Subject: Re: [OMPI users] How to enable progress threads in 1.6?
From: Filippo Donida (filippo.donida_at_[hidden])

My idea is to have a thread to be launched just after the MPI_Isend call with a fake MPI_Test function call, just to make the sending operation progressing. Do you think this may work?

Regards,

Filippo.

Not sure I understand the question - the progress thread option just enables async progress to be made. All MPI functions will progress whenever you call into the MPI library today - they just won't progress while you are, for example, running a non-MPI computation in your program.
