08:50 → 08:55 ROOT6: the quest for performance

Speaker: Danilo Piparo (CERN)

Slides CHEP2015_ROOTPErf.txt

08:55 → 09:15 The ROOT 6 Runtime

Speaker: Axel Naumann (CERN)

The ROOT 6 Runtime 
 

ROOT 6 can do all of C++ - thanks to its interpreter cling which in turn is based on the industrial strength compiler llvm / clang. With the transition from CINT to cling, all the runtime type information infrastructure (the well known "dictionaries") had to be adapted, too.

This contribution will explain how the binding of user and experiment classes to ROOT currently happens and how this binding is migrated to C++ modules. It will also present these modules in the context of the upcoming C++ standards, where they are seen as a way to accelerate compilation time by factors. The presentation will showcase the advantages of using a compiler as an interpreter back-end and introduce the current areas of development for the interpreter.

09:15 → 09:35 Using R in ROOT with the ROOT-R package

Speaker: Lorenzo Moneta (CERN)

Slides abstract_chep2015_rootr.rtf

09:35 → 09:55 New developments in the ROOT function and fitting classes

Speaker: Lorenzo Moneta (CERN)

Slides abstract_chep2015_fitting.rtf

09:55 → 10:15 Clad - Automatic Differentiation Using Cling/Clang/LLVM

Speakers: Lorenzo Moneta (CERN), Vasil Georgiev Vasilev (CERN)

Slides abstract_chep2015_clad.rtf

10:15 → 10:20 ROOT 6 and beyond: TObject, C++14 and many cores.

Speaker: Philippe Canal (Fermi National Accelerator Lab. (US))

Slides Chep2015-ROOT.pdf

10:20 → 10:25 Base ROOT reference guide on Doxygen

The ROOT reference guide is part of the code. Classes description, methods usage, examples etc... are all embedded with the code itself. Doxygen is the reference model allowing to extract the documentation from such self described system. The ROOT documentation requires the development of specific tools (scripts) in the Doxygen context. The proposed project is these tools writing.
