Hardware
 
  by Frezza-Buet Herve
 
 

We have considered a panel of technical solutions for the cluster. First argument is the efficiency of shared memory and MPI executions, but other factors, as energy, have also been studied. We have retained the following hardware :

  • 256 nodes composed of 128 bi-PC "Carri Systems HighServer SR1520ML", with for each 2 independent compact PCs. Global energy is reduced, compared with mono-PC machines. Each of these PCs has
    • a bi-core Xeon 3075
    • RAM 4Go, cache 4Mo
    • a hard drive.
  • CISCO 6509 switch with
    • high speed matrix
    • CPU card (10GBits complient)
    • 6 ethernet cards, with 48x1GBits ports.
