Hi Arthur,

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.

Best,
Antonio
