IBM Supermarket was the world's best IBM Roadrunner retired

For the first time in history 1Petaflops (PFLOPS)IBM's attention as a system that has reached the processing capacity of IBMRoadrunnerHowever, on March 31, 2013 all functions stopped, and the curtain was closed in its lifetime.

End of the road for Roadrunner

RoadrunnerIn 2008TOP 500It was the first supercomputer to surpass 1PFLOPS by recording 1.026PFLOPS greatly away from Blue Gene / L (478.2TFLOPS) in 2nd place, but in the November 2009 ranking it became second only to Jaguar and in 2012 It ranked 22nd in ranking.


Many of the top 25 superior computers in existence are petaflops and Roadrunner is still boasting a remarkable speed, but in terms of efficiencyExaScaleSupercomputer is winning. Roadrunner will release 2345Kilowatt (KW)1042 PFLOPS was recorded and ranked 22nd, but the 21st ranked supercomputer had only 1035PFLOPS at 1177KW and only 493KW at 23rd place. According to the Los Alamos laboratory, "Supercomputers need to be made more economical by increasing energy efficiency" in the future, and also from the necessity of responding to the rapid increase in the amount of data generated by supercomputers , Researchers are turning their attention to ExaScale supercomputer, which is considered to be 1000 times faster than Petaflops, and that he will do many research and development in the future.


Roadrunner stopped on March 31. Although it is only five years since becoming the world's largest in 2008, researchers are planning to perform memory compression technology of operation system and experiment of data routing over a month before disassembly, development of future supercomputer It seems to be useful for. "These experiments did not work while Roadrunner was moving, Roadrunner is our learning material, even if we die," said Gary Grider of the Los Alamos laboratory.
