OpenMPI NFS Raspberry Pi

Download the tarball into the shared folder (How to do that here: https://github.com/dylanchristopherson/aws-pmix-scale-testing/wiki/OpenMPI-Raspberry-Pi). Then:

cd /opt/nfsshare
mkdir build         //I gave the same permissions to build as nfsshare had. Check using ls -al

./configure --prefix=/opt/nfsshare/build --enable-static --enable-orterun-prefix-by-default  

The --prefix stores the files in the build folder. The path can be what ever you'd like. The default path is /usr/local/ I believe. --enable-static allows for static building. And --enable-orterun-prefix-by-default is supposed to set the path so frutilla could execute the mpirun/orterun commands.

To check if the path is set correctly:

which mpirun          //Or which orterun

If a line comes up saying something along the lines of not found:

cd /opt/nfsshare/build/bin           //mpirun and orterun folders should be in here
PATH=$PATH:/opt/nfsshare/build/bin
export PATH

Now try

which mpirun       //Or which orterun

And a path to those commands should pop up
