Pilot jobs working group of the Technical Forum (wiki)
Support of Multi-user pilot jobs (MUPJ) for LHC VOs
In December 09, the WLCG Management Board asked the WLCG Technical Forum to provide recommendations on the use of multi-user pilot jobs, in particular on the deployment and configuration of glexec and its usage by the experiment frameworks.
- Document that describes what pilot jobs are, their benefits, disadvantages and other aspects that sites and experiments may need to be aware of, is available here : https://wlcg-tf.hep.ac.uk/wiki/Multi_User_Pilot_Jobs (IGTF certificate required)
- "Traceability and Logging" and "Grid Pilot Jobs" policies available at http://www.jspg.org/wiki/JSPG_Docs
- Questionnaire for site admins : https://wlcg-tf.hep.ac.uk/wiki/Multi_User_Pilot_Jobs#Questionnaire
- See T2-T3 Technical Meeting, January 22
- Pierre Girard's presentation (restricted access to t2t3 group)
- Collective answer from sitessent to Maarten Litmaath has been attached to the meeting agenda as well (restricted access to t2t3 group)
- MUPJ in principle supported
- Most of the sites/resources compatible with glexec setuid
o many sites require it in the medium terms
o strongly preferred by CMS and ATLAS
- Many sites prohibit bypassing glexec on internal errors (with some tolerance for the time being)
- Proposed course of actions :
