What makes a grid perfect for one project, but a cloud better for another? When is a high-performance computer wasteful overkill, or a small cluster underpowered?
To answer these questions, iSGTW has invited experts from around the world to join us on Wednesday, 14 July 2010 at 10:30 a.m. CDT/4:30 p.m. CEST for a one-hour live chat - and you're invited.
Can't make it to the chat? No problem. For a week following the chat, an even larger host of experts will join us in our online forums to answer questions. To volunteer to serve as an expert, please email us at editors@isgtw.org.
We'll be announcing the identity of our experts throughout the week by adding them to this page. But in the meantime, we'd like to offer you a preview of some of the experts you can expect to hear from next week.

Philip Blood
Senior Scientific Specialist, PSC
Advisor to Campus Champions, TeraGrid
Philip Blood received his Ph.D. in Bioengineering from the University of Utah in 2008 where he used massively parallel molecular dynamics simulations to study how proteins remodel cellular membranes. In 2007 Blood joined the Pittsburgh Supercomputing Center as a Senior Scientific Specialist in the Scientific Applications and User Support group. He currently works with scientists in the fields of computational chemistry, biophysics, and various other disciplines to advance science through supercomputing. Philip has recently taken a leading role in TeraGrid's Campus Champions program, an effort to help more researchers at U.S. institutions take full advantage of TeraGrid resources.
