Hi Arthur,<br>
<br>
The performance issue you are mentioning is very likely to be
specific to your code. Unless you identify a performance problem
in MPICH, we are not able to help you here. You may look for
assistance in a forum specialized in your specific application
domain, or in a general-purpose coding forum such as
stackoverflow.<br>
<br>
Best,<br>
Antonio<br>
