Review status of SRM v2 and Space Tokens

• See also MinutesMay2SpaceTokens
• srmcp - have we given up entirely?
• Next version of dcache may not require srmcp.
• Upcoming release of dCache may not require srm - but the one that uses dccp.
• Pilot still needs work. And other Panda developments.
• All we can do is keep the old
• AGLT2 - ATLASDATADISK - tested; 90 TB
• SLAC - tested; 50 TB
• BU - tested; 160 TB RAW
• SW - setup, not tested; 60 TB
• MW - working still.

RSV-SE probes

• Xin - has tested RSV-SE probe in the new release, running on the SRM door node; works. Reports correctly to the RSV collector at the GOC. srm-ping, srm-cp
• Would like to use existing infrastructure on OSG 0.8 gatekeepers.
• for SRM-dCache - probe is ready.
• for Bestman-xrootd - a minor issue needs to be resolved. Wei thinks won't be a problem. Sites will need to upgrade their bestman-xrootd. Wei will follow-up with Arvind and Alex.

CCRC08 news

• Managed centrally - need to communicate the four endpoints that are ready to Stephane and Alexei.
• Make sure old CCRC08 data is deleted - mainly for free space.
• 10 TB is the minimum

Next procurements

• Standing agenda item, see CapacitySummary.
• No news

LRC modifications for user data deletion

• See SiteCertificationP5
• Heads-up minimal testing. AGLT2 trying it out now - Hiro sending additional information. Send feedback to Charles for official instructions. Gridsite must be enabled.

Analysis Queue Update

• Analysis workshop next week at Argonne
• Auto-site selection now working well - Marco's testing.
• FDR1 reprocessing status? "This week", but nothing started.

Operations: Production (Mark, Kaushik)

• After the dCache upgrade at BNL, there were issues with Panda Mover. US cloud was basically off. Issues cleared up on the BNL side.
• On-going push to get last sites to autopilot. Transitioning BU last - all looks okay.
  • Next on list will be MWT2. Waiting for Paul - one of wrapper scripts need changes for dCache sites. Hopefully by end of week.
  • Then Tier3's
• There may be pile-up jobs requiring lots of input files - that take only 30 minutes to run, but hours to stage input files. Not much we can do.
• Bit of a backlog

Operations: DDM (Hiro)

• http://www.usatlas.bnl.gov/dq2/monitor - development stalled, will monitor space used by users.
• DQ2 site service upgrade status/plan
  • Follow-up: 0.6.6 - no word from Miguel. Old version is not updating the dashboard very well.
• Concerned about space at BNL - but new storage is coming online soon.

RSV --> SAM (Fred)

• Please see this link: http://www.usatlas.bnl.gov/twiki/bin/view/Admins/MonitoringServices
• Follow-up status:
  • All sites are in the RSV monitor.
  • On SAM side, waiting to resolve uta.edu versus swt2.org. Not an issue at the UTA site; assuming being handled at GOC.
• For AGLT2-muon-calibration FTS channel - still need to report through BNL? Answer - yes.

Throughput initiative - status (Shawn)

• News from Monday's meeting - see notes.
• Monalisa and configuration links:
  • http://gridtest01.racf.bnl.gov:8081/display?page=network - https://svn.usatlas.bnl.gov/svn/usatlas-int/load-test/Control/conf/network_m2m
  • http://gridtest01.racf.bnl.gov:8081/display?page=gridftp - https://svn.usatlas.bnl.gov/svn/usatlas-int/load-test/Control/conf/gridftp_d2d
• Nearly all sites performing well with iperf
• Some asymmetries seen in the load test measurements, under investigation.
• Fixed problem of not properly killing iperf process.
• Please send graphs to Shawn for next week's meeting.

Site news and issues (all sites)

• T1: Hiro reports that storage is tight. Adding a 16 TB thumper today. Main implication is for FDR data and CCRC data transfers. Will be resolved by tomorrow.
• AGLT2: all okay; some cpu drop at midnight last night.
• NET2: all okay; SRM v2 up and running; still waiting from IBM a 10G replacement.
• MWT2: all okay; running into some scaling issues with addition of new nodes (number of tcp sockets, etc). Upgraded all head nodes recently.
• SWT2 (UTA): all okay; 1 day shutdown on 21st for electrical work on distribution panels.
• SWT2 (OU): working on 10G cards and routing tests for the external network. FTS problems reported by Yuri? (Hiro thinks a minor problem.)
