IBM doesn't just make some of the the most powerful supercomputers in the world; it makes some of the most energy-efficient supercomputers in the world, according to the latest Supercomputing Green 500 List announced by The Green500.org.
The report found that the top 20 most energy-efficient supercomputers in the world are 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. IBM also holds 39 of the top 50 positions on this list.
The most energy-efficient system in the world is an IBM supercomputer based on QS22 Blade servers at the Interdisciplinary Centre for Mathematical and Computational Modelling at the University of Warsaw. The system produces more than 536 Mflops (millions of floating point operations per second) per watt of energy.
By comparison, the first non-IBM entry on the list offers about half the performance, 240 Mflops per watt.
The recently announced world's fastest supercomputer, the IBM petaflop supercomputer at Los Alamos National Laboratories, is ranked ninth in energy efficiency, while the second most powerful supercomputer in the world manufactured by Cray is ranked 80th on the list, producing only 153 Mflops per watt.
"IBM has a rich history of innovation that has significantly increased microprocessor energy efficiency," said David Turek, vice president of deep computing at IBM, in a written statement. "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 datacenter costs and energy use."
The 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 list of worldwide supercomputers announced earlier this week by Top500.org.
