OpenMPI Raspberry Pi

Downloading OpenMPI and getting it up and running on a Raspberry Pi

This was done using CentOS on the RPi. You'll need some type of internet connection.

sudo yum install wget
wget "Link of what you want to download"

I used this link: https://www.open-mpi.org/nightly/master/ . Hover your mouse over the tarball at the top with the extension .gz.tar and in the bottom left hand corner you'll see a full link for this download. Put it in quotes in front of wget.

mv /home/tarballName /home/whatEverDirectoryYouWish      (It might not be necessary to move this file)
gunzip openmpi-master-X-Y.tar.gz
tar -xvf openmpi-master-X-Y.tar
