Supercomputer Architecture

Vers la version Française
Version Française

From November, 2003 to November, 2009, the University had a machine IBM, Regatta p690 containing 32 processors (Power4) for a theoretical power of 218 GFlops.


Today, the Computing Center counts a computer cluster for parallel calculations and a server dedicated to  sequential calculations.

Listed below are the specifications of the supercomputer at the University de La Réunion.

IDENTITY

  • BULL
  • Model : Novascale R422 – Novascale R423
  • Name : ccur
  • Operating sytems : RHEL Cluster Suite, X BULL Advanced Server

CLUSTER SERVERS

  • 20 compute nodes each with 2 x 2 Intel Xeon processors quadcore 2.26 Ghz and 24 GB of memory
  •  1 compute node with 2 x 2 Intel Xeon processors quadcore 2.93 Ghz and 72 GB of memory
  •  1 compute node with 4 Intel Xeon octocore 2.26 Ghz and 132 GB of memory (this additional server were installed in september 2010)
  • 2 nodes for the connection of users and for management of the cluster

All compute nodes are interconnected with InfiniBand.
Theorical performance is 1.92 TFlops with 200 cores.
