Japanese Supercomputer Fugaku becomes the world's fastest computer according to TOP500. The machine is installed at RIKEN Center for Computational Science (R-CCS) in Kobe and developed by Riken and Fujitsu. It's the first time a Japanese computer has topped the list. Normally US or China holds the record for making the best supercomputers. But this time Japan beats them all and secures the top position.
The new top system, Fugaku, turned in a High-Performance Linpack (HPL) result of 415.5 petaflops which is 2.8 times faster than the second placeholder IBM's Summit. Fugaku, is powered by Fujitsu's 48-core A64FX SoC, becoming the first number one system on the list to be powered by ARM processors.
The x86 continues to be the dominant processor architecture, being present in 481 of the 500 systems. Intel claims 469 of these, with AMD installed in 11 and Hygon in the remaining one. Arm processors are present in just four TOP500 systems, three of which employ the new Fujitsu A64FX processor, with the remaining one powered by Marvell's ThunderX2 processor.
Fugaku is set to go into full operation next fiscal year. So far it has been used on an experimental basis to research COVID-19, including diagnostics, simulating the spread of the SARS-CoV-2 virus, and the effectiveness of Japan's new contact tracing app.
