The computing environment consists of two homogenous clusters at Indiana University and Texas Advanced Computing Center (TACC) with a test environment at the University of Arizona. The system provides over ½ a PetaFLOPS of computational capacity and 2 petabytes of block and object storage. The individual nodes contain two Intel "Haswell" processors, 128 GB of RAM, 2 terabytes of local storage, and 10 gigabit Ethernet networking. The system leverages 40 gigabit Ethernet for network aggregation and each of the production clusters connect to Internet2 at 100 Gbps. The physically distributed system allows Jetstream to be highly available and resilient. GlobusAuth is used for large-scale file transfer and authentication.
