Disclaimer • Accounting Review was discussed during the currently ongoing CMS Offline and Computing week and these are preliminary notes taken by me that summarise CMS feedback Preliminary notes from the running CMS O&C week 3
Accounting Portal • CMS uses the accounting portal to prepare the CRSG reports twice per year Development portal used for T 1 accounting as it included multicore • • Minor fixes were still needed to get proper values • • This needs to be improved since T 2 s are also moving to multicore Production portal used for T 2 accounting • • It was much worse in previous exercises Difficult to say whether single core numbers were correct since the difference was smaller If it would be easier to prepare these reports, CMS may find it useful to prepare them more often for internal use CMS would like WLCG to help correlate Accounting portal data with CMS dashboard data • Dashboard values reported by CMS are taken from the Framework Job reports, written by each job after running Preliminary notes from the running CMS O&C week 4
Accounting Reports • CMS doesn’t seem to be using these reports Preliminary notes from the running CMS O&C week 5
Multicore accounting See feedback on slide 3 • CMS agrees to push development portal to be moved to production if this improves the quality of the numbers • Preliminary notes from the running CMS O&C week 6
Opportunistic resources • It would be good it WLCG defines what it is opportunistic resources in this context • • T 3 s? Non pledged resources in T 1 s/T 2 s? Commercial clouds? CMS agrees that in any case accounting portal should report everything that CMS uses • • It could be beneficial to show funding agencies the percentage of opportunistic resources used by CMS Accounting portal should be the primary source of information to report about opportunistic usage to WLCG Preliminary notes from the running CMS O&C week 7
Space accounting • There will be a dedicated presentation about CMS use case at the pre-GDB Preliminary notes from the running CMS O&C week 8
REBUS is use for pledges • There is a general agreement in CMS that capacity information is useful if it is correct and can be trusted • • • Useful also if sites could rely on the storage systems themselves instead of the sys admin to report about storage capacity in a reliable way A missing functionality is to know when information changes in REBUS • Although this functionality could be moved to the new IS if pledges are also included there Preliminary notes from the running CMS O&C week 9
