The Fuji\u00adtsu-built sys\u00adtem is equip\u00adped with Intel Xeon Gold pro\u00adces\u00adsors and NVIDIA<\/span> Tes\u00adla V100<\/span> GPUs, achie\u00adving an HPL<\/span> result of 19.9 petaflops.<\/p>\n

SuperMUC-NG is in the num\u00adber nine posi\u00adti\u00adon with 19.5 peta\u00adflops. It\u2019s instal\u00adled at the Leib\u00adniz-Rechen\u00adzen\u00adtrum (Leib\u00adniz Super\u00adcom\u00adpu\u00adting Cent\u00adre) in Gar\u00adching, near Munich. The Leno\u00advo-built machi\u00adne is powered by Intel Pla\u00adti\u00adnum Xeon processors.<\/p>\n

The Las\u00adsen super\u00adcom\u00adpu\u00adter is ran\u00adked num\u00adber 10, deli\u00adve\u00adring 18.2 peta\u00adflops. Instal\u00adled at Law\u00adrence Liver\u00admo\u00adre Natio\u00adnal Labo\u00adra\u00adto\u00adry, Las\u00adsen is the unclas\u00adsi\u00adfied coun\u00adter\u00adpart to the clas\u00adsi\u00adfied Sier\u00adra sys\u00adtem and shares the same IBM<\/span> Power9\/NVIDIA<\/span> V100<\/span> GPU<\/span> architecture.<\/p>\n

The most powerful new super\u00adcom\u00adpu\u00adter on the list is AiMOS, which shows up at posi\u00adti\u00adon 25, tur\u00adning in an HPL<\/span> result of 8.0 peta\u00adflops. The IBM-built sys\u00adtem is instal\u00adled at the Rens\u00adse\u00adlaer Poly\u00adtech\u00adnic Insti\u00adtu\u00adte Cen\u00adter for Com\u00adpu\u00adta\u00adtio\u00adnal Inno\u00adva\u00adtions (CCI<\/span>), and like Sum\u00admit, Sier\u00adra, and Las\u00adsen, it is equip\u00adped with Power9 CPUs and NVIDIA<\/span> V100<\/span> GPUs. <\/p>\n

Geo\u00adgra\u00adphi\u00adcal breakdown<\/strong><\/p>\n

The num\u00adber of TOP500<\/span> instal\u00adla\u00adti\u00adons in Chi\u00adna con\u00adti\u00adnues to rise and now sits at 227, up from 219 six months ago. Mean\u00adwhile, the share of US-based sys\u00adtem remains near its all-time low at 118. Howe\u00adver, sys\u00adtems in the US<\/span> are on avera\u00adge signi\u00adfi\u00adcant\u00adly lar\u00adger, which trans\u00adla\u00adted to a 37.8 per\u00adcent share of the list\u2019s aggre\u00adga\u00adte per\u00adfor\u00admance. Chi\u00adna is clo\u00adse behind with a 31.9 per\u00adcent per\u00adfor\u00admance share. Howe\u00adver, com\u00adpared to six months ago, this per\u00adfor\u00admance gap has shrunk. The June 2019 list had the US<\/span> with a 38.4 per\u00adcent of the list\u2019s aggre\u00adga\u00adte per\u00adfor\u00admance and Chi\u00adna with 29.9 percent.<\/p>\n

Japan remains in third place in the num\u00adber of TOP500<\/span> sys\u00adtems, with 29, fol\u00adlo\u00adwed by France with 18, Ger\u00adma\u00adny with 16, the Net\u00adher\u00adlands with 15, Ire\u00adland with 14, and the United King\u00addom with 11. All other count\u00adries were in the sin\u00adgle digits.<\/p>\n

Ven\u00addor shares<\/strong><\/p>\n

 As a reflec\u00adtion of China\u2019s domi\u00adnan\u00adce in sheer num\u00adbers, the top three sys\u00adtem ven\u00addors with regard to the num\u00adber of instal\u00adla\u00adti\u00adons are Leno\u00advo, (174), Sugon (71), and Inspur (65). Cray is num\u00adber four, with 36 sys\u00adtems, and HPE<\/span> is num\u00adber five, with 35. Note that Cray is now part of HPE<\/span>, so taken tog\u00ade\u00adther they would effec\u00adtively tie Sugon with 71 systems.<\/p>\n

At the chip level, Intel con\u00adti\u00adnues its domi\u00adnan\u00adce. Its pro\u00adces\u00adsors are pre\u00adsent in 470 of the 500 sys\u00adtems, split bet\u00adween mul\u00adti\u00adple gene\u00adra\u00adti\u00adons of Xeon and Xeon Phi hard\u00adware. IBM<\/span> is second with 14 sys\u00adtems \u2013 10 with Power CPUs and four with Blue Gene\/PowerPC CPUs. AMD<\/span> claims just three sys\u00adtems on the cur\u00adrent list.<\/p>\n

The\u00adre are now two Arm-based super\u00adcom\u00adpu\u00adters on the list: the Astra sys\u00adtem deploy\u00aded at San\u00addia Natio\u00adnal Labo\u00adra\u00adto\u00adries, which is equip\u00adped with Marvell\u2019s ThunderX2 pro\u00adces\u00adsors, and Fujitsu\u2019s A64FX<\/span> pro\u00adto\u00adty\u00adpe sys\u00adtem, a pre\u00adcur\u00adsor to the Fug\u00ada\u00adku (Post\u2011K) exas\u00adca\u00adle sys\u00adtem desti\u00adned for RIKEN<\/span> in 2021. The Fuji\u00adtsu machi\u00adne is new to the list and occu\u00adp\u00adies posi\u00adti\u00adon 159, with an HPL<\/span> per\u00adfor\u00admance of 2.0 petaflops.<\/p>\n

NVIDIA<\/span> is the domi\u00adnant ven\u00addor for acce\u00adle\u00adra\u00adtors. Its GPUs are pre\u00adsent in 136 of the 145 acce\u00adle\u00adra\u00adted sys\u00adtems. On the pre\u00advious list six months ago, the\u00adre were 134 acce\u00adle\u00adra\u00adted systems.<\/p>\n

Inter\u00adcon\u00adnect breakdown<\/strong><\/p>\n

Ether\u00adnet is used in 52 per\u00adcent (258) of the TOP500<\/span> sys\u00adtems, while Infi\u00adni\u00adBand is the net\u00adwork-of-choice in 28 per\u00adcent (140) of sys\u00adtems. Howe\u00adver, from a per\u00adfor\u00admance per\u00adspec\u00adti\u00adve, tho\u00adse posi\u00adti\u00adons are rever\u00adsed, with Infi\u00adni\u00adBand-based machi\u00adnes repre\u00adsen\u00adting 40 per\u00adcent of the TOP500<\/span>\u2019s aggre\u00adga\u00adte per\u00adfor\u00admance and Ether\u00adnet-based machi\u00adnes with 29 per\u00adcent. Cus\u00adtom inter\u00adcon\u00adnects, with just 46 instal\u00adla\u00adti\u00adons, cla\u00adim 22 per\u00adcent of the list\u2019s instal\u00adled performance.<\/p>\n
