Oak Ridge National Laboratory unveils "Kracken" - a new supercomputer that would run alongside "Jaguar," the second fastest supercomputer in the world capable of a peak capability of 1.6 petaflops:

http://www.tmcnet.com/usubmit/2008/12/26/3878860.htm

Quote:
The new system -- nicknamed Kraken, after a mythical sea monster -- should be ready for research in early 2009, according to lab officials.

.....

In its initial phase, Kraken will have a peak capability of more than 600 teraflops (600 trillion calculations per second). It will be upgraded about a year from now to achieve a peak of about 1 petaflops (or 1,000 trillion calculations per second).

.....

In an interview earlier this year, Zacharia talked about plans for having two petascale computers available at the lab. Jaguar should be the world's best computer for open scientific users, and Kraken should be the top machine dedicated to academic users, he said.

The two Cray supercomputers could be hooked together and operated as one if there are special projects that require their combined computing power, Zacharia said.

The real innovation in the supercomputing field that everyone should be talking about:

http://computerworld.com/action/article.do?command=viewArticleBasic&articleId=9120741

Quote:
Nvidia today unveiled a workstation it calls the Tesla Personal Supercomputer at the Supercomputing 08 show here. The Tesla sports 960 cores, delivers almost 4 teraflops of performance and costs less than $9,995. It achieves that speed and price by using four graphics processing units (GPU), each of which has 240 cores.

"This really is the supercomputer on your desk," Dell Inc. CEO Michael Dell told attendees at the conference, which drew more than 10,000 science and commercial high-performance computing users, along with a slew of vendors hoping that the high-performance computing (HPC) market will be a bright spot in otherwise difficult tech economy. The attendance was a new record for this annual conference.

.....

Dell has produced a workstation in its Precision line that uses the Nvidia GPU chip, and a number of other vendors are producing systems based on Nvidia's parallel computing architecture.

This is type of system is designed to support applications that require a high degree of parallelization, such as visualizations, seismic studies, biomedical research and product design, among others. Nvidia released a software development kit about a year ago so independent software developers could build applications to run on the new system.

Latest "Top 500 list" just released:

http://www.top500.org/lists/2008/11/press-release

Some highlights:

Quote:
The entry level to the list moved up to the 12.64 Tflop/s mark on the Linpack benchmark, compared to 9.0 Tflop/s six months ago.

The last system on the current list would have been listed at position 267 in the previous TOP500 just six months ago.

Total combined performance of all 500 systems has grown to 16.95 Pflop/s, compared to 11.7 Pflop/s six months ago and 6.97 Pflop/s one year ago.

The U.S. is clearly the leading consumer of HPC systems with 291 of the 500 systems (up from 257). The European share (151 systems – down from 184) is settling down after having risen for some time, but is still substantially larger then the Asian share (unchanged at 47 systems).

Dominant countries in Asia are Japan with 18 systems (down from 22), China with 16 systems (up from 12), India with 8 systems (up from 6).
In Europe, UK remains the No. 1 with 45 systems (53 six months ago). Germany fell steeply but is still in the No. 2 spot with 24 systems (46 six months ago).

Cray XT "Jaguar" supercomputer and Roadrunner in a race to secure the top position in the new "Top 500" list to be released next week. Note that the new number 2 will have ten times the computing power of the former number 2 just 18 months ago, as can be seen in the first post of this thread:

We now have a new number one on our hands - in the form of Cray XT "Jaguar" supercomputer at the Department of Energy's Oak Ridge National Laboratory:

http://www.informationweek.com/news/hardware/supercomputers/showArticle.jhtml?articleID=212001621

Quote:
The beefed-up Jaguar has a peak performance of 1.64 petaflops, compared with the Roadrunner's 1.026 petaflops. The Roadrunner is used for nuclear security and scientific research at the Los Alamos National Laboratory.

...

The upgraded Jaguar already has been used by scientists to complete a superconductivity calculation that required a sustained performance of more than 1.3 petaflops. Superconductivity is a phenomenon characterized by exactly zero electrical resistance. The phenomenon occurs in certain materials generally at very low temperatures.

...

"The new petaflops machine will make it possible to address some of the most challenging scientific problems in areas such as climate modeling, renewable energy, materials science, fusion, and combustion," said Michael Strayer, associate director of the DOE Office of Science for Advanced Scientific Computing Research.

The faster Jaguar is expected to be a boon for U.S. industry by making it possible to perform "virtual prototyping" of complex systems and products. Such prototyping reduces development costs and shortens the time required to market new technologies, the DOE said.

6th fastest supercomputer in the most unlikely of places: Saudi Arabia.
-----------------------------------------------------------------------------------
Saudi supercomputer lures researchers
Mon Oct 20, 2008 11:32am EDT

By Asma Alsharif

JEDDAH, Saudi Arabia (Reuters) - A new science and technology university in Saudi Arabia will house one of the world's largest supercomputers and it is helping lure top researchers to the conservative desert state.

The King Abdullah University of Science and Technology (KAUST) is due to open next year on the Red Sea coast near Jeddah, the most liberal city in a country where religious conservatives have extensive control over society.

Inside the campus, male and female students will be able to mingle freely, contrary to strict gender segregation enforced in most of the country. The university is part of a series of reforms by King Abdullah aiming to open the country up.

"The supercomputer is the cornerstone of this knowledge-based economy that we are seeking," said Majid Al-Ghaslan, in charge of the acquisition, design and development of the "Shaheen" supercomputer.

Named after the peregrine falcon, which reaches speeds of up to 340 kilometers per hour, Shaheen is expected to reach 222 teraflops, a measure equaling a trillion floating point operations per second, Ghaslan said. This will make it sixth most powerful computer in the world.

Shaheen will be able to simulate the Red Sea environment and model oil fields in three dimensions.

Although Saudi Arabia has immense financial resources as the world's biggest oil exporter, the parameters of school and university education are governed by religious strictures and many subjects are even off-limits for women to study.

The new university will offer research in biosciences and bioengineering, material sciences and engineering, applied mathematics and computational sciences.

With a $10 billion donation to its endowment from King Abdullah, it is able to lure experts from around the globe with the promise of almost unlimited funding for research work.

"KAUST is a remarkable addition to the world's resources in high-end computing," said David Keyes, Chair of the Mathematical and Computer Sciences and Engineering Division, who is moving from Columbia University in the United States.

"The machine that is being purchased here is one of the main attractions to me," he said.

The supercomputer will be used by KAUST and its partners including Cornell University, the University of Oxford, Stanford University, and Texas A&M University.

Stanford's Folding@Home project's current performance about to surpass four petaflops. Note that its performance just surpassed three petaflops a month ago!

http://fah-web.stanford.edu/cgi-bin/main.py?qtype=osstats

At this rate, we should see this approach/surpass five petaflops by the end of October.

The biggest "computer" of them all is taking a new direction:

In a recent Nvidia presentation they mentioned that if all Nvidia GPUs 8 series plus were put to work on folding@home they would add 7000 pentaflops of computing power to folding@home.

If you add this to programmable ATI GPUs, Xbox360s and the ps3 you would have a seriously fast exaflop supercomputer. Cool

Add all the worlds computing power in and you would be in the zettaflop range or close to it I would think.
