Existing Grids

Many grids exist already. Mostly for scientific computing.
- Access Grid. ANL.
- Information Power Grid- Nasa.
- Unicore
- TeraGrid- NSF.
"TeraGrid is a multi-year effort to build and deploy the world's largest, most comprehensive, distributed infrastructure for open scientific research. By 2004, the TeraGrid will include 20 teraflops of computing power distributed at five sites, facilities capable of managing and storing nearly 1 petabyte of data, high-resolution visualization environments, and toolkits for grid computing. Four new TeraGrid sites, announced in September 2003, will add more scientific instruments, large datasets, and additional computing power and storage capacity to the system. All the components will be tightly integrated and connected through a network that operates at 40 gigabits per second."
Dr. Kirk Cameron heads a laboratory which has recently joined the Grid.
