Linux still the su­per­power be­hind su­per­com­put­ers

Micro Mart - - Contetnts -

Su­per­com­put­ing has al­ways been an in­ter­est of mine, ever since learn­ing about the Cray2 from 1985 with its four liq­uid­cooled pro­ces­sors and 256 MWord mem­ory. It was like some­thing from sci­ence fic­tion, and I dreamed of one day be­ing able to be in com­mand of such an im­pres­sive ma­chine.

Although I never got to play around with a Cray Su­per­com­puter my job as a tech jour­nal­ist af­fords me some com­pen­sa­tion by be­ing one of the first to learn of new su­per­com­put­ing tech­nolo­gies. So I’m half-way there.

Re­cent news is that the cus­tom Linux-driven NVidia DGX SaturnV has been ranked as the world’s most ef­fi­cient su­per­com­puter – as well as be­ing the 28th fastest su­per­com­puter on the planet. The SaturnV is pow­ered by the firm's own Tesla P100 GPUs, of which it has 125, along­side 63,488GB of mem­ory and 60,512 In­tel Xeon E5-2698v4 pro­ces­sors. Im­pres­sively, this lit­tle lot is 2.3 times more en­ergy ef­fi­cient than the pre­vi­ous record holder, the Cam­phore 2.

The SaturnV is an ac­cel­er­ated AI su­per­com­puter, which is ca­pa­ble of per­ceiv­ing the world as we do; help­ing sci­en­tists and engi­neers find so­lu­tions to ev­ery­thing from global warm­ing to the best method for build­ing earthquake proof build­ing.

The AI por­tion is said to be the most ad­vanced ever de­vel­oped, and has the abil­ity to self-learn and de­sign deep learn­ing net­works for it­self, which isn’t scary in the slight­est.

Ja­pan's New Su­per­com­puter

China has his­tor­i­cally led the su­per­com­puter charts for quite a few years now. As of Novem­ber the coun­try holds both the first and sec­ond place fastest su­per­com­puter po­si­tions with the Tianhe-2 su­per­clus­ter, and the cur­rent leader, the Sun­way Tai­huLight – a sys­tem that boasts 1,310,720GB of mem­ory, 10,649,600 pro­cess­ing cores and runs the Linux-based Sun­way RaiseOS 2.0.5.

How­ever, de­spite China’s lead, Ja­pan is step­ping up to the plate by an­nounc­ing that it will soon be re­veal­ing a new $173 mil­lion su­per­com­puter that will be twice as pow­er­ful and fast as the cur­rent leader. At present, Ja­pan sits sixth and sev­enth in the charts but, ac­cord­ing to Satoshi Sekiguchi, the di­rec­tor-gen­eral at Ja­pan’s Na­tional In­sti­tute of Ad­vanced In­dus­trial Sci­ence and Tech­nol­ogy, this new sys­tem will in­cor­po­rate some new tech­nolo­gies that will give it the much needed boost to lead the charts for some time to come.

It is as­sumed that Fu­jitsu will be help­ing to build the sys­tem, along with soft­ware engi­neers who will be de­vel­op­ing a new Linux sys­tem to in­ter­pret the 130-petaflops the su­per­com­puter will gen­er­ate when it even­tu­ally goes live.

The big ques­tion of course is, will it run Cr­y­sis?
