Using Charlie

Please do not run code directly on cfe, which has very limited resources. Jobs are submitted to compute nodes 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.


There is an active community of Charlie users on the Bigelow Slack workspace. Channels include: #comp-charlie and #comp-code. Please post questions there before emailing
