Subject: Re: [OMPI users] OpenMPI multithreaded performance

Thank's for your answer and sorry for misunderstanding.

My question is about performance of this implementation regarding the use
of multithreading capabilities.

Of course MPI+OpenMP is a choice but (for what I understand) you should
obtain a lot of performances also using MPI multithreading capabilities
(for example in the communication part of your code) and without using
OpenMP.

So, the question is if this is true with the current implementation of
OpenMPI

Thank's again

Piero
