Question

我有一些简单的代码可以用GNU编译器很好地编译。然后我切换到PGI编译器。但是该程序将失败。我正在使用具有Xeon E5 CPU 16处理器和两张GPU卡，一张泰坦和一张1080的台式机进行编译。

我在以下简单的hello世界中进行了测试，

npm run eject

错误如下

#include <mpi.h>
#include <iostream>

using namespace std;

int main(int argc, char **argv){
        int procid, numprocs;
        MPI_Init(&argc, &argv);
        MPI_Comm_rank(MPI_COMM_WORLD, &procid);
        MPI_Comm_size(MPI_COMM_WORLD, &numprocs);

        cout << "hello world"<< endl;

        MPI_Finalize();
        return 0;
}

以下是mpic ++的结果

Sorry!  You were supposed to get help about:
    orte_init:startup:internal-failure
But I couldn't open the help file:

我在设置相同的笔记本电脑上尝试了相同的操作。编译良好，没有问题。我开始怀疑是多GPU引起了问题。由于每个GPU都有不同的PGI目标，因此我尝试了-ta = tesla：cc70和-ta = tesla：cc60。都不行。

我不知道如何调试它，如果需要更多信息，可以添加它。
