I'm trying to use our cluster but I have issues. I tried allocating some resources with:</p>
  <pre><code>salloc -N 1 --ntasks-per-node=5 bash
  </code></pre>
  <p>but It keeps wainting on:</p>
  <blockquote>
  <p>salloc: Pending job allocation ...</p>
  <p>salloc: job ... queued and waiting for resources</p>
  </blockquote>
  <p>or when I try:</p>
  <pre><code>srun -N1 -l echo test
  </code></pre>
  <p>it lingers at waiting queue!</p>
  <p>Am I making a mistake or there is something wrong with our cluster?</p>
