Software for Cheyenne users

The software packages listed below and others are or can be made available on the Cheyenne system or for use on the Casper data analysis and visualization nodes. For a list of software modules and versions that are on these systems today, see:

Contact CISL if you have suggestions for additional software to include or if a package that you need is not available.

Don’t run "sudo" on CISL systems
Use of the sudo command on Cheyenne and other systems that CISL manages is restricted to authorized users and CISL staff members. The command fails and raises a security alert to the system administrators when unauthorized users try to run it – for example, when attempting to install software packages system-wide or to act on other users’ files. CISL logs such failed attempts and contacts users to offer assistance. If you need help with tasks that you think require sudo privileges, or if you aren’t sure, it is best to contact CISL before running sudo yourself.
