In the first two Warewulf articles, I finished the configuration of Warewulf so that I could run applications and do some basic administration on the cluster. Although there are a plethora of MPI

The first example is very simple: just a base OS along with the GCC compilers (GCC, G++, and GFortran). The HPCCM recipe is basically trivial

Programmers use a number of compilers, libraries, MPI libraries/tools, and other tools to write applications. For example, someone might code with OpenACC, targeting GPUs and Fortran, whereas another person
