Home. What is grid computing? Although "the Grid" is still just a dream... grid computing is already reality.
Imagine several million computers from all over the world, and owned by thousands of different people. Imagine they include desktops, laptops, supercomputers, data vaults, and instruments like mobile phones, meteorological sensors and telescopes... Now imagine that all of these computers can be connected to form a single, huge and super-powerful computer! This huge, sprawling, global computer is what many people dream "The Grid" will be. "The Grid" takes its name from an analogy with the electrical "power grid". Let's compare an electrical power grid with the dream "Grid": "The Grid" doesn't yet exist in this form; however, the world already has hundreds of smaller grids... WLCG - Welcome.
