Fugaku is a Japanese
supercomputer that now holds the top position in the biannual Top500 supercomputer speed ranking. It is co-developed by Riken and Fujitsu and uses the
Fujitsu 48-core A64FX system-on-chip. It’s actually making history by becoming
the first-ever ARM processor to top this list.
Do you know that Fugaku
was spotted in the Top 500 HPL result of 415.5 petaflops, 2.8 times as fast as
IBM’s Summit, which is its nearest competitor? Cool, right?
Also, Fugaku is coming
out on top in other lists including Graph 500, HPL-AI, HPCG. This is another
historical achievement as no other computer has come close to attaining top
positions in all four categories at once.
Usually, you get to see
supercomputers categories led by American and Chinese companies but this is the
first time in nine years that a Japanese brand has taken control. In total,
there are 226 Chinese supercomputers on the list and 114 American
supercomputers. Interestingly, Japan only has 30 supercomputers running in the
Fugaku will become
fully operational by the next fiscal year. As of now, it is only being used for experimental research on COVID-19.
