Abstract
Luna and Typhoon are two Top500 supercomputers running production scientific workloads at LANL. Interestingly, users have reported substantially better-than-expected performance gains from Luna, the newer of the two. In this paper we present our methodology for investigating the source of this improvement and determining what architectural changes for future supercomputers would most benefit LANL applications.
