June 19, 2017 — The High Performance Conjugate Gradients (HPCG) Benchmark list will be announced at ISC’17. This is the seventh list produced for the emerging benchmark designed to complement the traditional High Performance LINPACK (HPL) benchmark used as the official metric for ranking the TOP500 systems. The first HPCG list was announced at ISC’14 three years ago, containing only 15 entries.
Release twice a year, the number of entries has steadily increased. The current list contains 110 entries as HPCG continues to gain traction in the HPC community. The 7th list contains entries from many of the TOP500’s highest ranked systems, but continues to provide a significantly different ordering. Of particular note is the ranking of the Sunway TaihuLight, which remains at the top of the HPL list for the third time, but has dropped from third (ISC16) to fourth (SC16) to fifth on the current HPCG list. For HPL, the Sunway system was about 3 times faster than the second place system (Tianhe-2). For HPCG, it is about 2 times slower than the fastest machine.
The 7th HPCG Performance List will be presented at ISC’17 on Wednesday, at 11:30 in the Konstrast Room at ISC on June 21, 2017.
Highlights from the 7th HPCG list
• HPCG list of supercomputing sites now features 110 entries, majority of them from the very top of the TOP500 list.
• The Riken/Fujitsu K Computer is in first place, a spot it claimed at SC16.
• The upgraded Piz Daint system from CSCS is third on the list
• The Sunway TaihuLight system is ranked 5th for HPCG, despite being ranked 1st for TOP500.
• The HPCG list has been integrated into the TOP500 list for the first time.

About the HPCG Benchmark Project
The High Performance Conjugate Gradients (HPCG) Benchmark Project started over two years ago as an effort to probe important characteristics of a computer system, highlighting and rewarding investment in system features, such as high performance interconnects, memory systems, and fine grain cooperative threading, that are important to a broad set of applications. HPCG has emerged as a complementary benchmark to the traditional High Performance LINPACK (HPL) benchmark used to rank the TOP500 systems. The pair of numbers provided by HPCG and HPL act as bookends on the performance spectrum of a given system.
