GridKa School is a one-week summer school for grid computing and e-Science. It is arranged by the Steinbuch Centre for Computing (SCC) of the Karlsruhe Institute of Technology (KIT, the cooperation of Forschungszentrum Karlsruhe GmbH and Universitaet Karlsruhe), together with the project "Sustainable Grid Infrastructure" (SuGI, which is part of the D-Grid initiative), the HGF Alliance "Physics at the Terascale", and the project 'Enabling Grids for E-Science' (EGEE). In addition. Topics of the school are taken from the scopes of these and other projects and beyond. About 50% of the school consist of hands-on tutorials and workshops, giving participants the possibility to gain actual expertise on different kinds of middleware, applications and techniques. Because these tutorials are offered in parallel tracks, GridKa school practicals cover topics well suited for beginners, experienced users and grid administrators. The high grade talks and presentations give an up-to-date overview on important and interesting grid subjects. The program is completed by a 'get together' event (incl. a guided tour of the German WLCG Tier-1 center 'GridKa'), a school dinner, a poster session (students are encouraged to present their work) and a grid security workshop; the later is targeted at administrators. Applicants from all scientific and industry disciplines are welcome to apply online at www.fzk.de/gks09; the full preliminary schedule is listed on this homepage. Before July 31st, registrants can take advantage of an early bird discount. The organizing team reserves the right to limit the number of participants, if necessary.
