Fugaku and its PrimeHPC FX1000 derivatives maintained the ~2.5-3% of peak that the PrimeHPC FX100 had in HPCG.

While not quite as efficient as K, which dominated the HPCG benchmark until Summit and Sierra were released, 2.6% in an unoptimized early stage is extremely good.

That’s going to be the key to Fugaku’s domination of HPCG and outperforming systems that beat it in HPL FLOPS.

Summit and Sierra are 1.5% of peak, and Taihulight is 0.4% for comparison to other large systems. Nothing can really beat a system like Fugaku because everything is a spared no expense, bespoke design for HPC.

It will be interesting to see if Fugaku can stay at the top of the HPCG and Graph500 lists when systems with 10x the HPL FLOPS come out the way that K did.
