MORE HORSEPOWER FOR AC3’S LINUX CLUSTER

Dell AC 3 Linux cluster 187 node.

AC3'S Linux cluster：

 ac3’s Dell Linux cluster has been upgraded with an
additional 32 nodes, increasing the number to 187,providing processing power around 1.25 teraflops.
The additional nodes were acquired with ARC funds for the CUDOS Centre of Excellence, to provide dedicated
computing capacity to the Centre.

 ac3 Dell Linux Beowulf Cluster (Barossa) is a 187-node Linux cluster consisting of
     374 Pentium IV Xeon CPUs running at 3.06 GHz.
    
   The theoretical peak performance of the cluster is 2.20 teraflops (flops, floating
  point operations per second), and a measured performance reached approximately
  1.1 teraflops; this was measured on the initial 155-node configuration, which was
  later extended to 187 nodes.
