HIGH PERFORMANCE COMPUTING† USAGE BY SCHOOL/DEPARTMENT CY2003
HIGH PERFORMANCE COMPUTING* USAGE BY SCHOOL/DEPARTMENT CY2003
†Use of parallel supercomputers, PC clusters, and distributed computing cycles for computationally intensive research needs, including simulations and modeling.

Bandwidth available to researchers (in megabits or gigabits per second)
  • WL Campus: 10-1,000 Mbps
  • Intrastate***: 10 Gbps
  • WL to regional campuses: 45 Mbps
  • Interstate****: 40 Gbps

DATA STORAGE CAPACITY AND UTILIZATION
DATA STORAGE CAPACITY AND UTILIZATION

 

*Includes all university-owned desktop/notebook computers and workstations in labs, offices, classrooms, research facilities, etc.

**Increase is primarily due to inclusion of residence hall computing labs, the Digital Learning Collaboratory, and academic area additions.

***Using 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.

****The National Science Foundation funded TeraGrid infrastructure, a multi-year effort to build and deploy the world's largest, fastest, distributed infrastructure for open scientific research, has 40 Gbps in available bandwidth distributed at several national TeraGrid sites, of which the Indiana University-Purdue University Grid (http://purdue.edu.teragrid.org/) is one.
