The computer hardware giant IBM has once again topped the Green500 list which includes a range of energy efficient supercomputers all around the globe. It has been reported that the company holds 18 of the top 20 positions on the list, successfully towering over others.
David Turek, vice president, deep computing, IBM commented that the era of supercomputers being focused upon raw performance was coming to an end. He also added that clients should be able to run the supercomputers in any environment and not only in places that have cheap power.
He said that the Green500 list had proven once again that IBM is intently focused on this issue and is well positioned to usher in performance breakthroughs along with efficiency gains.
The company claims that the most energy efficient trio of supercomputers made by it is at Julich supercomputing center in Germany which produces more than 732 Mflops per watt of energy. The forth and fifth place was taken by BladeCenter clusters, using the PowerXCell 81.
The National Astronomical Observatory of Japan's GRAPE-DR cluster came seventh while it was followed on the list by National SuperComputer Center in Tianjin/NUDT's TH-1 cluster which runs on Intel Xeon CPUs. Position 9 to 22 was dominated by IBM Blue Gene/P systems.
IBM's supercomputers it seems have managed to carve a pretty interesting niche in the world of HPC. Even then, the amount of power consumed by these machines is particularly high and need significant investment either to power those or to keep them cool. The future might be to use distributed clusters like SETI instead.
