Hello, I'm a newbie on MPI, just playing around with the things. I've searched through the internet but couldn't find an appropriate code example for my problem.
I'm making comparisons, correlations on my cluster, and gaining the results like this: vector<ComparisonResult> results; In every node, they calculate and create the results array, in their local storage. And then I'd like to collect these vectors in my server node, rank (0). I had done this with MPI gather but just for double arrays, not with objects or vectors. I have some guess about MPI::Create_contiguous, or MPI::Create_vector functions, but all these ask for another associated MPI type, such as CHAR or INT or etc. And I don't know if I should use packing somehow... is there a way to collect these vectors in my server node with Gather function? or even with send & recv? Thanks a lot, -- Saygin
