IBM Sequoia

from Wikipedia, the free encyclopedia

Sequoia is a Blue Gene / Q supercomputer from IBM . It is located in the Lawrence Livermore National Laboratory .

With a computing power of 16.3 petaflops , it was considered the most powerful supercomputer in the world from June 2012. In November 2012 he was just overtaken by the Titan (17.6 PFLOPS). In June 2013 both were overtaken by Tianhe-2 with 33.86  P FLOPS .

application

The IBM Sequoia was developed for the National Nuclear Security Administration to research new energy sources and to simulate and improve the lifespan of nuclear weapons systems to eliminate underground testing .

Technical specifications

With the announcement of the current TOP500 list on June 18, 2012 at the International Supercomputer Conference ISC12 in Hamburg , the IBM Sequoia rose from 17th place to first place in the LINPACK benchmark list of the most powerful computers in the world. Shortly afterwards, he was replaced by Titan in November 2012 .

It achieves a Linpack computing power (Rmax) of 16.325 PFLOPS (16.32 quadrillion calculations per second). This makes it 1.55 times faster than the previously fastest supercomputer, the K computer with 10.51 PFLOPS. To provide this power, Sequoia needs 7.89  MW , which makes it one of the most energy-efficient systems on the top 500 list, not only compared to the K Computer (12.6 MW). This is achieved by the interconnection of 100,000 base PowerPC-A2- Blue Gene / Q - processors with 18 cores (cores 1,572,864) at 1.6  GHz as well as a further core for control and I / O. Its main memory is 1.6 PB
