Re: [OMPI users] MPI_SCAN

Hi jeffy, Thanks for your reply. I am not understanding how MPI_Reduce would be useful. Say I have 3 processes and each process has array [1,2,3,4] When each process calculates the prefix sum using cuda each process will have array as [1,3,6,10] so if I use MPI_Reduce to gather results it retu
