With many researchers relying on ROOT's fitting framework RooFit for the fits of their statistical models to data there is a need for this framework to be both fast and user friendly. Recently, significant efforts were made to improve in both of these directions. For increased fitting speed a novel gradient-based parallelisation framework was built to supersede the already existing...
The statistical model is an extremely information-dense and
comprehensive representation of a physics measurement, which is
why efforts to preserve and publish it have been pursued for
years. One of the main challenges is to find a format in which to
store a statistical model that is useful for people external to
the experimental community and not bound to a specific
software (such as...
RBrowser is new web-based widget in ROOT combines objects and files browsing with different kinds of objects displays.
Separate library is used to provide browsing capability for file system, ROOT collections, content of TFiles and TTrees. With a little effort, custom classes and collections can be implemented.
RBrowser user interface implemented with OpenUI5. Different kind of web-based...
REve is a migration and extension of the 15-year old TEve for ROOT-7 and web-based graphics. Cling allows for experiment-independent implementation of physics data-collection interfaces and table-views. R&D work has been ongoing for almost 4 years and REve is now approaching the stage where it can be used to implement certain visualization applications. Main design ideas and development...
The unprecedented volume of data and Monte Carlo simulations at the HL-LHC will pose increasing challenges for data analysis both in terms of computing resource requirements as well as "time to insight". Precision measurements with present LHC data already face many of these challenges today. I will discuss performance scaling and optimization of RDataFrame for complex physics analyses,...
