According to Green500.org, IBM supercomputers are the most energy-efficient in the world.
In fact, the latest Supercomputing 'Green500 List' announced by Green500.org shows that a prototype of IBM's next-generation Blue Gene/Q supercomputer is No. 1 on the list.
The Green500 provides rankings of the most energy-efficient supercomputers in the world. The organization raises awareness about power consumption, promotes alternative total cost of ownership performance metrics, and works to ensure that supercomputers only simulate climate change and not create it. The Green500 list has three releases per year: November, February and June
The latest list shows that six of the top 10 most energy-efficient supercomputers in the world are built on IBM high-performance computing technology, IBM said. The list includes supercomputers from China to Germany and the United States that are used for a variety of applications such as astronomy, climate prediction and life sciences. IBM also holds over half the top 100 positions on this list, IBM said.
Energy efficiency, including performance per watt for the most computationally demanding workloads, has long been a core design principle in developing IBM systems, according to IBM officials. Energy-efficient supercomputers can allow IBM clients to realize critical cost savings by lowering power consumption and reducing expenses associated with cooling. For example, for every $1 spent on electricity with the largest petascale system on the Green500 list, clients would spend less than 40 cents on a system based on IBM Blue Gene/Q and would be 2.5 times more energy-efficient, IBM said in a press release.
IBM Blue Gene/Q is scheduled to be deployed in 2012 by two of the U.S. Department of Energy's national laboratories, Lawrence Livermore National Laboratory and Argonne National Laboratory, both of which collaborated closely with IBM on the design of Blue Gene, influencing many aspects of the system's software and hardware, IBM said.
