The High Performance Conjugate Gradients (HPCG) Benchmark list was announced this week at SC15. This is the fourth 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 a year and a half ago, containing only 15 entries and the SC’14 list had 25. The current list contains more than 60 entries as HPCG continues to gain traction in the HPC community.
