Re: [OMPI users] Fwd: Can I just use non-blocking send/receive without calling MPI_Wait ever

Matthieu, I see your point, if I avoid calling mpi_test or wait, there is no data transfer at all. Sincerely Yours, Lei Shi - On Fri, Apr 3, 2015 at 5:17 PM, Matthieu Brucher wrote: > If you don't need to know if the data was transferred or not, then why

If you don't need to know if the data was transferred or not, then why do you transfer it in the first place? The schema seems kind of strange, as you don't have any clue that the data was actually transferred. Actually without Wait and Test, you can pretty much assume you don't transfer anything.

Hi Jeff, Thanks for your reminder. I don't need to make sure the data is correct or not. I know it sounds crazy at first time, but there are some numerical schemes designed for this situation. I just want to call MPI_ISend/MPI_IRecv without calling waiting or testing but can still run my program
