Tech Overview

Jetstream is designed for access whenever and wherever you need to analyze data.


Jetstream's interface is based on the Atmosphere cloud computing platform, and extended to support science and engineering research. The operational software environment is based on the OpenStack cloud operating system. Globus integration simplifies and secures data transfer between Jetstream and other systems.

The computing environment consists of two homogenous clusters at Indiana University and TACC, with a test environment at the University of Arizona. The system provides over a half PetaFLOPS of computational capacity and 2 petabytes of block and object storage.

VM host configuration

  • Dual Intel E-2680v3 (Haswell)
  • 24 physical cores/node @ 2.5 GHz (hyperthreading on)
  • 128 GB RAM
  • Dual 1 TB local disks
  • 10GB dual uplink NIC

Jetstream leverages 40 gigabit Ethernet for network aggregation, and each of the production clusters connects to Internet2 at 100 Gbps. This physical distribution means the system will be highly available and resilient even in an event that makes one of the two sites inoperable.
