Green500 Names IBM the Provider of the World's Most Energy Efficient Supercomputers

The Green500 list is published by Green500.org. It evaluates the top 500 supercomputers in the world from the TOP500 list and ranks them in the order of energy efficiency.

Green500.org. has just published its latest Supercomputing 'Green500 List' and according to it, IBM's (News - Alert) supercomputers happen to be the world's most energy efficient in the world.
 
Currently supercomputers are used in variety of fields including astronomy, climate prediction and pharmaceutical research. The list considered supercomputers from many countries including China, Germany and the United States, where the supercomputers are being used for a variety of applications in the above mentioned fields. The Green500 list pointed out 17 of the top 20 most energy efficient supercomputers in the world are built on IBM high-performance computing technology. IBM also holds 65 of the top 100 positions on this list.
 
IBM technology offers some unique advantages to its clients that its computers fail to provide.
 
Energy efficiency, including performance per watt for the most computationally demanding workloads, has long been a core design principle in developing IBM systems. Apart from being the most energy efficient, IBM systems are also the most affordable. Energy efficient supercomputers allow IBM clients to realize critical cost savings by lowering power consumption and reducing expenses associated with cooling.
 
In fact, with IBM systems, client have been able to save on energy in million.
According to IBM, clients seeking to achieve petascale performance who deploy systems based on IBM Blue Gene/P -- which is over 40 percent more energy efficient than other supercomputers on the market -- can realize savings on energy in excess of $1 million dollars a year.
 
For the second time, three QPACE systems occupied the top slot in the list of world's most energy efficient systems.  QPACE systems are based on the IBM PowerXCell 8i processor.
 
Germany's Julich Supercomputing Centre, University of Regensburg and University of Wuppertalare are all tied for the top spot on the Green500 list. The systems each produce more than 773 Mflops (millions of floating point operations per second) per watt of energy.
 
IBM offers the broadest range of generally applicable supercomputers represented on the Green500 List including Blue Gene, Power servers, System x iDataPlex, BladeCenter and hybrid clusters.
 
Mississippi State University (MSU) operates the most energy efficient x86-only cluster on the list, which ranks 9th overall on the Green500. MSU's iDataPlex cluster supports a broad set of multi-discipline research projects from aerospace and fluid dynamics to hurricane modeling in the U.S. Gulf.
 
"Our IBM iDataPlex cluster will allow us to accelerate the University's important research -- including collaborations with government agencies and corporate entities -- while minimizing our power and cooling costs and taking up less space. This fits with MSU's environmentally conscious mission and ensures we are making the most of the University's resources," said Trey Breckenridge, high performance computing resources and operations administrator for MSU's HPC2.
