University of Wisconsin at Madison Migration to SL5 James Bellinger University of Wisconsin at Madison 14-Apr-2010 14-Apr-2010 1

Systems “Go” Validation argued and agreed last week Tools work Devil in details: Reconfiguration: new product to hold current versions of checkrel, etc for all new releases No details yet for selecting farm OS CafGui doesn’t work Drop? Make part of a package to be picked up by all new releases? (Kick can down the road a week or three) Can we announce tomorrow? 14-Apr-2010

What is missing? What sorts of infrastructure changes do we have to make now? Date for end of further ports Timetable for returning radon 14-Apr-2010

Non-release CDF software Lots of things not in a standard release that give grief in SL5 Neurobayes (commercial) JointPhysics Non-SRT makefiles User code Will be residual support issues for a while 14-Apr-2010

External products Need to review which bring along baggage Neurobayes v1.8b wanted gcc 3.4.3 compiler! Partial list from Lynn and StDenis http://www.hep.wisc.edu/~jnb/cdfcode/current/ ExternalProducts.xls 14-Apr-2010

Proposed Priorities Finish new releases for SL5 Development needs to compile Get official statement on lifetime for analysis support. Unofficial is 10 years, but data access costs money. We have obligation to provide… Set up a test bed with a stricter compiler; estimate project to make code compliant Team looks at patch differences between MC, production, and Stntuple; estimate project size 14-Apr-2010

Timeline Today Last week’s timeline 14-Apr-2010 Announce 15-Apr?

The future OS migration End of 2011+10(??) years = end of 2021(??) What is official lifetime? Will we still have SL5 farms? If Yes, we’re done here If No we’ve got some more work, and should do it before we lose experts Maintenance Bug fixes, help installing, odd glitches, explaining that we don’t support installation on Macintosh, etc Joint Terminal Release Xrootd+large file support ease data-handling effort Reduce patch maintenance and expertise required But will anybody use it? 7-Apr-2010
