I am attending this week the Open Source Grid and Cluster conference in Oakland, California. This event includes GlobusWorld, Sun Grid Engine workshop, and Rocks workshop, as well as tracks on other open source grid and cluster software.
As an organizing committee member, it is always a little nervewracking ahead of a meeting, wondering how it will work. We're now in the third day and I am please to say that the meeting is going very well. The sessions are well attended and there is lots and lots of discussion and questions, both during and between talks. (At this very moment, I am in a session that is running 15 minutes over as attendees miss the break for a demonstration of Taverna and Globus.) In addition, the Marriott in Oakland turns out to be a beautiful location.
For those not fortunate enough to be at the meeting, the talks are being made available online.
