EXECUTIVE SUMMARY
"Oak Ridge National Laboratory's Leadership Computing Facility (OLCF)
continues to deliver the most powerful resources in the U.S. for
open science. At 2.33 petaflops peak performance, the Cray XT Jaguar
delivered more than 1.4 billion core hours in calendar year (CY) 2011
to researchers around the world ..."
....
"Effective operations of the OLCF play a key role in the scientific
missions and accomplishments of its users. This Operational Assessment
Report (OAR) will delineate the policies, procedures, and innovations
implemented by the OLCF to continue delivering a petaflop-scale resource
for cutting-edge research. This report covers CY 2011 that unless
otherwise specified, denotes January 1, 2011 through December 31, 2011."
