<\/h2>\nTopic: I\/O and Data Handling for HPC and ML Codes (on CLAIX)<\/h1>\n<\/h2>\nDescription<\/h2>\n
<\/h2>\nDescription<\/h2>\n
The 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”.<\/p>\n
Presentations (open to everyone)<\/h3>\n
Presentations (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. The sessions on “Code and Tuning Activities” (see agenda below) follow the principle of bring-your-own (BYO) code<\/strong>. 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. To make good use of the time with our HPC\/ML experts, it is necessary (until the workshop date) that…<\/p>\n Date: December 2nd (and December 3rd), 2025 Registration link (via our NHR4CES website): https:\/\/eveeno.com\/aixcelerate_2025<\/a><\/p>\n During the registration, please specify whether you want to participate in-person or online.\u00a0Please also withdraw your registration<\/strong> in the registration system using the link that you got in your confirmation e-mail (or let us know) if you cannot attend anymore.

\nTalks are offered in a hybrid<\/strong> form: The presenters will do their talks in-person<\/strong> 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<\/strong> form. Hence, participants can also attend remotely. Participants need to choose their setup (on-premise or online) during the registration process.<\/p>\nCode & Tuning Activities (limited seats)<\/h3>\n
\nSince participants will work together with our experts, this part can only be attended in-person <\/strong>and on-premise<\/strong>. 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.<\/p>\nRequirements for “BYO Code”<\/h4>\n
