【赛迪网讯】11月13日消息，据外电报道，IBM和英特尔本周一提高了在全球超级计算机500强排行榜中的名次。这个排行榜是计算机行业密切关注的一个进步标准。

这个排行榜是两年公布一次。IBM在美国劳伦斯利弗莫尔国家核实验室的蓝色基因/L超级计算机名列榜首。蓝色基因/L最近进行了升级，每秒钟的运算次数可达478万亿次。这个速度比普通的台式电脑速度快数万倍。

排名第二位的是IBM安装在德国研究中心的一台超级计算机，运算速度为每秒167万亿次。

排名第三的是由SGI基于Altix ICE8200模型新安装在新墨西哥Rio,N.M计算应用中心(NMCAC)的系统，运算速度为126.9万亿次。

排名第四的是第一次进入十强的印度，惠普为印度Tata Sons研究中心制造的超级计算机的运算速度为每秒117.9万亿次。

排名第五的是HP的集群平台3000 BL460c系统，安装在Swedish government agency，运算速度102.8万亿次。

BM占超级计算机500强排行榜的46%，惠普占33%。惠普在上一次公布的排行榜中排在领先的地位。

英特尔处理器占排行榜中超级计算机的64%。AMD处理器在500强排行榜中的比例从6个月前的21%下降到了16%。

500强中美国仍然是第一，占了284台，欧洲从127台上升到149台，亚洲从72太下降到了58台。其中日本从23台下降到20台，台湾从10台升到11台，中国大陆从13台下降到10台，印度从8台上升到9台。欧洲英国是第一，拥有48台（六个月前只有43台），第二的是德国，有31台（六个月前只有24台）。

Other trends of interest:

A total of 354 systems (72.2 percent) now use Intel processors. This is up from six months ago (289 systems, 57.8 percent) and represents the largest share for Intel chips in the TOP500 ever. The AMD Opteron family, which passed the IBM Power processors a year ago, remained the second most common processor family with 78 systems (15.6 percent), down from 105 systems (21 percent) six months ago. 61 systems (12.2 percent) use IBM Power processors, down from 85 systems (17 percent) six months ago.

A total of 406 systems are labeled as clusters, making this the most common architecture in the TOP500 with a stable share of 81.2 percent.

Gigabit Ethernet is still the most-used internal system interconnect technology (270 systems) due to its widespread use by industrial customers, followed by InfiniBand technology with 121 systems.

The U.S. is clearly the leading consumer of HPC systems with 284 of the 500 systems. The European share (149 systems - up from 127) is still rising and is again larger then the Asian share (58 - down from 72 systems).

Dominant countries in Asia are Japan with 20 systems (down from 23), Taiwan with 11 (up from 10), China with 10 systems (down from 13), and India with nine systems (up from eight).

In Europe, UK has established itself as the No. 1 with 48 systems (43 six months ago). Germany has to live with the No. 2 spot with 31 systems (24 six months ago).

The TOP500 list is compiled by Hans Meuer of the University of Mannheim, Germany; Erich Strohmaier and Horst Simon of NERSC/Lawrence Berkeley National Laboratory; and Jack Dongarra of the University of Tennessee, Knoxville.
