Blue Gene

Blue Gene is currently (January 2007) the fastest computer in the world.
Le project is cofinanced by the Département of the Energy of the United States and is developed by IBM.

It had already held the record of the September 16th 2004 with the October 26th 2004 (in a not finalized version), with 36,01 will téra Flops with the test Linpack. The record was previously held by NEC Earth Simulator of 35,86 téraflops. Blue Gene itself was exceeded by the supercomputer Columbia (42,7 téraflops) before taking again the advantage, the same month, with 70,7 téraflops (32  768 processors with 700 MHz). It has from now on a comfortable advance thanks to its 367 téraflops (record carried out with 131.072 processors).

Context

Several machines exist from now on in the world, Blue Gene being the first supercomputer with being marketed and produced in several specimens. A machine Blue Gene was in particular ordered by the organization Astron , with the Netherlands, ends of astronomical research - LOFAR. 3 computers Blue Gene (October 2006) are classified today among the 10 most powerful computers of the planet (source: top500.org)

Characteristics of BlueGene/L (last MAJ at 2/22/07 JR UTEC)

  • 1 megawatt
  • 1  024 adapters Ethernet (1Gb/s each one)
  • ASIC integrating two embarked controllers PowerPC 440, a subsystem of Mémoire hiding place and one of communication: 131.072 Processors (February 2007).
  • random access memory: 16 To of the type GDR
  • storage capacity: 400 To
  • Operating system: Unix/AIX
  • current Power (February 2007): 360 téraflops.

Use of the machine

  • To simulate in real-time foldings up of Protein S (see prion) within the Genetic framework of research in .
  • Dated mining intensive on medical Statistiques with large scales to discover the correlation S of them hidden
  • Analyze in real-time of radioastronomic signals within the framework of research on the origin of the universe
  • Blue Brain Project - simulation of a cortical Colonne human.

A repercussion will be probably also a certain satisfaction for the community Linux, and some specific references for the manufacturer of the machine, IBM.
