Hi Winnie I am replying on TB-SUPPORT not the GridPP-USERS list as I think this is a question more relevant to other sysadmins than UK users. The CREAM CE has still not met the criteria put in place to indicate when it is accepted (https://twiki.cern.ch/twiki/bin/view/LCG/LCGCEtoCREAMCETransition ) to replace the LCG CE. Therefore it is not recommended. A couple UK sites have played with the basic CREAM CE - perhaps those involved could respond to the list with their observations?

A while back the concensus seemed to be CREAM-CE was problematic or just didn't work. Has it improved? Any UK sites had experience with or using CREAM-CE? Is it stable/fine or still not yet ready for prime time? ldapsearch AFAICS shows only 2 sites using it: GlueForeignKey: GlueClusterUniqueID=cream-ce01.marie.hellasgrid.gr GlueForeignKey: GlueClusterUniqueID=cream-ce.pdc.kth.se wl / got -5 min to waste time if CREAM-CE is borken -- Scanned by iCritical.
