SDM Center All-Hands-Meeting


December 11-13, 2006

Perseverance Hall (Building 54, Room 130)

Lawrence Berkeley National Laboratory

Purpose statement

The focus of the AHM will be on identifying the data management needs of scientific application areas in the petascale regime that the SDM center should focus on in the next few years on. We hope to end up with an organization of our activities in the center around projects, where each project will be assigned technologies desired, people to do the work, and specific application people to work with.

We'll be dedicating the entire first day, Monday, Dec. 11, to hear from various application domains about their data management needs. The first half of the second day will be organized as brief presentations of technologies that the SDM center has developed and deployed over the last few years. The afternoon will be dedicated to working groups whose goal is to identify future joint projects with applications and technologies to be applied to them. The third day is planned for hearing summaries from the working groups, and forming Projects-by-Application teams.
