<p>Dear Aziz <br>
</p>
<p>is seems to be the typical behavior that usually occurs when
part of the code was compiled as serial --without __MPI defined in
make.inc, but finally linked with mpif90. Something could have
gone wrong when you executed the configure script. <br>
</p>
<p>I would <br>
</p>
<p>1) run configure again <br>
</p>
<p>2) check inside make.inc that -D__MPI is included in the DFLAGS
string</p>
<p>3) recompile again</p>
<p>I hope that it works <br>
</p>
<p>regards - Pietro <br>

<div dir="ltr">Dear Quantum espresso team, I am Aziz Fall from the
University of Michigan Ann Arbor, I am getting an issue
specifically when I call mpirun with more than 1 core. When I
run it with just 1 core I have no issues, but when I specify
more than 1 core on my 32 core machine I get the following error
