System Architecture

Eagle is configured to run compute-intensive and parallel computing jobs. It is a cluster comprised of 2604 nodes (servers) that run the Linux operating system (Red Had Linux or the derivative CentOS distribution), with a peak performance of 8 PetaFLOPS.

The nodes are connected to each other and to storage by a high-speed 100Gb/s EDR InfiniBand network. All nodes and storage are connected using an enhanced 8-dimensional hypercube topology that provides a bisection bandwidth of 26.4 terabytes/s.

Eagle has Network File Systems for home directories and application software as well as a 14 petabyte high-speed Lustre file system for parallel I/O.
