Description

Short abstract:
In the face of climate change and its undeniable threats to humanity, the urgency for transitioning to CO2-free or carbon-neutral energy systems is paramount. While the future of energy conversion will be largely dominated by renewable sources, such as wind and solar power, combustion technologies will continue to play a crucial role in meeting the world’s growing energy demands, especially in the near term. The expected rise in alternative fuels—such as biofuels, e-fuels, and green hydrogen—demands a deeper understanding of combustion processes to ensure cleaner, safer, and more efficient energy generation. Accurately simulating combustion, however, is a formidable challenge due to its inherently multi-physics nature, involving complex interactions between turbulence, chemistry, and multi-species flows.
This workshop will focus on advanced numerical methods for modeling and simulating combustion phenomena in high-performance computing environments. Participants will gain insights into cutting-edge techniques and numerical methods, covering topics such as combustion closure modeling, load-balancing techniques, soot formation, and more. The workshop aims to gather different research groups, providing a venue to exchange new ideas, discuss challenges, and expose this new research field to a broader community.

This introduction provides hands-on information about working with high performance computing (HPC) at the RWTH Aachen University’s IT Center for users of the CLAIX-2023 HPC system. It is the basis for the follow-up event PPCES 2026. It focus on CLAIX-2023, the cluster that has been installed end of 2023 at the RWTH Aachen University’s IT Center.
The workshop will follow the HPC Carpentry curriculum for “Introduction to High-Performance Computing” while providing specific information for the CLAIX-2023 system. It is designed for prospect users of the HPC systems installed at RWTH Aachen University. Contrary to prior years, the workshop focuses on hands-on experiences on CLAIX-2023 to deepen the knowledge transfer on working with HPC systems in research.
The first part (half-day) provides an hands-on introduction to working with the UNIX shell. It follows the Software Carpentry lesson on “The Unix Shell”. No prior knowledge is required to attend.
The second part (two half-days) builds on the knowledge on working with the UNIX shell and focuses on working with HPC systems, such as CLAIX-2023. It follows the HPC Carpentry lesson “Introduction to HPC”. This part of the workshop is also targeted at prospect users of our HPC systems and will provide first experiences on how to use the software and resource management system on CLAIX-2023. It will enable participants to select preinstalled software on the cluster and write basic scripts to execute it on the HPC system. You will particularly learn about the most important details on using CLAIX-2023. Those who use to run their computing applications on local machines will learn how to run those applications on the RWTH Compute Cluster provided the necessary software licenses are in place.
The third part (half-day) will provide an introduction to the JupyterHub Service at RWTH Aachen University as an alternative method to using HPC resources at RWTH Aachen University and will conclude with an overview and introduction on how to apply for computing time at RWTH Aachen University.
Generally, this event forms the foundation needed to take part in our more in-depth event PPCES and to help take decisions on which part of PPCES might be interesting for you.

More information & registeration

Description

Short abstract:
Big data and Machine Learning (ML) are driving comprehensive economic and social transformations and are rapidly becoming a core technology for scientific computing, with numerous opportunities to advance different research areas, such as combustion modeling. The combination of combustion applications with ML has already been applied to several Computational Fluid Dynamics (CFD) configurations. It is a promising research direction with the potential to enable the advancement of so far unsolved problems, thanks to the ability of deep models to learn hierarchically with little to no need for prior knowledge. However, this approach presents a paradigm shift to change the focus of CFD from time-consuming feature detection to in-depth examinations of relevant features, enabling deeper insight into the physics involved in complex natural processes.
This training is designed to provide a basic background on machine learning applications, highlighting some of the areas of the highest potential impact. Emerging ML areas that are promising for combustion modeling, such as reduced-order modeling advancements, versatile neural network architecture developments, as well as some potential limitations, will be discussed. The workshop aims to gather different research groups, providing a venue to exchange new ideas, discuss challenges, and expose this new research field to a broader community.

PPCES 2026
2026-03-16 - 2026-03-20 | IT Center, Kopernikusstraße 6, Aachen, NRW, 52074, Deutschland
in cooperation with

Parallel Programming in Computational Engineering and Science (PPCES)
March 16th – 20th, 2026

This one week event will continue the tradition of previous annual week-long events that take place in Aachen every spring since 2001. We will cover the basics of parallel programming using OpenMP and MPI in Fortran and C/C++ and a first step towards performance tuning. Furthermore, we will embrace current topics in machine & deep learning. Hands-on exercises for each topic will be included.
The contents of the courses are generally applicable but will be specialized towards the compute cluster CLAIX which is the current system installed at RWTH’s IT Center. It might be helpful to read through the information which is provided during the HPC introduction on February 9th-10th 2025.
Topics
OpenMP is a widely used approach for programming shared memory architectures, supported by most compilers nowadays. We will cover the basics of the programming paradigm as well as some advanced topics such as programming NUMA machines. The compute nodes of the RWTH HPC Cluster (aka CLAIX) contain an increasing number of cores and thus we consider shared memory programming a vital alternative for applications that cannot be easily parallelized with MPI.
The Message Passing Interface (MPI) is the de-facto standard for programming large HPC systems. We will introduce the basic concepts and give an overview of some advanced features.
Machine & Deep Learning: We provide a fundamental introduction into machine and deep learning approaches as well as data processing techniques that support dataset preparation or model selection for training and inference. It covers the basic concepts for supervised and unsupervised learning such as classification, regression, and clustering to get a feeling which technique is appropriate for a particular problem. Additionally, we conduct several hands-on exercises with common frameworks such as scikit-learn and PyTorch on our recent HPC Cluster CLAIX. In these exercises, we demonstrate how to define models, construct dataset and training pipelines or utilize monitoring and visualization of the training results, e.g., with Tensorboard. For the deep learning exercises, we start by training on a single GPU first. If that is not enough, we also show how to scale up distributed training onto multiple compute nodes or GPUs.
Organization

There is no seminar fee.
Presentations will be given in English. Slides will be available during or after the event.
This is an in-person event and will be held on the RWTH IT Center premises (see below).
You can/must register per day.

Name: NHR4CES Community Workshop 2026 “From Raw Data to Real Insights: Synergizing Data Engineering and AI for HPC”
Date: May 11 -12, 2026
Format: online
More information & registration

Description
With the continuous expansion of High-Performance Computing (HPC) capabilities, researchers are facing an unprecedented abundance of research data. To effectively harness this potential, isolated approaches are no longer sufficient; instead, a synergy of robust data management and advanced analytics is required.
This workshop, organized by the CSG Data Engineering & AI, addresses the complete data lifecycle on HPC systems. We will explore how to bridge the gap between raw infrastructure and scientific discovery by integrating Research Data Management (RDM), Automated Data Engineering, and Artificial Intelligence. The session will cover strategies ranging from workflows for ensuring data quality and storage, to applying Machine Learning and Process Mining for deeper analysis. By focusing on these intersecting disciplines, we aim to demonstrate how researchers can achieve scalable, reproducible results that adhere to FAIR principles, ultimately transforming raw data into real, actionable insights.

Name: Introduction to Scientific Visualization with ParaView
Date: May 13, 2026
Format: online
More information & registration

Description

Short abstract:

Scientific Visualization allows researchers to gain visual insights into complex data, that would otherwise be hidden within numbers and models. This is especially true for data describing physical phenomena, from blood flow simulations to combustion processes. The de-facto standard tool for visualization in these domains is ParaView. It is an open-source, multi-platform scientific data analysis and visualization tool that enables analysis and visualization of extremely large datasets.
In this course, attendants will learn the basics of scientific visualization and how these can be applied in ParaView, including filtering, rendering, and animating complex data.
