问题描述

当我尝试运行应用程序时(只是一个简单的hello_world.c不起作用)，每次都会收到此错误:

When I try to run an application (just a simple hello_world.c doesn't work) I receive this error every time:

mpiexec -ckpointlib blcr -ckpoint-prefix /tmp/ -ckpoint-interval 10 -machinefile /tmp/machinefile -n 1 ./app_name

[mpiexec@masterpi] main (./ui/mpich/mpiexec.c:331): process manager error waiting for completion

我只想做一个检查点，什么也不要做(稍后再重启).

I want just to make a checkpoint and nothing else (and restart later).

预先感谢

我已经尝试过MPICH2，没有机会.也许我在某个地方错了...

I have tried with MPICH2, no chance. Or maybe I'm wrong somewhere...

Test3-Code:

#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#include <mpi.h>

int main(int argc, char* argv[]) {

    int rank;
    int size;
    int i = 0;

    MPI_Init(&argc, &argv);
    MPI_Comm_rank(MPI_COMM_WORLD, &rank);
    MPI_Comm_size(MPI_COMM_WORLD, &size);

    MPI_Status status;

    if (rank == 0) {
        for(i; i <=100; i++){
            int j = 0;
            while(j < 100000000){
                j++;
            }
            printf("Count to: %i\n", i);
        }
    } else {
    }

    MPI_Finalize();
    return 0;

}

我只需要有一个成功的检查点并显示重启.如果有人有一个可行的例子(无关紧要的事，简单的"Hello World"工作将使我感到高兴！)我将非常高兴.

I just need to have one successful checkpoint and to show the restart.If someone has a working example (irrelevant what it makes, simple working "Hello World" would make me happy!) I would be very glad.

新年快乐！
