London Tier 2 consists of the following Tier 2 grid sites:

UKI-LT2-UCL-HEP Please use mailing list (lcg-admin@hep.ucl.ac.uk)
UKI-LT2-IC-HEP Please use mailing list (lcg-site-admin at imperial.ac.uk)

Notes:

  • If you want to target all London sites you can use the following requirement in your jdl:
    Requirements = Member("GRIDPP-LT2", other.GlueHostApplicationSoftwareRunTimeEnvironment);
  • UKI on the CERN gridmap.
  • GStat2 for GRIDPP.

Contacting Sites

The preferred mechanism for contacting London sites is GGUS since it allows to track the issues. Please make sure to set the site name in the subject line.

  • If you have a request for London in general please contact the London Tier2 Manager
  • If you want to have a direct contact with the site admins please use the emails in the table above.


Supported virtual organisations (VOs)

  • We currently support approximately 20 VO in London.

This place is a good starting point.


Development and Testing

WMS

Imperial is an Early Adopter for the EMI WMS, QMUL for Storm.
See also: Staged Rollout

Monitoring

We have developed a monitoring tool called Grid Load that allows to see the number of jobs in any given state. For more details please see the Readme.

Real Time Monitor

Unfortunately, with the demise of the WMS it doesn't quite show the state of the grid any longer: Real Time monitor.

Blog

This is the place to look for day-day news (though sadly somewhat neglected these days). The blog is at http://londongrid.blogspot.com/. We also give an rss feed for the blog.

Experiment Involvement

CMS

  • CMS Activities in London are lead by D.Colling.

Security

Configuration Tips

  • Daniela's lovingly maintained archive of installing all things grid (if you need a password to see my siteinfo.defs, please email me).
