  1. Gluex Data Challenge 2 Production on the Open Science Grid Richard Jones

  2. Production overview

  3. Wall time daily usage

  4. Usage on Fermilab site

  5. Usage on the Purdue site

  6. Usage on the Northwestern site

  7. Usage on the UConn site

  8. Production site summary

  9. Finding the inefficiencies Wall-clock-weighted job success rate

  10. Digesting these results • 450k files (14TB) now globally available online from UConn via srm • Virtually none of the inefficiency came from srm (non)availability • Jlab has started pulling dc2 files from UConn to archive on the mss • Substantial inefficiencies exist at several sites • Under study, one site at a time • Production works, even if there are remaining inefficiencies • More Gluex sites are needed to improve production stats
