China dom­i­nates new list of world’s top su­per­com­put­ers

China Daily (Hong Kong) - - BUSINESS -

WASHINGTON—Once again, China tops a new list of the world’s fastest su­per­com­put­ers, not only tak­ing the first two places, but also pulling ahead of the United States in the sheer num­ber of sys­tems be­ing used.

Ac­cord­ing to a bian­nual rank­ing of the world’s 500 fastest su­per­com­put­ers, called the Top500 pub­lished on Mon­day, China’s Sun­way Tai­huLight main­tains the lead as the No 1 sys­tem for the fourth time, with a per­for­mance of 93.01 petaflops.

China’s Tianhe-2, or Milky Way-2, re­mains the No 2 sys­tem at 33.86 petaflops. In­tel chip­based Tianhe-2 had topped the list for three years un­til it was dis­placed in November 2015 by Tai­huLight, which was built by en­tirely us­ing pro­ces­sors de­signed and made in China.

No 3 is Switzer­land’s Piz Daint, which is also the most pow­er­ful su­per­com­puter in Europe. A new sys­tem in Ja­pan, called Gy­oukou, is No 4, push­ing Ti­tan, the top US sys­tem, to No 5.

For the sec­ond time in a row there is no sys­tem from the US among the top 3, Top500 said.

And that’s not all. The 50th edi­tion of the Top500 rank­ing also shows that China has over­taken the US in the to­tal num­ber of ranked sys­tems by a mar­gin of 202 to 144.

“It is the largest num­ber of su­per­com­put­ers China has ever claimed on the Top500 rank­ing, with the US pres­ence shrink­ing to its low­est level since the list’s in­cep­tion 25 years ago,” Top500 said.

“China now clearly shows a sub­stan­tially larger num­ber of in­stal­la­tions than the United States.”

China has also over­taken the US in ag­gre­gate per­for­mance as well. The Asian coun­try now claims 35.3 per­cent of the Top500 places, with the US in sec­ond place with 29.8 per­cent.

When it comes to com­pa­nies mak­ing these sys­tems, US-based Hewlett-Packard En­ter­prise has the lead in the num­ber of in­stalled su­per­com­put­ers at 123, which rep­re­sents nearly a quar­ter of all Top500 sys­tems.

China’s Len­ovo fol­lowed HPE with 81 sys­tems, down from 88 sys­tems on the June list, and an­other Chi­nese com­pany called In­spur jumped to the third po­si­tion with 56 sys­tems, up from the sixth place and 20 sys­tems only six month ago.

Liu Jun, In­spur’s high per­for­mance com­put­ing gen­eral man­ager, said China and its re­search in­sti­tutes and com­pa­nies have in­vested a lot in sup­port­ing HPC re­search, de­vel­op­ment and in­no­va­tion.
