I need to transfer data from multiple sources to one destination.You've already gotten a number of suggestions, but I thought I'd add my $0.02 to help you (hopefully) sort them out. I agree with Terry that you should read up on MPI_ANY_SOURCE. With this, you can listen for any source process and use functions like MPI_Recv or MPI_Irecv. I further agree that you could consider functions like MPI_Probe or MPI_Iprobe. Win's examples don't seem to apply since they implement gathers (one input from each process) and you explicitly said that no such regularity can be assumed. Biagio's suggestion might be helpful, but also sounds like it might be overkill. |
