Please visit the website at Harvard Medical School for more information. It is that time again! The OSG Consortium All Hands Meeting! This very "collaborative" venue provides current and prospective OSG members, users and partners with an opportunity to talk through the activities and problems, lessons learned and future plans for the Open Science Grid Consortium. The All Hands Meeting will be held March 7-10, 2010 at Harvard Medical School IL. An OSG Council meeting will follow in the same location on March 10-11th. As usual additional related meetings will be co-scheduled with the All Hands Meeting. This should be an exciting time for the US LHC with the systems being used once again for real data processing: The US ATLAS Facility meeting and US CMS Tier-2 and Tier-3 meetings will both be held early in the week. On Monday we will continue the tradition to have 1/2 day workshops on specific topics - please contact any member of the Executive Board if you have requests for one of these. Any suggestions on speakers, discussion fora, BOFs etc are welcomed also. On Tuesday afternoon there will be a session where you can set up a demonstration of an application, technology or other activity that you would like to share with your colleagues (the "Electronic Demonstration Session"). You are invited to submit an abstract for this session. We will make available a table, chair, power strip, wireless network connection and a 17" screen. Slots for this session are limited to about 10. The program committee will make the selection of which demonstrations to include based on the abstracts, by March 1st. With your input and participation we look forward to another good meeting!
