Mpi &引用；ORTED“U CMD”处理器：卡在无限循环中-正在中止”；

在进行最终归约（我的程序中一组矩阵的求和）时，如下所示

struct Tomo {

    typedef Eigen::Matrix<int, HISTOGRAM_BOXES, HISTOGRAM_BOXES, Eigen::RowMajor> HistoMtx;

    HistoMtx exp_val;
    HistoMtx u;

我不明白这意味着什么，也不明白什么会触发它。这似乎是OpenMPI内部的问题。

可能是底层网络的问题或其他需要管理员注意的问题。例如：

struct buffer_set {
    Tomo * X;
    Tomo * Y;
    Tomo * Z;
} buffers[2];

if(rank == 0){
    /* MASTER NODE */
    for(int source=1; source<size; source++){
        printf("Reducing from %i\n", source);

        for(int i=0;i<env_count;i++){
            MPI_Recv(buffers[1].X[i].exp_val.data(), buffers[1].X[i].exp_val.size(), MPI_INT, source, 0, MPI_COMM_WORLD, &status);
            MPI_Recv(buffers[1].Y[i].exp_val.data(), buffers[1].Y[i].exp_val.size(), MPI_INT, source, 0, MPI_COMM_WORLD, &status);
            MPI_Recv(buffers[1].Z[i].exp_val.data(), buffers[1].Z[i].exp_val.size(), MPI_INT, source, 0, MPI_COMM_WORLD, &status);

            MPI_Recv(buffers[1].X[i].u.data(), buffers[1].X[i].u.size(), MPI_INT, source, 0, MPI_COMM_WORLD, &status);
            MPI_Recv(buffers[1].Y[i].u.data(), buffers[1].Y[i].u.size(), MPI_INT, source, 0, MPI_COMM_WORLD, &status);
            MPI_Recv(buffers[1].Z[i].u.data(), buffers[1].Z[i].u.size(), MPI_INT, source, 0, MPI_COMM_WORLD, &status);

        }

        merge_buffers(0, 1);
    }

    WriteH5File("h5file.h5", 0);

}else{
    /* SLAVE NODES */
    for(int i=0;i<env_count;i++){
        MPI_Send(buffers[0].X[i].exp_val.data(), buffers[0].X[i].exp_val.size(), MPI_INT, 0, 0, MPI_COMM_WORLD);
        MPI_Send(buffers[0].Y[i].exp_val.data(), buffers[0].Y[i].exp_val.size(), MPI_INT, 0, 0, MPI_COMM_WORLD);
        MPI_Send(buffers[0].Z[i].exp_val.data(), buffers[0].Z[i].exp_val.size(), MPI_INT, 0, 0, MPI_COMM_WORLD);

        MPI_Send(buffers[0].X[i].u.data(), buffers[0].X[i].u.size(), MPI_INT, 0, 0, MPI_COMM_WORLD);
        MPI_Send(buffers[0].Y[i].u.data(), buffers[0].Y[i].u.size(), MPI_INT, 0, 0, MPI_COMM_WORLD);
        MPI_Send(buffers[0].Z[i].u.data(), buffers[0].Z[i].u.size(), MPI_INT, 0, 0, MPI_COMM_WORLD);
    }
}
