HPCG Benchmark: a New Metric for Ranking High Performance Computing Systems∗
نویسندگان
چکیده
We describe a new high performance conjugate gradient (HPCG) benchmark. HPCG is composed of computations and data access patterns commonly found in scientific applications. HPCG strives for a better correlation to existing codes from the computational science domain and be representative of their performance. HPCG ismeant to help drive the computer system design and implementation in directions that will better impact future performance improvement.

Toward a New Metric for Ranking High Performance Computing Systems 1 June 10 , 2013
. The High Performance Linpack (HPL), or Top 500, benchmark [1] 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) ben...

متن کاملPerformance Modeling of the HPCG Benchmark
The TOP 500 list is the most widely regarded ranking of modern supercomputers, based on Gflop/s measured for High Performance LINPACK (HPL). Ranking the most powerful supercomputers is important: Hardware producers hone their products towards maximum benchmark performance, while nations fund huge installations, aiming at a place on the pedestal. However, the relevance of HPL for realworld appli...
متن کاملAn Approach to the Highest Efficiency of the HPCG Benchmark on the SX-ACE Supercomputer
This paper reports how we have achieved the world’s highest efficiency on the HPCG benchmark by fully exploiting the high potential of the SX-ACE supercomputer. To achieve efficient vector calculations and memory accesses, several optimization techniques such as ELL sparse matrix data packing, the hyperplane method for eliminating data dependencies, selective caching for the on-chip memory, and...
