ps. If you are interested in parallelism... there is Julia. https://docs.julialang.org/en/v1/manual/parallel-computing/index.html
I would also advise setting up just one server and install the latest CentOS. You can start with some tutorials on MPI - which is the current standard for parallelism. you can then install OpenHPC on the same server as OpenHPC is an 'overlay' then start building the cluster.
