Re: [OMPI users] MPI_Reduce problem

Hi Jelena, int* ttt = (int*)malloc(2 * sizeof(int)); ttt[0] = myworldrank + 1; ttt[1] = myworldrank * 2; if(myworldrank == 0) MPI_Reduce(MPI_IN_PLACE, ttt, 2, MPI_INT, MPI_SUM, 0, MPI_COMM_WORLD); //sum all logdetphi from different nodes else MPI_Reduce(ttt, NULL, 2, MPI_INT, MPI_SUM,
