CITerra upgrade to take place in early December

The CITerra cluster will be  composed of 254 traditional computes nodes.  Each
has 12 cores and 4 GB of RAM per core.  The whole cluster will be connected with
a low latency, high bandwidth network called infinibad.  In addition to
the traditional compute nodes, it also will have 60 GPU based nodes with a total
of 180 Nvidia M2090 GPUs. The system is backed with a 720 TB raw Lustre
high performance parallel filesystem.  This filesystem can perform at
around 9 GB/s.  The traditional processors have a peak performace of 40
Teraflops and the GPU processors have a peak performance of 110 Teraflops.
