Green 500 List Puts IBM Supercomputers at the Top

ARMONK, N.Y., July 24 -- When it comes to supercomputing energy efficiency, IBM cannot be beaten -- that's according to the findings of the latest Supercomputing 'Green 500 List' announced by The Green500.org.

No fewer than the top 15 positions in the ranking of energy efficiency are held by supercomputers built on IBM high performance computing technology.

The list includes supercomputers from across the globe being used for a variety of applications such as astronomy, climate prediction and pharmaceutical research.

Ranking the recently announced world's fastest Los Alamos National Laboratories petaflop supercomputer at number three for energy performance -- the list is topped by IBM's own Boeblingen Lab supercomputer which is used for development of IBM blade computing systems.

"Energy efficiency has become just as important as simple raw performance for the modern supercomputer. As applications for supercomputers increase, so does the attention on this aspect of their use," said Dave Turek, VP Deep Computing.

"Leveraging our $6 billion annual R&D investment, IBM has a rich history of innovation that has significantly increased microprocessor energy efficiency. We have also driven advances that include our Cool Blue technology portfolio and added to our Project Big Green solutions that are designed to simultaneously reduce data center costs and energy use," he added.

The third annual Green 500 list is published by The Green500.org. It provides a ranking of the most energy-efficient supercomputers in the world and serves as a complementary view to the TOP500 announced in Dresden last month.

In the ranking:

IBM holds all top ten places with a number of IBM BladeCenter QS22 and LS21 Clusters and Blue Gene/P Solutions.
Out of the first 40 ranked systems, 39 are IBM-based.
Out of the top 100 systems, 76 systems are IBM-based.
The top three supercomputers -- all IBM -- surpass the 400 MFLOPS/watt milestone for the first time -- with the leading system delivering almost half a GFLOP per watt.

In addition to the energy efficient technology solutions, IBM is focused on numerous areas related to energy and the environment, including sustainable supply chains, solar technology, carbon management consulting, advanced water management, intelligent utility networks and intelligent transportation systems.

NASA Looks to Move Science Apps Into the Cloud

It seems only natural that the US space agency would be casting its eyes toward the clouds. Sure enough, NASA is now looking to cloud computing to optimize the operation of the agency's IT infrastructure for some of its science codes. Like many commercial businesses and government organizations, NASA is being asked to do more computing with fewer datacenter resources.

Thoughts, Observations, Beliefs & Opinions About the NSF Supercomputer Centers

There is no such thing as an NSF (Supercomputer) Center and there never has been. There should be. What there are, in the words of Ed Hayes, then comptroller of NSF, are "NSF ASSISTED Supercomputer Centers." This is a double edged sword.

Appro Assists LLNL with Cluster Designed for Extreme Scale Visualization

Jan 11 | | LLNL is home to some of the fastest computers in the world. In 2012, LLNL expects to have the Sequoia supercomputing cluster operational with a projected performance of over 20 PFLOP/s. These systems will focus on strengthening the foundations of predictive simulation through running large suites of complex simulations and then comparing model predictions with experimental data. To visualize this project’s large amount of data, LLNL requested an Appro Supercomputing Cluster specifically designed to support interactive data analysis.
