PEZYはMIMDでコア数を増やし、かつ電力消費を抑えることを可能とした
他のシステムのコア数との違いから一目瞭然だ

This machine uses PEZY-SC2 accelerators, a second-generation 2048-core chip
that provides a peak performance of 4.096 teraflops in double-precision, as well
as conventional Intel Xeon processors, for a total of 19,860,000 cores. (An
earlier ZettaScaler machine with the PEZY-SC2 made the list at a lower level
on the June version). That gives it the highest number of cores used together-
also known as the highest level of concurrency - seen to date, surpassing the
TaihuLight, which has 10.6 million cores. The Gyoukou machine achieved a
Linpack sustained performance of 19.14 petaflops, but what's interesting is
that it uses 1.35 megawatts of power, compared to 2.27 megawatts for PizDaint,
17.8 megawatts for Tinahe-2, and 15.4 megawatts for Taihulight.

ベンチマークがLinpackであるなら、科学計算に必要な事はできる
今のところ目を通した批判は、Linpackさえ知らないか、コア数が持つインパクトを無視している
