      1)  Upcoming events and contributions from our WG:

      • GDB meeting:  April 12th
        • Working group status update
        •  GDB is informed that the work is in progress, but the time scale is too short to give a definitive recommendation.
        • A longer discussion will take place during the WLCG Workshop (see next point)
      • HEPiX Spring 2017 Workshop, 24-28 April 2017, Budapest (Hungary)
        • Summary report about the WG activity
        • in addition: a number of talks from other members of the WG (e.g. from A. Sciaba')
      • 2017 WLCG Workshop (University of Manchester) 

      2) Next WG meeting (April 7th) will be dedicated to the review of the results for the GDB report

      • Expect short report from all experiments’ representatives 
        • Statement about the correlation of DB12 and the experiment applications (sim, digi, reco)
        • Approach (in place or suggested) to enable reproducible studies of correlation among experiments’ workloads and next generation of benchmarks (HepSPECxx)
          • Document procedures, possibly share code (e.g. via CVMFS) of test applications


      3) Documentation and Action list    

      • A number of new sections have been introduced in the twiki
        1. Information needed to run passive benchmark  https://twiki.cern.ch/twiki/bin/view/HEPIX/CpuBenchmark#Passive_Benchmark
        2. Available resources for benchmarking activity (CERN, GridKa)
        3. DB12 Vs python version  
          • summarised already in email thread, now is in https://twiki.cern.ch/twiki/bin/view/HEPIX/DB12VsPythonVersion
          • need to reach a conclusion about this aspect: do we need to fix the python version to run DB12?
      • For the site representatives and the experiment representatives: Please remember to fill the information in our Twiki https://twiki.cern.ch/twiki/bin/view/HEPIX/CpuBenchmark
        • Thanks to who already did it    

      4) AOB

      • Extremely interesting talk of M. Guerri last Friday at the IT Technical Forum:
        • Title:  "Understanding applications’ performance”
          • aka understanding (i) DB12 magic boost and (ii) Intel Haswell core performance
        • The slides and the recording are available in indico https://indico.cern.ch/event/612774/
