New Python versions on Cheyenne, Casper

January 15, 2019

New installations of Python – versions 3.6.8 and 2.7.15 – are now available on both Cheyenne and Casper. These installations were compiled with GCC 7 and use Intel's MKL for accelerated Numpy performance. You can add the executables to your path using environment modules, and then load our library of packages using the NPL utility. See this page for more information on using CISL's Python libraries.

The default version of Python will be switched from 2.7.14 to 3.6.8 on both systems on Tuesday, January 22. This move to Python 3 follows the end of new feature development on the scientific Python stack for 2.7.
