Instructions are here. Current OS versions here. Duncan has recreated the UK perfSONAR mesh. Link here! Tickets Monday 21st May 2018, 14.00 BST 43 Open UK Tickets this week. Sites getting Ticket Updates? We've had two anecdotal tales of sites not getting emails updates to some tickets (135139 at Lancaster and 134945 at RHUL). Has anyone else not been getting emails about their tickets? NGI 135038(9/5) The yearly review of our gocdb information. Everyone did check that their site (and their own) details were correct, right? (I had my old office phone number listed). Jeremy is proceeding to the NGI level review now. In progress (21/5) SKATELESCOPE.EU TICKETS QMUL: 135042 CAMBRIDGE: 134980 Both these tickets appears to be waiting for submitter/VO input, and perhaps are solved. BRISTOL 135121 (15/5) 135120 (15/5) I'm not sure what's going on with the dates on these, but both ROD tickets were submitted by Kashif last week and both are still in the assigned state at time of writing. Assigned (15/5) Update - these tickets have been fielded now- thanks! 134820 (29/4) This CMS pledge enquiry was answered, so I think it's waiting on CMS input. The ticket likely needs a prod to stir the pot. In progress (1/5) MANCHESTER 134684 (23/4) One of the "please upgrade perfsonar" tickets, this is waiting for an answer from Duncan. Waiting for reply (4/5) DURHAM 134687 (23/4) Also a perfsonar upgrade ticket, any progress with this? In progress (30/4) IMPERIAL (kind of) 134567 (17/5) I think this Pheno corrupt file cleanup ticket is nearly completed, it just needs to be kept an eye on to make sure it doesn't hang around after it's done. In progress (17/5) QMUL 132929 (18/1) After re-reading Adrian's last post I think there's a request for information in there to help debug things from the apel side. In progress (10/5) TIER 1 135133 (15/5) Chris has asked the ECHO admins to look at this CMS ticket, after seeing some odd behaviour. In progress (17/5) 133992 (12/3) This other ECHO related ticket, from atlas, looks like it has badly stalled. Is there still an active issue to fix? In progress (19/4) Tools - MyEGI Nagios Monday 20th November The WLCG dashboard is available here: http://dashboard.cern.ch/. Please review the results on Steve's test pages. Tuesday 18th July Following our ops discussion last week, Steve will focus his tests on supporting the GridPP DIRAC area and decommission the other tests. VOs - GridPP VOMS VO IDs Approved VO table Monday 20th November Tom Whyntie has requested (and been granted) access to the GridPP VO to get some pipelines working for large-scale processing and analysis of MRI scans associated with the UK Biobank project. All VOs in the incubation page being prompted for updates by the end of November (required input for OC documents). QMUL (Steve L) is following up on the biomed MoU. GridPP want to be cited in research papers for the support our resources/sites provide. Impact Citation policy (https://www.gridpp.ac.uk/acknowledging.html) Site Updates Date
