%0 Generic %D 2013 %T Toward a New Metric for Ranking High Performance Computing Systems %A Michael A. Heroux %A Jack Dongarra %X The High Performance Linpack (HPL), or Top 500, benchmark is the most widely recognized and discussed metric for ranking high performance computing systems. However, HPL is increasingly unreliable as a true measure of system performance for a growing collection of important science and engineering applications. In this paper we describe a new high performance conjugate gradient (HPCG) benchmark. HPCG is composed of computations and data access patterns more commonly found in applications. Using HPCG we strive for a better correlation to real scientific application performance and expect to drive computer system design and implementation in directions that will better impact performance improvement. %B SAND2013 - 4744 %8 2013-06 %G eng %U http://www.netlib.org/utk/people/JackDongarra/PAPERS/HPCG-Benchmark-utk.pdf
