Bandwidth available to researchers (in megabits or gigabits per second)
  • WL Campus: 10-1,000 Mbps
  • Intrastate3: 10 Gbps
  • WL to regional campuses: 1 Gbps 
  • Interstate4: 40 Gbps

 

1Includes all university-owned desktop/notebook computers and workstations in labs, offices, classrooms, research facilities, etc.
2Use of parallel supercomputers, PC clusters, and distributed computing cycles for computationally intensive research needs, including simulations and modeling.
3Using I-Light (Indiana's Optical Fiber Network), Purdue and IU high performance computing resources form the Indiana Distributed Terascale Facility, which has ten Gbps in available bandwidth.
4The National Science Foundation funded TeraGrid infrastructure, which is a multi-year effort to build and deploy the world's largest, fastest, distributed infrastructure for open scientific research, TeraGrid has 40 Gbps in available bandwidth distributed at several national TeraGrid sites, of which the Indiana University-Purdue University Grid (http://www.purdue.teragrid.org/) is one.
