Lens is a 77-node Linux cluster dedicated to data analysis and high-end visualization. Each of the
77 nodes contains four 2.3 GHz AMD Opteron processors. 32 of the nodes are configured with 64 GB of main memory, an NVIDIA 8800 GTX GPU with 768 MB of memory and an NVIDIA Tesla GPGPU with 4GB of memory. The other 45 nodes do not contain GPUs but are configured with 128 GB of memory. The primary purpose of lens is to enable data analysis and visualization of simulation data generated on jaguar so as to provide a conduit for large-scale scientific discovery. Members of allocated jaguar projects will automatically be given accounts on Lens.
