Brian Paul Bockelman (University of Nebraska-Lincoln (US)), Philippe Canal (Fermi National Accelerator Lab. (US))

Attendees: Philippe, Jakob, Oksana, Danilo, Guilherme.

Oksana: Landed a PR.  I have been focusing on CMake side and thus still pending another PR on fastcloning.
I have 2 posters both on I/O (compression).  CMake is getting better to achieve better modularity build.  The most complex is to treat properly external dependencies.    In  particular I need to be able to exclude the search for external dependency that are not needed (by the set selected by the user).   (ACAT start March 11, rehearsal on March 3rd).

Jakob: Away from this week.   Going on the focus on RForest next week.

Danilo: RAS, waiting for an example of corrupted file that crash RDataFrame (and problably TTreeReader) but does not crash TTree::Draw nor SetBranchAddress.

Guilherme: Working on performance on CMS data analysis example.  Still need to fix TTree::Fill allocation of TBB arena.  Something strange is TTreePlayer.
