Software TIM in Glasgow

Description
This second ATLAS software technical interchange meeting (TIM) will follow on from the very successful Berkley TIM on November last year. We will look at ongoing framework developments, strategies for algorithm parallelism and progress in infrastructure modernisation. All of these discussions map out how our software will evolve in the next few years towards Run3. As before the meeting will be discussion-rich, rather the full of talks and also to have room for discussion of more radical solutions and possibly disruptive changes. We plan general plenary sessions for the first few days, followed by dedicated breakouts and hackathons later in the week.

      Hackathon - Algorithmic Migration 323

      323

      University of Glasgow
      Speakers: Charles Leggett (Lawrence Berkeley National Lab. (US)), John Baines (STFC - Rutherford Appleton Lab. (GB)), Scott Snyder (Brookhaven National Laboratory (US)), Vakho Tsulaia (Lawrence Berkeley National Lab. (US))

      this session will include discussions on:

      • migrating serial Algs to cloneable Algs
      • writing re-entrant Algs
      • sharing data between clones
        • explicit sharing vs merging at finalize
      • I also want some feedback on how we should deal with Histograms in cloned Algs
        • each clone gets its own hist? how to merge?
        • clones share a hist, and do locking themselves?
        • clones share a hist, and the THistSvc manages the locking?
      • PROPOSAL:
        • default behaviour of THistSvc is each clone gets it's own copy. histograms in clones are moved to memory resident. primary algorithm must explicitly call THistSvc->merge(id) during finalize to have cloned histograms merged into it
        • new method THistSvc::regSharedHist, which will create a shared instance of the Histogram for all clones
          • during execute, clients MUST lock histogram before manipulating it:
          • auto lockGuard = THistSvc->getLock(hist);
          • unlocked automatically when goes out of scope

       

      Tomasz: we have to sum more frequently online i.e. before every publication
      and TDAQ has implementation for it:

      Speakers: Charles Leggett (Lawrence Berkeley National Lab. (US)), John Baines (STFC - Rutherford Appleton Lab. (GB)), Scott Snyder (Brookhaven National Laboratory (US)), Vakho Tsulaia (Lawrence Berkeley National Lab. (US))

      This session could include:

      • CaloHive in athenaMT
      • Extend ID experience to migrate first Muon algo(s)
      • Implementation of Arrays of Handles / optional Handles
      • Can we manage without UpdateHandle? How to deal with collections that are not relevant to scheduling
      • Creation of IDC in views

      Notes:

      • Array of Handles: Agreed to add these (Charles)
      • UpdateHandles: Alternatives found for use cases discussed
        • Update common pattern in muons, simplest solution is copy.
        • PixelAmbiguitiesMap (axample showed by Adam) not needed.
      • Trigger use-case for offline data preparation: Add RegionSelectorSvc to InDet data preparation algorithms (trigger-specific configuration)
      • Scheduler & decoration: Use case: algo1->A->algo2->A*->algo3 Need solution to ensure algo3 is scheduled only after decoration (A*).  Need DecorateHandle that creates alias for decorated collection?
