Hey Nation…I love hearing about how the internet evolves. Here is some crazy behind the scenes stuff. Posted by www.timesonline.co.uk:
A network of 100,000 computers providing the greatest data processing capacity yet unleashed has been created to cope with information pouring from the world’s largest machine.
The Grid is the latest evolution of the internet and the world wide web and computer scientists will announce on Friday that it is ready to be connected to the Large Hadron Collider (LHC).
Scientists at CERN, where the world wide web was invented, created the €500 million Grid because they realised that a single computer would not be able to cope with the amount of data the LHC is expected to produce each year – 15 petabytes, or 15 million gigabytes, which would fill 20 million CDs.
It is designed for schemes where huge quantities of data need crunching, such as large research and engineering projects. The Grid has the kind of power required to download movies in seconds, and the ability to make high-definition video phone calls for the same price as a local call. More importantly, it should help to narrow the search for cures for diseases. However, it is unlikely to be directly available to most internet users until telecoms providers build the fibre-optic network required to use it.
The Grid allows scientists at CERN, the European Organisation for Nuclear Research, to get access to the unemployed processing power of thousands of computers in 33 countries to deal with the data created by the LHC. They said that it was an extra facility laid on top of the internet, which originally linked computers around the world in the Seventies.
Dr Bob Jones, a CERN scientist, said: “The [world wide] web allows you to access information on other computers. What the Grid allows you to do is not only access the information, but make use of their computing resources and power.”
He likened it to the National Grid. Users would be able to tap into massive amounts of processing power, but the source of the power would change, depending on availability. Processing tasks will be distributed between 11 gateway computer centres in ten countries, including Britain, which will share them out between more than 140 sites. One of the first jobs the Grid will tackle is handling the raw data for CERN’s experiments into finding proof of the Higgs boson, the so-called God particle.
