OpenMPI runtime error : Hello World

Question

当我执行 make 命令时，我能够成功编译我的代码。但是，当我运行代码为：

mpirun -np 4 test

产生的错误是：

-------------------------------------------------------
Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[63067,1],2]
  Exit code:    1
--------------------------------------------------------------------------

我没有安装多个 mpi，所以我预计不会出现问题。

我的 Hello World OpenMPI 程序一直有问题。我的主文件是：

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

using namespace std;

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


    MPI_Init(NULL, NULL);

    int size, rank;

    MPI_Comm_size(MPI_COMM_WORLD, &size);
    MPI_Comm_rank(MPI_COMM_WORLD, &rank);

    cout << "The number of spawned processes are " << size << "And this is the process " << rank;

    MPI_Finalize();


    return 0;

}

我的 makefile 是：

# Compiler 
CXX = mpic++

# Compiler flags
CFLAGS = -Wall -lm

# Header and Library Paths
INCLUDE = -I/usr/local/include -I/usr/local/lib -I..
LIBRARY_INCLUDE = -L/usr/local/lib
LIBRARIES = -l mpi

# the build target executable
TARGET = test

all: $(TARGET)

$(TARGET): main.cpp
    $(CXX) $(CFLAGS) -o $(TARGET) main.cpp $(INCLUDE) $(LIBRARY_INCLUDE) $(LIBRARIES)


clean:
    rm $(TARGET)

mpic++ --version 的输出是：

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

mpirun --version 是：

mpirun (Open MPI) 2.1.1

是什么导致了这个问题？

此问题现已解决。原来我必须执行

mpirun -np 4 ./test
