win10 安装Mpi	lindexi	2018-2-13 17:23:3 +0800	2018-2-13 17:23:3 +0800	Win10

首先我们需要安装Bash

$ sudo apt-get install libcr-dev mpich2 mpich2-doc

写hello.c

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

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

  MPI_Init (&argc, &argv);      /* starts MPI */
  MPI_Comm_rank (MPI_COMM_WORLD, &rank);        /* get current process id */
  MPI_Comm_size (MPI_COMM_WORLD, &size);        /* get number of processes */
  printf( "Hello world from process %d of %d\n", rank, size );
  MPI_Finalize();
  return 0;
}

使用mpicc ，[[INVALID],INVALID] ORTE_ERROR_LOG: A system-required executable either could not be found or was not executable by this user in file ess_singleton_module.c at line 231

$ mpicc.mpich2 hello.c -o h

$ mpiexec.mpich -np <num> ./h

I use mpiexec.mpich run the code.mpicc.mpich2 hello.c -o h mpiexec.mpich -np <num> ./h

可以安装mpi，从http://download.csdn.net/detail/lindexi_gd/9714817 下载，使用

tar zvf  openmpi-1.6.5.tar.gz  
cd openmpi-1.6.5
./config
sudo make & make install
