Tuesday 17th July


Monday 10th July

  • The EGI RP/RC A/R Report for June 2017 is available on the following link.
  • GPU queues. We had a query on GridPP-Support about sites providing these queues and how to use them. Help requested.

Monday 3rd July

  • July 2017 GDB and pre-GDB. Draft agenda available. Container technologies working group pre-GDB contact Gavin McCance to get involved.
  • Winnie: Do sites need lcg-CA installed?
  • EGI: Usage of ops VO. Is anyone still using it for UK tests?
  • June T2 reports:
    • ALICE
      • All okay.
    • ATLAS
      • Lancaster: 84%:85%
    • CMS
      • All okay
    • LHCb
      • Lancaster: 83%:84%
      • Oxford: 70%:100%
  • The agenda of the WLCG ops meeting held on Monday is available.


Monday 26th June

  • GOCDB has received a new service type request for: ‘eu.egi.storage.accounting’: - authorising the site/SE to publish the storage accounting data - making the site/SE appear in the portal - monitoring that the accounting data are regularly published.
  • The registration to the next LHCOPN/LHCONE meeting is now open. LHCONE meeting agenda: https://indico.cern.ch/event/646629/.
  • HEPiX Fall 2017 meeting will be held at KEK, Tsukuba, Japan, from 16th to 20th October. HEPiX registration page: http://hepix-fall-2017.kek.jp/registration.html.
  • Chris B: Gotcha when upgrading ArcCEs to htcondor 8.6
  • EGI: new nagios probes appdbsync and OCCI-Categories for testing cloud services
  • Dan: cvmfs versions. It seems others are running 2.3 and 2.4 versions.
  • LSST: submission from panda is now working at Lancs, Manc and RAL. The plan (only sketched for now) is to run a data challenge. GridPP is behind this and said we should give a high priority to this effort. At the moment the initial plan is to use 16,000 cores for a month. This is a significant chunk of resources and will require organisation and much testing to get it running smoothly. Though using panda LSST doesn't have all the resubmission features ATLAS has, they also use the storage tools slightly differently privileging xrootd which is not as well supported as gridftp.

Tuesday 4th July

  • A round of reminders is coming!

Tue 23rd May As part of the process of moving everything to Centos7 (or some other form of RHEL7), I've written up how we build nodes at Liverpool for our ARC/Condor system.

https://www.gridpp.ac.uk/wiki/Centos7_Adoption

I hope it's also a decent cheatsheet for Puppet3/Hiera. It's a draft, and I need to put in some more details, but it should be usable.

Tue 7th Mar

I want to get rid of following stale docs...

  • Ten Easy Network Questions
  • GridPP Answers to 10 Easy Network Questions
  • SL5 status
  • Glasgow Middleware Operations Logbook
  • London Tier2 Shares
  • 23rd June 2010 Special Topic: NGS Technical Roadmap - Pete Gronbech
  • SAM availability: Monthly summary table
  • Transfer Tests Birmingham Endpoints
  • EVO Tips and Tricks
  • BaBar: bbrbsub270

Monday 13th Feb

  • Please check the keydocs page. Would all owners please review their pages and prepare a short note on how they will bring things up-to-date in the coming months. This will be discussed at a core ops meeting (poll to be circulated shortly).
  • There are several EGI operations document updates out for review. Please make comments to Jeremy by 20th Febraury for inclusion in the UK feedback:


Monday 30th January

The fusion VO has been removed from GridPP Approved VOs.

Monday 9th January

  • Tom put these together:
    • A snapshot of the GridPP UserGuide is now available as an offline document in the Zenodo repository:
    • ...and the v1.0 release of the LaTeX code used to compile it is here.
    • There are some minor differences (mainly hyperlink-related) to the online version [1], which has also had a v1.0 release here.


Tue 22nd Nov

  • More on Accounting audit tools

The process for ARC, Toque and VAC is now documented here.

Tuesday 2nd May

  • Generally quiet. A few low availability tickets.
Rollout Status WLCG Baseline

Monday 13th February

- This includes notifying of (inter)national services that will have an outage in the coming weeks or will be impacted by work elsewhere. (Cross-check the Tier-1 update).

Tuesday 4th July

  • Pete C is preparing another networking forward look document. Note that figures presented in the Manchester workshop were for a Tier-2 (not always a single site).

Tuesday 6th June

  • An update from the DIRAC workshop? GridPP is still the only true multi-VO instance, so we will continue to see issues with this. release quality of dirac has improved within the past year. gfal2/EL7 problems seem to be coming to an end after being cooped up with all authors for 3 days on end. The Imperial GridPP module now has integrated testing. It was also noted that every dirac instance has it's own special module to adapt to their community on top of main dira. We are trying to push as much of out special functionality back into the main dirac branch.

Tuesday 25th April

  • perfSONAR version 4 was released on 17th April. Sites with auto-update on should have been automatically upgraded. Note perfSONAR 4.0 requires more CPU than previous versions as a result of some of the increased functionality. Full details here
  • Duncan has recreated the UK perfSONAR mesh. Link here!


Tickets

Tuesday 18th July 2017, 10.00 BST

34 Open UK Tickets this week. Last minute look at the tickets as I was off yesterday!

Waiting for Reply from LHCB
124052 - Glasgow Job-Publishing Ticket
129312 - RALPP ARC CE Ticket
Both of these tickets are waiting for LHCB feedback.

Atlas Multi-core Job Problems?
129054 - Sheffield
129593 - Oxford
Whilst the symptoms are a little different, could there be a link between these two atlas tickets?

Storage Accounting Tickets
A quick note that all 6 of these tickets are chugging along nicely, with only the Liverpool figures still "under scrutiny". There's a plan involving keeping them open.
