Sooner or later every cluster develops a plethora of tools and libraries for applications or for building applications. Often the applications or tools need different compilers or different MPI ... When people first start using clusters, they tend to stick with whatever compiler and MPI library came with the cluster when it was installed. As they become more comfortable with the cluster, using ... MPI, environment modules, compiler, resource manager ...
