Overview

The Extremely LarGe Advanced TechnOlogy (El Gato) cluster is a high performance computer jointly funded by the University of Arizona and the National Science Foundation. 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.

Getting Started

  • Any user with a UA HPC account can log into and use El Gato. If you have an existing account on the UITS HPC systems, you can log into and use El Gato immediately.
  • If you wish to connect to El Gato from off-campus computers, you will need to install and log into the UA VPN system. For instructions on the VPN system, see here.
  • If you do not have a UITS HPC account, please follow the instructions here to create one.
  • Once you have an account (and have logged into the UA VPN if connecting from off-campus), to log into El Gato simply
