</div>what is the purpose of installing two MPI libraries? it only increases<br>
the chances of something going wrong. better pick one.<br>

</div>my guess would be you use the mpirun of one MPI library package with<br>
an executable compiled against the other, so it cannot forward you<br>
input, or you are making some even more fundamental error.<br>
<br>
the best thing to do would be to first compile and run some simple MPI<br>
test/demo programs so you get familiar with how to properly compile<br>
and run parallel programs. only after you are comfortable with it, you<br>
should move on to compiling/running pw.x<br>
