"World Community Grid (WCG) is an effort to create the world's largest public computing grid to tackle scientific research projects that benefit humanity... Using the idle time of computers around the world. World Community Grid's research projects have analyzed aspects of the human genome, HIV, dengue, muscular dystrophy, and cancer. The organization has so far partnered with nearly 400 other companies and organizations to assist in the work and has over 410,000 registered user accounts," says Wikipedia.

Have a look at their website http://www.worldcommunitygrid.org for more details about this IBM supported distributing computing project where we can contribute the idle/ unused processing power of our computers for global good.

World Community Grid engages in a number of research projects, to which we can contribute to. Details of those projects can be cound here:
