------ Forwarded Message From: Michael Ernst <[log in to unmask]> Date: Wed, 12 Aug 2009 07:48:56 -0400 To: <[log in to unmask]> Cc: Rob Gardner <[log in to unmask]> Subject: [Usatlas-grid-l] SL5 migration Dear Colleagues, Now that computing management of all four LHC experiments have signed off on the migration to SL(C)5 the WLCG management asks all Tier-1 and Tier-2 sites to carry out the transition as soon as possible. Following the migration of the U.S. ATLAS Tier-1 center about two weeks ago numerous validation tasks of various kinds were run by ADC central operations and have proven that the ATLAS software is in a state allowing ATLAS computing management to confirm readiness for an SL(C)5 based processing infrastructure. At our weekly computing meeting later today we will address this point in detail.

It was understood in the meeting that the experiments are all ready and able to use SL5 resources. A web page is available to provide pointers to the relevant information to support the migration, including links to the necessary packages. (https://twiki.cern.ch/twiki/bin/view/LCG/SL4toSL5wnMigration) It is now expected that Tier 1s and Tier 2s should plan this migration as rapidly as possible, so that the majority of resources are available under SL5 as soon as possible.
