Цитата: HPL reported 26.25 Gflops on its WR00R2R4 operation. Microwulf also exceeded 26 Gflops on other operations, but 26.25 Gflops was our maximum. This is significant computational power. For example, according to the top500 list, a 1996 Cray T3D-256 provided just 25.3 Gflops of measured performance.
