Let's BOINC!    


How would you like to do something that really feels good? Something that costs you nothing and actually contributes to important scientific projects? 

If that sounds like fun to you, then I suggest you click on over to the BOINC Project at http://boinc.berkeley.edu/. BOINC stands for the Berkeley Open Infrastructure for Network Computing. It's an easy-to-use interface that links your computer, along with thousands of others, with one or more research projects of your choice that require enormous computing capacity but can't afford to buy time on a supercomputer.

By dividing computations into lots of small pieces and distributing those pieces to hundreds of thousands of small computers to work on when they would otherwise be idling, BOINC creates an amazingly powerful virtual supercomputer, of which your desktop, laptop or even your PlayStation can be a part. You can do this individually, or, just to add to the fun, join an existing team or create a new one.

As I write this, BOINC has 573173 computers humming away, with a combined capacity of 5.552 petaflops. (A petaflop is a million billion--10 to the 15th--floating point operations per second.) That makes the BOINC network three times faster than the world's current fastest stand-alone supercomputer, the Cray XT5 Jaguar. Not bad for a bunch of volunteers!

In a few minutes you can download BOINC to your computer and chose from among 36 projects that tap into the BOINC network. These cover a remarkable range of scientific challenges, including helping CERN's Large Hadron Collider determine stable orbits for the particles it's accelerating and smashing together (LHC@home), detecting gravitational waves from neutron stars (Einstein@home), studying the evolution of our home galaxy (Milkyway@home) or of the entire universe (Cosmology@home), figuring out how best to stop the spread of malaria (Malariacontrol.net), protein structure and function (Rosetta@home), comparing climate models (Climateprediction.net), and dozens of others.

I've picked two so far--Einstein@home, looking for gravitational waves, and SETI@home, looking for technologically-created signals from outside our solar system. A few minutes after I stop working at my laptop, one of these programs automatically starts up. If I wander by after a bit I'll find one of their colorful displays on the screen, along with an indication of how much calculational support I've contributed to that product so far.

The next two on my list are Malariacontrol.net and either Milkyway@home or Cosmology@home.

BOINC-ing turns out to be ridiculously easy, fun, and it lets me contribute effortlessly to important scientific research. What more can I say except let's BOINC!
