The world’s first supercomputer petaflopny retires




The world’s first supercomputer petaflopny retires

Five years ago, IBM for the Department of Energy has created a supercomputer simulation of the collapse of the U.S. nuclear arsenal. At that time, Roadrunner was considered the performance of the computer in the world. In June 2008, a supercomputer with a capacity of more than one quadrillion calculations per second (petaflop) took first place in the Top 500 list. The last time the title of the strongest computer Roadrunner confirmed in June 2009. Today it is deprecated and should be written off.

As the resource Arstechnica, supercomputer, installed at the Los Alamos National Laboratory in New Mexico, will be examined first, and then dismantled. Although Roadrunner is still considered one of the most powerful computers in the world (22 seats), by today’s standards, it is not enough energoneeffektivnym as too much power.

“For five years, Roadrunner, which became part of the Advanced Simulation and Computing (ASC) of the National Nuclear Security Administration U.S. has done a lot of research,”

– The representative of the Centre for Defence Nuclear Research in Los Alamos.

Roadrunner worth more than $ 120 million uses 122,400 processors on 296 server racks with a mix of InfiniBand. All it takes is an area of ​​approximately 560 square meters. The supercomputer has a hybrid scheme for constructing IBM PowerXCell 8i and AMD Opteron dual-core. AMD processors are responsible for performing basic tasks and solutions Cell incur large amounts of computation, acting as an accelerator.


In November 2009, Roadrunner gave the title of world’s fastest computer at a computer Jaguar hybrid architecture AMD Opteron and Cray, who also enlisted in the U.S. Department of Energy. Today Jaguar 1.76 petaflops performance is part of a powerful cluster called Titan. Supercomputer Cray Titan took first place in the top in November last year with a score of 17.6 petaflops.

Currently, scientists are working on computer systems whose performance is 1000 petaflops. However, the issue of energy efficiency is still open.

Roadrunner supercomputer can still be used for scientific purposes, but energy efficiency is significantly inferior to its competitors. According to the November ranking of supercomputers, to achieve the performance 1.042 petaflop Roadrunner should consume 2345 kWh of electricity – 22 on the list. For this purpose supercomputer number 21 requires 1177 kW, and the number 23 (1.035 petaflops performance) – total 493 kW of electricity.

“To increase the availability and performance of the next generation of supercomputers need by saving. Future computing systems will require the introduction of new technologies for processing and storing large amounts of data, ”

– Speak at the Los Alamos National Laboratory.

After shutting down the system, scientists will investigate Roadrunner another month. Then, the first petaflopny supercomputer will be fully dismantled and sent into retirement.

The hour is short, when supercomputers equip artificial intelligence . Over such sverhmashinoy already working scientists IBM.
