  1. Activity Management: what for? Antonio ReticoEGEE 08 Istanbul - 24 Sep 2008

  2. Question Why this talk? EGEE08 - Istanbul - 22/28 Sept 2008

  3. Because … Sites working in Pilots have already received a number of ‘tasks’ from the LCG Savannah tracker PPS Sites and ROCs have been bothered recently by several “administrative circulars” I sent out • Changes in the site registration procedure • Request to verify the correctness of a “site/activity registry” in a PPS webpage (www.cern.ch/index.php?dir=./panel/SVC/) I give here some answers to FAQs on these topics More and more questions welcome after the talk EGEE08 - Istanbul - 22/28 Sept 2008

  4. Question Aren’t the Savannah tasks an unnecessary complication of our day-to-day work? EGEE08 - Istanbul - 22/28 Sept 2008

  5. The purpose of the tasks The idea is to use completed tasks as logs of the effort spent in PPS activities throughout the regions Expected benefits: • ROCs can better monitor their PPS allocations • PPS partners can have a better idea of the actual cost of an activity before committing to it • better load balancing in the assignment of tasks • ... the 1000+ advantages of having good accounting records Ideally we would like all the PPS activities covered by formal tasks Several technical reasons to choose Savannah • Easy to link tasks with release objects (patches, bugs) • A well-populated user database (we are almost all there) • Libraries developed in EGEE to extract statistics from tasks EGEE08 - Istanbul - 22/28 Sept 2008

  6. The desired Output EGEE08 - Istanbul - 22/28 Sept 2008 Effort (in PersonXhours) spent in the regions for the Cream Pilot

  7. Other views EGEE08 - Istanbul - 22/28 Sept 2008 Distribution of effort in time for DECH ROC (Cream Pilot)

  8. Other views EGEE08 - Istanbul - 22/28 Sept 2008 Distribution of effort in PPS by Service Area

  9. More on tasks The effort credited for each task is pre-defined • Values referenced in the PPS Service Description (https://twiki.cern.ch/twiki/bin/view/LCG/PreProductionServiceDescription ) The task owner can change it if needed The re-actualisation of the task “values” will be useful in future planning and assignments The data model supports different weights for tasks related to different middleware services (currently not applied) EGEE08 - Istanbul - 22/28 Sept 2008

  10. Question How do you represent with tasks the supply of a continuous service? (e.g. submission of SAM tests) EGEE08 - Istanbul - 22/28 Sept 2008

  11. Extremely good question Service contributions, such are the operation of a general-purpose support service are associated to integrated “service tickets” Service tickets: • Task: run the service X for 1 month • Start: January • Due: February • Effort: 8PH Soon after closure you receive another “timesheet” for March EGEE08 - Istanbul - 22/28 Sept 2008

  12. Question Why do we need yet another registry for PPS? EGEE08 - Istanbul - 22/28 Sept 2008

  13. Non-homogeneity of PPS sites Traditionally, we used the GOCDB as registry for PPS sites. This is not sufficient with the introduction of “Pilot Services” as a new PPS feature The “logical” PPS may include resources at production and pre-production sites (identified by the BDII they use and the GOCDB flag) • Rough distinction: PPS sites are used mostly for deployment test, production ones mostly for pilots To group them together, we needed either a new flag in GOCDB for all sites or a separate registry. We opted for the 2nd EGEE08 - Istanbul - 22/28 Sept 2008

  14. Comment AAARRRGHHH! You duplicate information !! EGEE08 - Istanbul - 22/28 Sept 2008

  15. Nope The pieces of information stored in the PPS registry mostly deal with mapping of sites (or teams) with pre-defined work packages in PPS (specialties) Used for: • Creation and assignment of tasks • Quick identification of candidates for staffing new pilot services More info eventually imported from external sources • GOCDB  Site contact info • gLite repository  Service list GOCDB still the master for site info • No changes in site registration procedure for ROCs • The site/activity mapping in the PPS registry is currently performed by the PPS coordinator at PPS–registration time EGEE08 - Istanbul - 22/28 Sept 2008

  16. Question Who maintains the registry? EGEE08 - Istanbul - 22/28 Sept 2008

  17. Maintainers of the registry Currently the registry is centrally maintained in the jurisdiction of the ‘PPS Support’ Area with mandate from the ‘PPS Coordination’ Technically run by CERN_PPS staff on behalf of ‘PPS Support’ (in other words, it’s me ) EGEE08 - Istanbul - 22/28 Sept 2008

  18. Question Isn’t that a step towards centralisation as opposed to regionalisation? EGEE08 - Istanbul - 22/28 Sept 2008

  19. Ahaha! I knew you’d’ve asked The whole activity management framework is under development Externalisation still premature (but I am looking forward to it) An adequate authentication and authorisation mechanism still needed • I envisage an organisational structure similar to the VOMRS “representatives” Before extending the tool let’s see if the principle works EGEE08 - Istanbul - 22/28 Sept 2008

  20. Question What am I supposed to do in order to work in pre-deployment testing of gLite-DPM? EGEE08 - Istanbul - 22/28 Sept 2008

  21. To become a pre-deployer Make sure you are in a PPS site • GOCGB.ProductionStatus=PPS • if not you need to register one through your ROC Inform the MPS Coordinator (or whoever in pps-support@cern.ch) and ask to be registered for pre-deployment of the DPM Wait for testing tasks to arrive and follow them up EGEE08 - Istanbul - 22/28 Sept 2008

  22. Question What if I want to be involved in a pilot of WMS? EGEE08 - Istanbul - 22/28 Sept 2008

  23. Registration for pilots (MPS) You still have to register for the activity To register means to commit to contribute in the eventuality a pilot be started Pilots are rare, so you might be idle for long periods before receiving tasks Sites willing to work in PPS with continuity should subscribe also to work packages within MQS and Support EGEE08 - Istanbul - 22/28 Sept 2008
