Presentation Transcript

  1. Panda Production on LCG • ATLAS software • Releases in $VO_ATLAS_SW_DIR by AdeS • $SITEROOT must be used • TRFs also installed but no guarantee • Dynamic trf installation(same for Lexor) • Not homogeneous • requires matchmaking • pilot sanity checks

  2. LRC is LFC • Authorization via acls in virtual file system • Use /atlas/Role=Production, not /atlas/usatlas • Proxy must come from LCG trusted voms • T2 SE cleanup • removeT2 files on T1 exists • Will remove too much • “last time used” does not exist? • Not clear same method as for LRC will work • Want “oldest not needed by Panda”

  3. Cloud assignment • Must take N jobs per cloud from ProdDb • Just highest priority could lead to empty clouds • Must put cloud assignment back to Db • Protocol/Eowyn changes • Stage-in/out • Always close SE • lcg-cp and lcg-cr (atomic copy-registration) • Want dccp and lcg-cr

  4. Status • CA cloud in production • TRIUMF,Westgrid,Toronto,Alberta,UVIC • 1340 cpu slots filled • 3 smaller sites to come • Mostly running filler tasks • until seeded with Evgen • LCG lexor still active in CA, but discouraged

  5. Test jobs ran in FR and UK • Could start with crude pilot factory • but will start with autopilot • Will assign low priority tasks • FR keen and have DDM support • UK management will accept tests • less DDM support
