Wider VO issues

From GridPP Wiki
Jump to: navigation, search

This is part of the core operations team activites

The task involves:

1. Tracking new VO requests across the Grid and specifically those affecting UK resource providers.

2. Maintaining the extracts and details at: http://www.gridpp.ac.uk/wiki/GridPP_approved_VOs.

3. Tracking the status and problems experienced by the VOs and raising issues to the weekly ops-team meeting - Site enablement problems - User issues

4. Providing (or coordinating) help and support to new VOs who require guidance on becoming grid enabled.

TODO list

* Good practice
 * For individual users of regional VOs
 * for medium sized VOs
 * An example data model
  - Use checksums
  - Custodial copies of data  
  - Keep multiple copies for load sharing and resilience
    - Sending jobs to data
  - Catalogue synchronisation (Use LFC)
    - Sensible paths on storage
    - DFC?

* VOMS
  - Use of roles
  - SaroNGS is now obsolete with the demise of NGS, but was an interesting way of making things easier. 

* How to do stuff
 - Submitting jobs to data

 * Job submission

* Ganga
 - Stuff for small VOs. 

* Dirac

* FTS3 - and webFTS

Comments to Chris at HEPSYSMAN:

  • reliability
  • easy of use
  • future proofing - LHC VOs dictate directions (e.g. move to CREAM, away from LFC)
  • WLCG stack is not complete (holes for data management etc.)
  • Hidden features

    • try not to lose portal and console developments in NGS (worked better with gram on CEs)
    • free to support SARONGS in the UK
  • Had ngs for a long time but little real work submitted. Should NGS sites have UI point at GridPP WMSes?
  • Config changes break things inc. certificates. VO specific tests. What is Nagios support like for multi-VOs?
  • Manage VO expectations
  • Site admins need to be proactive -> raising VO issues to say TB-SUPPORT or proxy GGUS tickets
  • What about other solutions like boinc?
  • Typical use cases - should VOs define this when joining?
  • Repository of images for middleware. UI. Use of CVMFS.
    • Observation of people taking up instructions (feedback). Config UI is complicated. Open UI?

UI with GSI ssh route - but then who to support?

Done

* Resilient VOMS servers
