Ever have a problem where one supercomputer just isn't enough?
Researchers simulating such extreme problems as worldwide weather changes often reach the limits of even the largest computers.
To solve the problem, NASA has helped to create the concept of a computational grid. A computational grid is a network of geographically and often organizationally distributed resources including computers, instruments, and data. A user has single-sign-on access to all the resources on a grid.
Currently the three most substantial grids, in terms of compute cycles already provided, persistence, and scope of resources, are:
The NASA Information Power Grid (IPG), which connects several NASA centers, makes available supercomputers, high-end scientific instruments, and terabyte datasets.
As grids grow, grid communities will be looking for scientists and computer engineers to help build grids or to use grids for research. The NASA Advanced Supercomputing (NAS) Division at Ames Research Center is a focal point for the joint university and government creation of NASA’s IPG.
