SUMMARY:aiXcelerate 2025
DESCRIPTION:in cooperation with \n\n\n\n\n\n\n\n\n\n  \n\nTopic: I/O and Data Handling for HPC and ML Codes (on CLAIX)\n\nDescription\nThe annual event aiXcelerate at RWTH Aachen University (NHR4CES@RWTH) is a tuning workshop for users of HPC systems. It comprises lectures that are open to everyone\, and hands-on parts where (invited) groups apply the learned concepts to their own (!) codes. This year\, aiXcelerate covers the topic “I/O and Data Handling for HPC and ML Codes” and focuses on using the RWTH’s HPC cluster “CLAIX”. \nPresentations (open to everyone)\nPresentations (see agenda below) give an introduction on I/O topics for HPC and ML codes. They cover\, e.g.\, an overview of available I/O solutions on CLAIX\, how they are best mapped to the I/O behavior of own codes\, and further tips and tricks.\nTalks are offered in a hybrid form: The presenters will do their talks in-person on the premises of the IT Center at RWTH Aachen University. Thus\, participants are very welcome to attend the presentations in-person\, too. Additionally\, presentations will be streamed live in online form. Hence\, participants can also attend remotely. Participants need to choose their setup (on-premise or online) during the registration process. \nCode & Tuning Activities (limited seats)\nThe sessions on “Code and Tuning Activities” (see agenda below) follow the principle of bring-your-own (BYO) code. They target at users with their own HPC or ML codes running on CLAIX and that (might) have (performance) issues with I/O and data handling. Participants of these sessions will closely work together with and get support by our HPC/ML experts to\, e.g.\, analyze the I/O performance of their codes and to tune the I/O and data handling of their codes.\nSince participants will work together with our experts\, this part can only be attended in-person and on-premise. We invite HPC and ML users with suitable compute time projects on CLAIX. Nevertheless\, other interested people are also welcome to register for this part of the workshop. However\, since seats are limited\, we reserve the right to only accept certain projects/ users for this workshop part. \nRequirements for “BYO Code”\nTo make good use of the time with our HPC/ML experts\, it is necessary (until the workshop date) that… \n\n … the brought code is already running on CLAIX (software & hardware environment).\n… a (test) dataset is available that (a) runs on few hardware ressources (e.g. CPUs or GPUs) for a short time (e.g.\, few minutes) and (b) still captures the I/O performance profile of a regular dataset by triggering the same production parts of the application.\n… all needed data is already transferred to one of the CLAIX’ file systems (HOME\, WORK\, HPCWORK).\n… at least one developer of the targeted application registered. Several people using the same application is also possible (please register separately).\n\nOrganization\n\nThere is no workshop fee.\nPresentations will be given in English. Slides will be available during or after the event (see “Course Material” below).\nPresentations are presented in hybrid form (see above). Please choose your setup during the registration process.\nCode activities are in-person on-premise only.\nPresentations and code activities focus on using the RWTH’s HPC cluster “CLAIX”.\n\nDate & Venue\nDate: December 2nd (and December 3rd)\, 2025\nVenue: IT Center of RWTH Aachen University\, Kopernikusstr. 6\, 52074 Aachen\, seminar rooms 3 + 4 (or online via Zoom/Webex) \nRegistration\nRegistration link (via our NHR4CES website): https://eveeno.com/aixcelerate_2025 \nDuring the registration\, please specify whether you want to participate in-person or online. Please also withdraw your registration in the registration system using the link that you got in your confirmation e-mail (or let us know) if you cannot attend anymore. That will help us a lot in preparing the event (seats\, catering and so on). Thanks! (Here are further instructions how to change or cancel your registration.) \nRegistration closing date: November 24th\, 2025\n \nAgenda\nAgenda is subject to slight changes. \nDay 1: Tuesday\, December 2nd\, 2025\n\n\n\nTime\nTopic\nSpeaker\n\n\n9:00 – 9:05\nWelcome\nSandra Wienke (RWTH)\n\n\n9:05 – 10:00\nDoes I/O Matter to Me?\nPhilipp Martin (RWTH)\n\n\n10:00 – 10:30\nStorage and I/O Technologies on CLAIX\nPhilipp Martin (RWTH)\n\n\n10:30 – 11:00\nCoffee Break\n\n\n11:00 – 12:00\nTips & Tricks & Tools with respect to I/O\nPhilipp Martin (RWTH)\n\n\n12:00 – 12:30\nFrom Thousands of Small Files to Few Very Big Files\nJannis Klinkenberg (RWTH)\n\n\nCode Activities (on-premise only)\n\n\n12:30 – 13:30\nLunch Break\n\n\n13:30 – 15:00\nCode Activities (BYO Code: Tuning with Experts)\n\n\n15:00 – 15:30\nCoffee Break\n\n\n15:30 – 17:30\nCode Activities (BYO Code: Tuning with Experts)\n\n\n\n

SUMMARY:CAESAR Community Workshop
DESCRIPTION:Name: CAESAR Community Workshop\n \nType of event: Workshop\n \nDate: December 5\, 2025\n \nTime: 9am to 2pm (CET) \nLocation: Online\n \nTarget group: Researchers who work with research software (as users or developers) \nRegistration: Please register by filling out the registration form before November 26th \n\n  \nBeschreibung \nCAESAR (Collaborative and Efficient Scientific Software Support Architecture) is an open\, discipline-independent initiative designed to enhance how research software is supported\, maintained\, and developed. The project seeks to automate and streamline support workflows\, mainly on GitHub\, addressing challenges such as issue reproducibility\, dependency management\, and transparent collaboration between users and developers. \nThis half-day workshop will introduce CAESAR’s concept and objectives\, showcase early demonstrations of the envisioned infrastructure\, and invite your input. Through breakout sessions\, lightning talks\, and interactive polls\, participants will help shape the system’s design and ensure it meets the real needs of the research software community. \nWorkshop highlights: \n\nIntroduction to the CAESAR concept and objectives\nDemonstration of early prototypes using pyGIMLi and envisioned workflows\nInteractive breakout discussions and feedback\nLightning talks on how scientific open-source software support is currently developed and maintained across projects\nNetworking opportunity for researchers and developers across disciplines\n\nYour participation and insights will play a key role in guiding CAESAR’s development toward a more efficient and sustainable research software support ecosystem. \nIf you are unable to attend but interested in the project\, we would still appreciate it if you could fill out the form and stay in touch to follow the project’s progress.

SUMMARY:[:en]NHR4CES - Numerical Methods for Combustion[:]
DESCRIPTION:Name: Numerical Methods for Combustion \nDate: December 5\, 2025\, 2pm – 6pm; \nFormat: online \nMore Information & Register \n  \n\n  \nDescription\n\n\nShort abstract:\nIn 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. \nThis 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. \nInformation about SDL Energy Conversion
