标题: 美国德州大学与SUN合作制造400TFLOPS超级计算机，采用AMD四核处理器
Computers are getting bigger in Texas, too.

The University of Texas is getting one of the world's most powerful supercomputers, having learned Thursday that it had won a $59 million grant from the National Science Foundation for the big machine.

The new computer, to be built by Sun Microsystems Inc. using 13,000 microprocessors made by Advanced Micro Devices Inc., will be more powerful than any supercomputer currently in operation, UT says.

It will have a peak computing power of more than 400 trillion operations per second, which makes it more than 40 percent faster than the current supercomputing speed champ, Blue Gene/L, developed by IBM Corp. for the Lawrence Livermore National Laboratory in California.

The processor chips to be used in the machine's final configuration will be AMD's quad-core Opteron processors, which will be in production in mid-2007.

UT is teaming with Cornell University in New York and Arizona State University on the project, which is expected to be completed next fall. The federal funds pay for both the computer itself and operating expenses for four years.

It will be by far the largest computer that is attached to the TeraGrid, a National Science Foundation-sponsored network of high-performance computers.

Other, still more powerful machines are being developed for the nation's federal laboratories, but the Texas machine easily vaults UT to the very front ranks of academic supercomputing.

"In many ways, this is the national championship of high-performance computing, and we won it," said Jay Boisseau, director of the Texas Advanced Computing Center, which will run the machine. "We are incredibly excited."

The computing center at the J.J. Pickle Research Campus in North Austin has grown in size and stature since Boisseau became director five years ago.

Its current speed champion, the Dell Lonestar Cluster, begins operating next week.

The computing center employs 60 computer researchers and other technical workers, about five times as many people as it had in 2001. It will add another 15 workers over the next year to help run the new computer, Boisseau said.

The new machine is expected to be used by hundreds of academic and government researchers nationwide, who will apply to a national review committee for approval to use the new machine. Five percent of its capacity will be set aside for other Texas universities, and another 5 percent will be allotted to an industrial partners program.

The machine is expected to handle complex computing problems confronting researchers in dozens of scientific and technical disciplines.

Klaus Schulten, head of the Theoretical and Computational Biophysics Group at the University of Illinois, said the machine will help researchers better understand how cells work, how viruses infect human cells and how proteins fight obesity within cells.

现在计划的几台最大的超级计算机似乎都看中K8L了嘛。

呵呵，amd在高端渐入佳境。

x86 继续统治全球 100 年，我看在我们有生之年看不到新指令的崛起了

必须要从软件上脱离对X86的依赖
linux可以很舒服的下源码来装软件
而JAVA更是平台无关性

现在这个情况，与其说是X86在统治，倒不如说是微软在统治。

高性能计算M$还是小弟弟。
x86杀入高端完全是其他的原因。

高端？
高端X86根本算不上统治吧。

TOP500里看起来名额不少，但是主要还是在中等性能的超级计算机中运用。

确实K8要搞几台大的了，但那也不是X86的原因，只是K8的内存性能确实优越外加多路链接模式也是比较好的。

X86的强势更多的是成本因素。正因为在PC上分担了大部分成本，X86显得非常有吸引力。而且PC市场上残酷的竞争使得X86处理器性能突飞猛进，和有些不思进取的精简指令处理器的缓慢发展形成鲜明对照。从这点上说，未来X86在服务器市场上占据统治地位是很快的事。

嗯，X86有个人电脑市场作为支撑，研发投入和成本都能分摊，这是很重要的原因

:) 恩，是觉得有些精简指令处理器不思进取，尤其是SUN的。

不过，占统治地位倒不会，X86还是有其固然的缺点的。

如果单纯论理论FLOPS，这台东西的性能成本是Roadrunner的6.8倍。

opteron的架构不错,关键是与桌面平台通用,

x86的也就跑一般的东西
拿我们的计算软件一跑就知道
ia64 的安藤2 1.6g可以消灭所有op和xeon了

不是一个档次的
