Download




Extract and Install


  • Assume that the downloaded file is in your ~/Downloads directory
  • Just follow the directions in the INSTALL file, which are summarized below. The installation was done on *my* machine, and assumes the user is thiebaut. Change and plug-in your own user name.
  • open a Terminal window, and type the following commands in it:
cd
mkdir mpi
mkdir mpi/download
cd mpi/download
mv ../Downloads/openmpi-2.0.2.tar.bz2  .
tar -xzvf openmpi-2.0.2.tar.bz2
cd openmpi-2.0.2
./configure --prefix=/Users/thiebaut/mpi/    (replace thiebaut by your user name on your Mac)
 
  • The last command will take 10 minutes or so. When it is done, make all and install
make all install
  • This last command takes a while as well...


Update your path


  • edit the .bash_profile file in your main account directory.
  • locate the line that reads PATH=...
  • right below this line, add the new line
     PATH=$PATH:/Users/thiebaut/mpi/bin/       
  • and make sure your replace thiebaut by your account name!
  • source your .bash_profile so that the new path is learnt by your system
 cd
 source .bash_profile
  • You are done!


Testing


Create this file in the directory of your choice, and call it helloWorld.c:

/* C Example */
#include <stdio.h>
#include <mpi.h>


int main (argc, argv)
     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;
}


Compile and Run


mpicc -o hello helloWorld.c
mpirun -np 2 ./hello
Hello world from process 0 of 2
Hello world from process 1 of 2
  • If you see the two lines starting with "Hello world" on your screen, MPI was successfully installed on your system!
