Japanese supercomputer wins greenest supercomputer award

According to an updated world data by global green supercomputer ranking organization Green500, the world’s most energy efficient supercomputer currently resides in the Land of the Rising Sun.


Supercomputers may have a specific focus on processing power or operation capacity, but with our current awareness of the huge economic advantages of energy efficiency, it’s always better and more beneficial for any tech to hold the best green card possible.

Last week, Green500 has just presented yet again the top ranking for the greenest supercomputers in the world, where the winner was none other than TSUBAME-KFC, a heterogeneous supercomputer system developed and owned by the Tokyo Institute of Technology (TITech).

The supercomputer was reported to be capable of delivering an operation capacity of 4.53 gigaFLOPS per single watt of power. This achievement was made possible through the use of an oil-based fluid cooling system, where all of the supercomputer’s primary components are constantly submerged within large “baths” of special oil. For comparison, the Chinese Tianhe-2, which is currently the fastest and most powerful supercomputer operating at 33.86 petaFLOPS, only has a rated efficiency of 1.9 gigaFLOPS per watt.

TSUBAME 3.0, which would be the technical successor to the experimental TSUBAME-KFC, would also focus on the same energy-efficient system its predecessor had, and would be scheduled for completion at around 2015. As for the other rankings, the second place was taken by Cambridge University’s Wilkes supercomputer (at 3.6 gigaFLOPS per watt), and the third place by Tsukuba University’s HA-PACS supercomputer (at 3.5 gigaFLOPS per watt).
