Nicholas M. Glykos' group
Our main computing machine (shown below) is Norma, a stateless Beowulf-class computing cluster comprising 96 cores, 82 Gbytes of physical memory, and 8 CUDA-enabled GPGPUs distributed over 11 nodes on a gigabit interconnect. See this more detailed description of the machine if you want the gory details.

The machine is used almost exclusively for molecular dynamics simulations and computational crystallography. The current cluster activity (or otherwise :-) can be accessed from here.
