Abstract

The Oak Ridge Leadership Computing Facility (OLCF) housed at the Oak Ridge National Laboratory recently acquired a 200-cabinet Cray XK6. The computer will primarily provide capability computing cycles to the U.S. Department of Energy (DOE) Office of Science INCITE program. The OLCF has a tradition of installing very large computer systems requiring unique methods in order to achieve production status in the most expeditious and efficient manner. This paper will explore some of the methods that have been used over the years at OLCF to eliminate both early-life hardware failures and ongoing failures giving users a more stable machine for production.
