The Extremely LarGe Advanced TechnOlogy (El Gato) cluster is a high performance computer jointly funded by the  National Science Foundation and the University of Arizona. The El Gato project is a collaboration between members of the University of Arizona Department of Astronomy, the School of Information: Science, Technology, and Arts, and the University Information Technology Services.

El Gato uses specially designed hardware to achieve high performance economically, including NVIDIA K20X GPUs and Intel Xeon Phi 5110p Coprocessors. The system is designed around Intel Ivy Bridge CPUs, large amounts of memory per node (256GB/node), and FDR Infiniband. The system is also connected via FDR Infiniband speed to a DataDirect Networks SFA 12K petabyte-scale storage server.

Users of the El Gato system must, as a condition of using the system, acknowledge the NSF grant that funded the system in any resulting publications. The acknowledgment text can be found here.
