11:00 → 11:01 Ops meeting minutes

* This is a reminder that this is an important task. The minute taker gives access to the discussions for those not present and provides a reference for others to refer back to afterwards. * The team composition has been changing. If everybody contributes then the task comes around less often. * From the start of GridPP4+ those in fully funded GridPP positions will be expected to contribute. Others are welcome to volunteer! * The minutes should contain a list of who attended; apologies; note who took the minutes and highlight actions. * A count is maintained at https://www.gridpp.ac.uk/wiki/Operations_Team_Action_items. * After uploading minutes to the agenda page the minute taker is expected to: ** Update the list of ops actions. ** Update their 'count' so the task can be shared fairly. Thank you for your support!

Due to the informal nature of this meeting, the minutes cover general topics which were brought up.

 

1) HEPIX is starting.

Currently, there's not much to discuss, as most of the talks which are up are Site Reports. 

Sam noted that there are some interesting talks in the second half of the week (on Clouds, Containers, HTCondor and future Storage), but most of the presentations are not up yet. There is an interesting talk (policy-wise) on CERN's batch system plans already up for the Friday.

 

2) Volunteer sites for HTTP Deployment TaskForce SAM test/beta-test. (Not widespread deployment, site needs to be prepared to engage with beta-testing the tests - determining false positives as well as debugging any issues it turns up)

 - Lukasz volunteered Bristol

 - Sam volunteered Glasgow

 - Ewan volunteered the Oxford IPv6 endpoint (as we're not sure if anyone else has an IPv6 only endpoint to use for testing)

* ACTION: Sam to email Oliver Keeble re these volunteers.

 

3) Only non-LHC VO update we have is Alessandra's on LSST. Ewan noted that the issue with non-publishing of pilot roles for LSST vo seems to be a General ARC Problem, and this is understood.

Sam gave a quick update on HPC DiRAC status (Lydia is about to restart some file transfers via FTS at RAL, but with a smaller number of transfers at a time). Ewan and Sam noted that the suggestion that an optimal mechanism for DiRAC would be to use tar files / diff tar files for "archiving" does not seem to be progressing with DiRAC at this time.

 

 

It was agreed that this discussion completed the useful list of topics to discuss (esp. with the small group present), so the meeting adjourned at this point.

11:01 → 11:20 Experiment problems/issues

Review of weekly issues by experiment/VO - LHCb - CMS https://cms-site-readiness.web.cern.ch/cms-site-readiness/SiteReadiness/HTML/SiteReadinessReport.html#T2_UK_London_Brunel See comment last week: https://twiki.cern.ch/twiki/bin/view/CMSPublic/SpaceMonSiteAdmin - ATLAS we are reconfiguring the ATLAS production queues to use DATADISK instead of PRODDISK in preparation for PRODDISK decomissioning. Progress can be followed here https://its.cern.ch/jira/browse/ADCSUPPORT-4335. -- Report from ATLAS week? - Other -- HPC DiRAC: Jens -- LIGO: Catalin -- LOFAR: George -- LSST: Alessandra Initial tests with Dirac have highlighted some problems. 1) Submission is very slow; 2) Similar jobs submitted in sequence get all submitted to the same site. As an aside Oxford and ECDF are not publishing the pilot role in the BDII which makes lcg-infosites progressively less useful. -- UKQCD: Jeremy - no update -- UCLan/GalDyn: Tom -- PRaVDA: Mark/Matt - GridPP DIRAC status -- http://www.gridpp.ac.uk/php/gridpp-dirac-sam.php?action=view
