Code is not run directly on cfe, which has very limited resources. Rather jobs are submitted to Charlie's nodes (e.g. c1, c2, and c3) using the PBS Pro job scheduler. Only basic programs and utilities are installed on the nodes themselves. To use software packages that are not installed locally (or a different version than what is installed locally) you will use environment modules.
