This talk will give a broad overview on the fitting that we're doing in
HEP. On one hand, the talk will cover the variety of fits in HEP, the
different needs and types of inference as well as efforts for
serialization and standardization. On the other hand, the relevant
libraries will be covered, that is zfit, pyhf, hepstats iminuit and
Python packages like SciPy and how they work...

20. evermore: differentiable (binned) likelihoods in JAX

Manfred Peter Fackeldey (RWTH Aachen University (DE))

27/08/2024, 10:32

I'd like to present evermore (https://github.com/pfackeldey/evermore) that focusses in efficiently building and evaluating likelihoods typically for HEP. Currently, it focusses on binned template fits.
It supports autodiff, JIT-compilation and vectorization of full fits (even on GPUs).

18. b2luigi — bringing batch 2 luigi!

Alexander Heidelbach, Jonas Eppelt (Karlsruher Insititute of Technology (KIT))

28/08/2024, 09:40

Workflow managers help structure the code of pipelined jobs by defining and managing dependencies between tasks in a clear and easy-to-understand fashion. This abstraction allows independent tasks to be automatically parallelised more independently of computing systems. Additionally, workflow managers help keep track of different tasks’ outputs and inputs.

b2luigi is an extension of the...

22. End-to-end workflow automation: updates of the luigi analysis workflow package

Marcel Rieger (Hamburg University (DE))

28/08/2024, 10:00

Physicists performing data analyses are usually required to steer their individual, complex workflows manually, frequently involving job submission in several stages and interaction with distributed storage systems by hand. This process is not only time-consuming and error-prone, but also leads to undocumented relations between particular workloads, rendering the steering of an analysis a...

19. waluigi - Beyond luigi

Benjamin Fischer (RWTH Aachen University (DE))

28/08/2024, 10:20

Workflows for research in HEP experiments are not only quite complex but also require sufficient flexibility to adapt to changes in structuring, conditions, methodologies, and research interests. This holds especially true in the physics analyses extracting the results and measurements.
Here, the use of workflows systems, specifically Luigi, have shown to be of great use to manage and...

14. File synchronization between Linux systems in Python with yarsync

Yaroslav Nikitenko

29/08/2024, 09:25

Yet Another Rsync is a Python wrapper around a well-established Linux tool rsync with a simple and familiar interface of git. Python allows us to create a higher-level instrument, which is safer and sometimes more efficient than the original binary.

While many data analysts today heavily use databases and rely on cloud computing, other approaches have also their benefits. Many...

13. Architectural framework for data analysis Lena

Yaroslav Nikitenko

29/08/2024, 09:45

The term «architecture» in software has numerous definitions. Ultimately it defines whether your analysis code will be extensible and maintainable. We propose an architecture based on the functional style and separation of data, logic and presentation. It is implemented in a free software framework Lena.

Lena is a general data analysis framework in Python, named after a great...

16. FCCAnalyses: A Framework for Future Circular Collider Physics Performance Studies

Juraj Smiesko (CERN)

29/08/2024, 10:05

Physics performance analyses provide essential input for defining detector requirements in the Future Circular Collider (FCC) project. To streamline these analyses, we employ FCCAnalyses, a software framework built on top of the ROOT DataFrame.

Among the functionalities offered by the FCCAnalyses are:
* Standard set of RDataFrame EDM4hep functions: Events can be analysed directly in the...
