  1. Analysis framework news A.Gheata 27 June 2011

  2. Alien plug-in • Added support for processing runs with more than 20K chunks (where find –x command fails) • Producing collections with 15K entries max (find –l 15000 –o start) – then merge collections • Completely transparent • Incompatible with SetNrunsPerMaster(n>1) if there are big runs in the list.

  3. Support for task metadata • What for: Support for describing how to run a given task • Location of AddTask macro, libraries needed, handler type, utility tasks (e.g. physics selection, centrality, or tender)… • Embed this info in a class (e.g. AliAnalysisTaskConfig) • Able to read/write from root or text file • The plug-in could read one or more such modules (e.g. from OADB) and generate the train steering macro • This may give more flexibility and modularity in future • This approach is based on some recent discussions for automating the train procedure that is being looked into • Ideas, suggestions welcome

  4. Analysis trains operated by PWG • Purpose: test and operate physics trains according a central schedule • To change the balance between chaotic and organized analysis • To allow planning according priorities and share the production-related responsibilities with PWG • Long-standing blockers existing in Savannah • Tests with a minimal configuration already done, procedure documented but no train yet in production • Procedure for ~automatic testing implemented for PWG1 QA train (see Mihaela’s talk), but cannot be done yet for PWGn • PWG coordinators are kindly asked to take action
