title: When I run an MPI program, what is the meaning of this ? "mpirun noticed that the job aborted..."
body: <p>When I run my code I get the following message:</p>
  
  <blockquote>
    <p>mpirun noticed that the job aborted, but has no info as to the process that caused that situation</p>
  </blockquote>
  
  <p>My MPI code runs properly and gives expected output, but in the end I see this message. <strong>What does this mean and how do I get rid of it ?</strong>
  I am implementing an MPI reducer for this. I have a feeling that it has nothing to do with my code as such.</p>
