    Present: Augusto, Guilherme, Enrico, Stefan, Kim, Enric, Danilo, Jim, Philippe

    Actions:

    Danilo: communicate to Augusto way to change the compilation flags in cling

    Augusto: try out pyROOT

    Hydra:

    - The differences between aclic/g++ and interpreted are understood. It is nice to see aclic and compiled examples having the same timing!

    - Hydra works quite well with ROOT: macros were included in Hydra too.

    Round Table

    PyROOT

    - Conversion of contiguous memory to numpy array implemented

    - Conversion of datasets into numpy tables

    - TDF is exploited and therefor ImplicitMT used during the conversion!

    Parallel Writing

    - Test fixed

    - Remove the merging thread
