Volunteer computing is a low-cost way to increase the computing power of science portals. In this approach, groups of jobs submitted to a portal are executed on the desktop and laptop computers belonging to portal participants or to the general public. We are adding this capability to HUBzero by integrating it with BOINC, a middleware system for volunteer computing. I will explain how BOINC works and how it meshes with Rappture, the application framework used by HUBzero.

Dr. David P. Anderson is a Research Scientist at the University of California, Berkeley. He directs the BOINC project, which develops middleware for volunteer computing. Dr. Anderson received graduate degrees in Mathematics and Computer Science from the University of Wisconsin, Madison. His research interests include volunteer computing, distributed, real-time and multimedia systems, computer graphics, and computer music.
