Grid computing has been used to perform about 420 years worth of work in just four months. 

The Wisdom (World-wide In Silico Docking On Malaria) project, which ran from October to January, analysed about 80 000 drug compounds an hour, searching for a drug that will combat malaria.
Altogether more than 140-million compounds were processed on up to 5 000 machines, with the results – 2 000Gb of useful data – expected to speed the search for an anti-malaria drug.
The computers in the grid ran open source grid software, gLite, which allowed them to access central grid storage elements which were installed on Linux machines located in several countries worldwide.
