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

Dear OpenMPI team
hiw much performances we should expect using MPI multithread capability
(MPI_init_thread in multiple format).
It seems that no performance exist using some simple test like multiple mpi
channel activated, overlapping comm and computation and so on
Thank's in advance
