In fact Japan's Fugaku comes in fourth in Linpack but first in the HPCG benchmark, beating out Frontier. If you take a look at HPCG performance, the scores are substantially lower than you'd expect to see from Linpack. Some of the early testing of HPCG is designed to more closely reflect real world performance in a wide variety of HPC workloads. 'Satoshi Matsuoka has been talking about 'all these benchmarks are important can we come up with some type of composite Green500 number of FLOPS per watt by somehow combining the numbers we get from the different benchmarks'.' 'Mike Heroux and Jack Dongarra in particular have broached this subject about looking at the Green500 using HPCG,' he explained. Over the past 18-24 months there has been a growing movement to broaden the scope of the Green500 to alternative workloads, Wu-chun Feng explained during a presentation at SC23. That, however, may not be the case for much longer. But while we've found new ways to benchmark supercomputers in terms of performance, the Green500 remains tied to Linpack.
