That effort is inactive at this time. One reason is that you can achieve much of the same behavior by creating a separate thread for each blocking call that you want to be asynchronous, and most environments that support MPI dynamic processes also support threads.

Dear MPI-Forum,

I would like to ask about the status of the nonblocking process creation mechanism (aka Async-proc-mgmt) which I have found on the MPI Forum wiki pages. I am trying to implement dynamic resource allocation for my research work and I was thinking about nonblocking MPI_Comm_spawn counterpart. I have googled for "MPI_Icomm_spawn" and found the proposal details.

I am curious if any further development exist. Is there any reference implementation that might be usable? What does it mean in practice that this proposal is dormant, would it be included in any predictable future?

I would appreciate any hints or comments on the nonblocking process management with MPI.

Best Regards, Maciej Szpindler
