Lynx was a Cray XT5m supercomputer.

The system name was chosen because “a lynx is a small jaguar” and Jaguar was, at the time, a similar (but much bigger) Cray XT system at the National Center for Computational Science. For more information on Jaguar, see https://www.ornl.gov/news/oak-ridge-jaguar-supercomputer-worlds-fastest

Lynx was acquired by NCAR as a test and evaluation platform, rather than a full production supercomputer like its counterpart, Bluefire.  CISL determined that the investment in a test Cray XT5m was of strategic importance, and while the system was used by CISL system administrators and computational scientists, many NCAR users also used Lynx for production computing to offload work from Bluefire.  Lynx was installed in the NCAR Mesa Laboratory's computer facility and used for three and a half years.  Despite being a test and evaluation platform, over its lifetime Lynx's average utilization was 49.3%.  It was decommissioned October 1, 2013, after the opening of the NCAR-Wyoming Supercomputing Center (NWSC) and CISL's deployment of Yellowstone, the inaugural supercomputer at the NWSC, in production.
