L\u2011CSC<\/span> Emer\u00adges as the Most Ener\u00adgy-Effi\u00adci\u00adent Super\u00adcom\u00adpu\u00adter in the World<\/em><\/p>\n

New Orleans, LA<\/span>, USA<\/span>; Novem\u00adber 20, 2014 \u2013<\/strong> A new super\u00adcom\u00adpu\u00adter, L\u2011CSC<\/span> from the GSI<\/span> Helm\u00adholtz Cen\u00adter, emer\u00adged as the most ener\u00adgy-effi\u00adci\u00adent (or gree\u00adnest) super\u00adcom\u00adpu\u00adter in the world, accor\u00adding to the 16th edi\u00adti\u00adon of the twice-year\u00adly Green500 list of the world\u2019s most ener\u00adgy-effi\u00adci\u00adent super\u00adcom\u00adpu\u00adters. The L\u2011CSC<\/span> clus\u00adter was the first and only super\u00adcom\u00adpu\u00adter on the list to sur\u00adpass 5 gigaflops\/watt (bil\u00adli\u00adons of ope\u00adra\u00adti\u00adons per second per watt). It was powered by Intel Ivy Bridge CPUs and a FDR<\/span> Infi\u00adni\u00adband net\u00adwork and acce\u00adle\u00adra\u00adted by AMD<\/span> Fire\u00adPro\u2122 S9150<\/span> GPUs.<\/p>\n

In fact, the top three slots of the Green500 were powered by three dif\u00adfe\u00adrent acce\u00adle\u00adra\u00adtors with num\u00adber one, L\u2011CSC<\/span>, being powered by AMD<\/span> Fire\u00adPro\u2122 S9150<\/span> GPUs; num\u00adber two, Sui\u00adren, powered by PEZY-SC<\/span> many-core acce\u00adle\u00adra\u00adtors; and num\u00adber three, TSUBAME-KFC<\/span>, powered by NVIDIA<\/span> K20x GPUs. Bey\u00adond the\u00adse top three, the next 20 super\u00adcom\u00adpu\u00adters were also accelerator-based.<\/p>\n

L\u2011CSC<\/span> achie\u00adved the first posi\u00adti\u00adon on the Novem\u00adber 2014 Green500 List with an impres\u00adsi\u00adve 5.27 giga\u00adflops per watt. This sys\u00adtem used Intel Ivy Bridge CPUs, AMD<\/span> Fire\u00adPro GPUs, and ener\u00adgy-effi\u00adci\u00adent soft\u00adware design to achie\u00adve this feat. Sui\u00adren, a super\u00adcom\u00adpu\u00adter from the High Ener\u00adgy Acce\u00adle\u00adra\u00adtor Rese\u00adarch Organization\/KEK<\/span> in Japan, occu\u00adp\u00adied the second spot at 4.95 giga\u00adflops per watt. Like L\u2011CSC<\/span>, it used Intel Ivy Bridge CPUs, but cou\u00adpled them with many-core acce\u00adle\u00adra\u00adtors from PEZY-SC<\/span>. Final\u00adly, TSUBAME-KFC<\/span>, which was the most ener\u00adgy-effi\u00adci\u00adent super\u00adcom\u00adpu\u00adter over the pre\u00advious two edi\u00adti\u00adons of the Green500, came in third in this edi\u00adti\u00adon of the Green500. TSUBAME-KFC<\/span> was the first super\u00adcom\u00adpu\u00adter to have bro\u00adken the 4 gigaflops\/watt bar\u00adri\u00ader. Like the other two acce\u00adle\u00adra\u00adtor-based machi\u00adnes, it used Intel Ivy Bridge CPUs, but cou\u00adpled with NVIDIA<\/span> K20x GPUs.<\/p>\n

Other high\u00adlights from this Green500 List include the following:<\/strong><\/p>\n

This marks the first time that a super\u00adcom\u00adpu\u00adter (L\u2011CSC<\/span>) using AMD<\/span> GPUs has held the top spot.
\nThe Sui\u00adren super\u00adcom\u00adpu\u00adter is the first sys\u00adtem desi\u00adgned with cus\u00adtom acce\u00adle\u00adra\u00adtors to enter the top five sin\u00adce Novem\u00adber of 2010, when the GRAPE-DR<\/span> super\u00adcom\u00adpu\u00adter achie\u00adved the same feat.
\nThe PEZY-SC<\/span> many-core acce\u00adle\u00adra\u00adtors in the Sui\u00adren super\u00adcom\u00adpu\u00adter use ARM<\/span> con\u00adtrol\u00adled cores. This repres\u00adents the first time that an ARM-based chip has appeared so pro\u00admin\u00adent\u00adly on the list.<\/p>\n

Assum\u00ading that L\u2011CSC<\/span>\u2019s ener\u00adgy effi\u00adci\u00aden\u00adcy could be sca\u00adled line\u00adar\u00adly to an exa\u00adflop super\u00adcom\u00adpu\u00adting sys\u00adtem, one that can per\u00adform one tril\u00adli\u00adon floa\u00adting-point ope\u00adra\u00adti\u00adons per second, such a sys\u00adtem would con\u00adsu\u00adme on the order of 190 mega\u00adwatts (MW<\/span>). \u201cAlt\u00adhough this 190-mega\u00adwatt power enve\u00adlo\u00adpe is still far from DARPA<\/span>\u2019s opti\u00admi\u00adstic tar\u00adget of a 67-mega\u00adwatt power enve\u00adlo\u00adpe, it is appro\u00adxi\u00adm\u00adate\u00adly 16 times bet\u00adter than the initi\u00adal pro\u00adjec\u00adtion of a near\u00adly 3000-mega\u00adwatt power enve\u00adlo\u00adpe from 2007 when the first offi\u00adci\u00adal Green500 list was laun\u00adched,\u201d says Wu Feng of the Green500.<\/p>\n

About the Green500:<\/strong><\/span><\/p>\n

The Green500 has pro\u00advi\u00added a ran\u00adking of the most ener\u00adgy-effi\u00adci\u00adent super\u00adcom\u00adpu\u00adters in the world sin\u00adce Novem\u00adber 2007. For deca\u00addes, the noti\u00adon of super\u00adcom\u00adpu\u00adter \u201cper\u00adfor\u00admance\u201d has been syn\u00adony\u00admous with \u201cspeed.\u201d This par\u00adti\u00adcu\u00adlar focus has led to the emer\u00adgence of super\u00adcom\u00adpu\u00adters that con\u00adsu\u00adme egre\u00adgious amounts of elec\u00adtri\u00adcal power and pro\u00addu\u00adce so much heat that extra\u00adva\u00adgant coo\u00adling faci\u00adli\u00adties must be con\u00ads\u00adtruc\u00adted to ensu\u00adre pro\u00adper ope\u00adra\u00adti\u00adon. In addi\u00adti\u00adon, when the\u00adre is an empha\u00adsis on speed as the ulti\u00adma\u00adte metric, it often comes at the expen\u00adse of other per\u00adfor\u00admance metrics, such as ener\u00adgy effi\u00adci\u00aden\u00adcy, relia\u00adbi\u00adli\u00adty, avai\u00adla\u00adbi\u00adli\u00adty, and usa\u00adbi\u00adli\u00adty. As a result, the\u00adre has been an extra\u00ador\u00addi\u00adna\u00adry increase in the total cost of owner\u00adship (TCO<\/span>) of a super\u00adcom\u00adpu\u00adter. Con\u00adse\u00adquent\u00adly, the Green500 seeks to rai\u00adse the awa\u00adre\u00adness in ener\u00adgy effi\u00adci\u00aden\u00adcy of super\u00adcom\u00adpu\u00adting and to dri\u00adve it as a first-order design cons\u00adtraint on par with speed.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
