IBM Sequoia

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

Application

The IBM Sequoia was developed for the National Nuclear Security Administration to explore new energy sources and to simulate and improve the service life of nuclear weapon systems in order to dispense with underground tests.

Specifications

With the announcement of the current Top 500 list 18 June 2012 at the International Supercomputer Conference in Hamburg ISC12 the IBM Sequoia rose from 17th place to first place the Linpack benchmark list the ranking of the most powerful computers in the world. Shortly thereafter, he was replaced in November 2012 by Titan. He achieved a Linpack performance (Rmax ) of 16.325 petaflops ( 16.32 quadrillion calculations per second). He is 1.55 times faster than the previously fastest supercomputer, the K computer with 10.51 petaflops. To provide this service, Sequoia requires 7.89 MW, which makes him not only as compared to the K computer ( 12.6 MW), one of the most energy efficient systems on the TOP500 list. This is achieved through the interconnection of 100,000 base PowerPC-A2-Bluegene/Q-Prozessoren with 18 cores ( 1,572,864 cores) at 1.6 GHz and an additional core for control and I / O. His memory is 1.6 PB
