KTH, ParaTools, the University of Oregon, and ENCCS (EuroCC National Competence Center Sweden) have joined forces to organize a hybrid workshop dedicated to performance monitoring with TAU and E4S on LUMI Supercomputer and Cloud HPC platforms from 29 to 30 October 2025. The event brings together code developers, researchers, and research software engineers to exchange ideas, share best practices, and explore innovative approaches to performance monitoring and software management across supercomputers and cloud platforms.
The workshop features a series of sessions covering topics such as the TAU Performance System, the E4S project, and techniques for performance evaluation on both the LUMI supercomputer and commercial cloud infrastructures. Participants will also gain hands-on experience with the instrumentation of MPI and GPU (ROCm and CUDA) applications, performance data management using TAUdb, and analysis tools such as ParaProf and PerfExplorer. Additional sessions will focus on containers and package management with E4S, deployment of E4S tools on cloud HPC environments, and AI workflows using Jupyter Notebooks, Codium, PyTorch, JAX, NVIDIA NeMo, and BioNeMo.
Although theoretical optimization of complex code has its limits, major breakthroughs in scientific computing have been driven by sophisticated performance analysis tools. Advances in massively parallel systems such as LUMI and cloud-based HPC platforms now allow researchers to study complex phenomena with unprecedented precision. To fully exploit these powerful systems, reliable tools for monitoring, debugging, and managing software are essential - empowering the development of applications that drive progress in science, industry, and society.
