• There are changes being made to the way the APEL infrastructure runs, and other Grids publish to it.
• These should be of interest to sites but not the MB.– Include ARC, Unicore, Globus– Local jobs from CERN
• See tomorrow’s GDB for details.
Changes to APEL
LCG
4
• The layout of graphs and the colour schemes have changed
• This was a complete internal rewrite so watch out for changes in behaviour and report them,
• More flexible graphics– Bugs have been raised about the labelling on the
graphs.• Query interface returns XML
– Allows saving query and programmatic interface– Needs documenting– See the custom interface
Changes to the Accounting Portal

• Accounting records for cpu used by batch jobs are published in several ways to the central APEL Repository.
• This is the worldwide repository for the LHC VOs.
• It publishes summaries of the data to the Accounting Portal @ CESGA where it can be dynamically queried and a number of standard reports produced.
Brief Summary Of Features
LCG

• Njobs, cpu, wallclock, normalisedcpu, normalisedwallclock, cpuefficiency,
• As a table, graphs, and download• Tables and graphs of one of above, download of all.• Any timespan of months.• Any VO, all, or a selection• Trees for Countries, NGIs, T1, T2• Display any point in the tree and below from top to
site level.• Date, VO, (Site/Region/Country) as a function of
one of the others.
Can View:

• Reports:– T1– T2 including pledges
• Views– User – see your own jobs– VO Member – see FQAN in VO (top 10)– VO Manager – see UserDN in VO (top 10)– Site Admin – see UserDN at site, FQAN just
added.

• T2 VOs• Ticket about a T2 reporting use by a VO to whom
they didn’t pledge. Poor efficiency a reputational risk to the VO.
• T2 Tree shows ALL VOs at T2 sites.– Can select but default is all LHC.
• T2 Report only shows pledged VOs– Did agree to show installed capacity but no progress
• Personal opinion that two views cover the use cases. Only the T2 report should reflect badly on T2 or VO.
Issues
LCG
11
• See ALL UserDNs, not just top ten. – (VO Manager)
• See ALL FQANs, not just top ten – (VO Member)
• See ALL Users (site admin)• Select a specific UserDN• Drill down on userDN and FQAN to see
sites.• ?????????
