Grid Technology Interim gLite release process
• EGEE project finished on April 2010• EMI project started on May 2010• Until EMI (and EGI) are able to take care of the releases
there is a transition period where:– WLCG is the driving force behind the gLite releases until EMI takes
over– We will try to keep LCG and EMI related work as much aligned as
possible
• How long ?
– The first EMI release is scheduled for March-April 2011

• No final decision was taken
– From the SL4 roadmap http://www.scientificlinux.org/news/archive/roadmap-sl4 :• SL 4.0-4.8 : Obsolete in October 2010 • SL 4.9 : Minimal support (security only) until February 2012
– We would like to reduce the effort on gLite 3.1 but we need some official list of what needs to be supported
