Some of the highest-ranked supercomputers on TOP500 list were also top performers on the High-Performance Conjugate Gradient (HPCG) benchmark. In fact, the top two Linpack performers, Summit and Sierra, captured the first two positions on the HPCG benchmark. Summit achieved 2.93 HPCG-petaflops and Sierra, 1.80 HPCG-petaflops.
They are followed by the previous HPCG leader, Fujitsu’s K computer, which delivered 0.60 HPCG-petaflops; it is ranked 18thin the TOP500. Trinity grabbed the number four HPCG position, with 0.55 HPCG-petaflops, followed by the ABCI system at 0.51 HPCG-petaflops. Those two systems are ranked 6th and 7th, respectively in the TOP500. Piz Daint, Sunway Taihulight, Nurion, Oakforest-PACS, and Cori round out the top ten.
