that's all for the notice from output error? I guess the output error<br>has more detail.<br><br>Have you ever tried to run some typical example of parallel running on<br>your computer before running QE?<br>Maybe the problem come from kind of package mpi that you are using.!!!<br>

<div>Dear Linh and Carlo,</div>
<div>The problem is solved. The mpi was the one automatically configured by configure script for parallel version.</div>
<div>After compilation, i cannot run it with openmpi (the errors come out). But it work perfectly fine with mpich on my quad core in parallel mode with all 4 cores.</div>
<div> </div>
<div>Thanks for the help.</div>
