Running Open MPI on macOS

I am, generally, against all these automation stuff (brew, etc.) at macOS. I prefer to install everything from sources (as long as it is possible).

So, here are few steps to get Open MPI up and running at macOS. Please make sure to download source package from: https://www.open-mpi.org/software/ompi/v2.0/downloads/openmpi-2.0.2.tar.gz.

Now, it’s time for Hello world! code.

And, eventually, we can compile and run it

That’s all.
