Topic:Automatisches Monitoring der Datenqualität von Photonen in Belle II
Summary: Belle II ist ein Teilchenphysikexperiment das unter anderem darauf optimiert ist, neutrale Teilchen wie Photonen zu messen. Um präzise Messungen und Suchen nach neuer Physik zu ermöglichen, muss der Detektor hierfür genau kalibriert werden. Wechselnde Beschleuniger- und Detektorbedingungen erfordern ein zuverlässiges und automatisiertes Monitoring der Energie- und Richtungsauflösung von Photonen. Im Rahmen der Bachelorarbeit soll Richtungsauflösung von Photonen in echten Daten bestimmt und automatisiert werden.

Topic:Automated process monitoring with workflow management software towards sustainable computing
Summary: In High Energy Physics many calculations are done on complex data. Since every calculation increases energy consumption, it is important to do these as sensible and efficient as possible. While some computing sites already provide data on the power usage of these calculations, it is still difficult to monitor the energy consumption of whole analysis workflows. In this project, an existing workflow management based on the software luigi will be extended to automatically collect data on the energy usage of its tasks.

Topic:Performance optimization for Machine Learning reconstruction algorithms
Summary: This thesis project centers on optimizing the performance of Machine Learning (ML) reconstruction algorithms, particularly focusing on Python algorithms and their integration with C++ interfaces for the high-level trigger at Belle I running on a large computing cluster. As a bachelor student, your primary objective will be to streamline the execution of ML reconstruction algorithms on CPUs and GPUs. You will explore techniques such as algorithm parallelization, memory management, and code optimization to achieve optimal performance in both Python and C++ environments. Through rigorous benchmarking and profiling, you will evaluate the impact of your optimizations on the reconstruction speed and resource utilization. By the end of your thesis, you will have contributed to the development of robust and efficient ML reconstruction pipelines, essential for high-level trigger systems in particle physics experiments.

Topic:Performance study of NN-Training with data streaming from remote storage
Summary: In High Energy Physics, datasets of several hundreds of GB are used for machine learning. Often, these datasets are stored at remote storage servers. Sometimes it is not possible to keep them on the computing machine. It could be an option to stream the data from the remote storage. It is possible to use a cache that keeps the data near the computing resource. That reduces the network traffic and the access latency for the files. The performance during streaming with and without cache should be studied.

Topic:Multi-core support for Belle II Grid
Summary: Belle II uses a distributed computing infrastructure called Grid. Currently, Belle II supports only one CPU core per application in the Grid. The use of multiple CPU cores would speedup applications and reduce memory footprint. You can improve the Belle II Grid computing by configuring, implementing, and testing the support for multiple CPU cores in the Belle II Grid.
