High performance computing is a necessity for scientific research and increasingly so; however initial steps are also being made in vocational engineering at RMIT. Applying the andragogical principles in the education sector with free and open source content encourages educational connectivism which improves learning and relevance.

Julia is a high-level, high-performance dynamic language for technical computing. With a "just in time" compiler, it is very fast, especially compared to languages like MATLAB, Octave, R etc. However it is relatively new and a cluster installation and package deployment has a few quirks.
Download the source from github. By default you will be building the latest unstable version of Julia from the git checkout. However, we want to run 0.4.0 (or rather, 0.4rc4) which is the last stable release.
# cd /usr/local/src/JULIA

Many Android devices come with storage configurations that are surprising to end-users. A product that is advertised as having 32 gigabytes of memory may in fact turn out to have much less available in terms of installing applications.

Mr. Bayes is a program for Bayesian inference and model choice across a wide range of phylogenetic and evolutionary models.
Download, extract. Note that the developers have produced a tarbomb which will require a separate directory created before download. This has been raised as a bug.
Note that more recent versions of MrBayes make much better use of autoconfiguration tools.

JAGS is Just Another Gibbs Sampler. It is a program for analysis of Bayesian hierarchical models using Markov Chain Monte Carlo (MCMC) simulation not wholly unlike BUGS.
tar xvf JAGS-3.4.0.tar.gz
mv JAGS-3.4.0 jags-3.4.0
The config script takes the following form
install=$(basename $(pwd) | sed 's%-%/%')
