  • Revision to the Tier 3 white paper, and a reference Tier 3 facility defined.
  • Analysis benchmarks demonstrated at increasing scale (100/200/500/1000 simultaneous jobs) at all Tier 2 facilities.

Site certification review

• SiteCertificationP5

Operations overview: Production (Kaushik)

• Follow-up on space token description assignments (PRODDISK, MCDISK, GROUPDISK, etc)
  • See http://www.usatlas.bnl.gov/twiki/bin/view/Admins/rsrc/Admins/MinutesJune11/t2storage-june08.ppt.pdf

Shifts (Marco)

Next procurements

• Standing agenda item, see CapacitySummary.
• Follow-up issues:
  • Storage capacity recommendations/guidance for the Facility (320 TB capacity, from Kaushik's model on MinutesJune11).
  • Revised WLCG pledges
• Specifications from Internet2 for network monitoring hosts (Rich)

User LRC deletion (Charles)

• Nurcan reports this is currently failing - Charles addressing this.

Analysis queues, FDR analysis (Mark)

• Follow-up:
  • Regular exercising of analysis queues over data sets, especially when there are new releases. Nurcan is doing this.
  • Mark and Nurcan will meet to discuss some systematic testing at the sites and will re-consider the analysis benchmarks.
  • Metric - define a standard for time required to process a standard dataset
  • Consider site availability monitor which indicates basic functionality indicating site-readiness; this would help users distinguish "site" problems for "user-code" problems.

Operations: DDM (Hiro)

• FDR2 data transfers:

LFC migration (John)

• SubCommitteeLFC
• LFC sub-committee meeting yesterday, see: LFCMeetJune24

RSV SE & CE probe update status (Fred)

• Follow-up from last week:
  • SRM probes needed for AGLT2, SWT2, NET2
  • AGLT2 - has 2.0 probes, just not enabled. Will run configure.
  • BU - has RSV 2.0 running, but not reporting. Saul will follow-up, will install OSG 1.0 by next week.
  • SW - need SRM probes. Did upgrade, but may not have enabled SRM probe.
  • BNL - why not reporting? Xin claims its reporting fine locally. Are they going into Gratia correctly? Fred will follow-up with Xin.
• See https://twiki.grid.iu.edu/twiki/bin/view/Operations/RsvSAMGridView for links to SAM and Gridview reporting consoles.

Scheduling maintenance downtimes with the GOC (Sarah)

• For scheduling downtimes, the OIM system: https://oim.grid.iu.edu/
• Any follow-up questions?

WLCG accounting

• http://t2.unl.edu/gratia/wlcg_reporting

OSG 1.0 (Rob)

• OSG 1.0 now released
• Completed at UC_ATLAS_MWT2, AGLT2
• See https://twiki.grid.iu.edu/twiki/bin/view/ReleaseDocumentation/WebHome
• Follow-up from upgrade schedule of last week:
  • AGLT2 - complete
  • NET2 - within the next week
  • UTA_SWT2 - perhaps next week or earlier
  • SWT2_CPB - probably 2 weeks away since there will be a major shutdown
  • SLAC - first needs to do xrootd storage upgrade; earliest end of this month
  • MWT2 - within the next week

Site news and issues (all sites)

• T1:
• AGLT2:
• NET2:
• MWT2:
• SWT2 (UTA):
• SWT2 (OU):
• WT2:

Carryover issues (any updates?)

Pilot upgrade for space tokens (Kaushik (Paul))

• A bit of development to do. Carry-over
• No results yet from tests at AGLT2.

Release installation via Pacballs (Xin)

• Follow-up
  • Progress - this morning to discuss this. Fred - hoping this week to have first set of pacballs installed in DQ2. Will test with some older releases on some test machines.
  • Need official naming scheme.
  • Get installed with a special Panda pilot job using the software role. Expect performance to improve.
  • Expect a couple of weeks of testing.
  • Goal to bring into production by end of the month (June).

Throughput initiative - status (Shawn)

• 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

Nagios monitoring subcommittee (Dantong)

• Available space reporting at all sites.
• Tomasz was organizing a meeting to test globus-job-run (?)

SRM v2 and Space Tokens (Kaushik)

• Follow-up issue of atlas versus usatlas role.
• The issue for dCache space token controlled spaces supporting multiple roles is still open.
• For the moment, the production role in use for US production remains usatlas, but this may change to get around this problem.

AOB

• none
