06/06/2023 EuroCC Training - Performance-aware C++ programming

6 June 2023 - Performance-aware C++ programming 


The C++ programming language is a systems-level language pervasive in many areas including scientific computing. This complex language provides users with a multitude of approaches to solving complex tasks, but not all programming paradigms or approaches are equal in terms of performance.

Accelerating Machine Learning: Tim's Journey with Supercomputer LUMI

LUMI Supercomputer
Tim Lebailly, a PhD student at the PSI Group in KU Leuven, is working on advancing machine learning algorithms for AI through self-supervised learning. To handle the large datasets required for training, Tim utilizes supercomputing resources, particularly the LUMI supercomputer. LUMI enables parallel processing of massive image datasets, reducing training times significantly. Tim's experience with LUMI has been positive, providing him with the ability to conduct multiple experiments simultaneously, overcome challenges with AMD GPUs, and benefit from the support and communication facilitated by the LUMI team. The power of LUMI empowers Tim's research, paving the way for breakthroughs in self-supervised learning for vision-based industries.

Puxano: matchmaking, mapping industry challenges to research

User Story Mpacts: leveraging expertise

Spatial sorting and the effect on the computational time
Besides computing infrastructure, VSC also offers a wide range of services to its users. One of these services is helping users to improve their software so it can run more efficiently on the VSC infrastructure. In the case of Mpacts, VSC recommended sorting the particles so that particles close in (simulated) space are also close together in computer memory. This programming technique made the software more efficient and, thus, faster.
