11. OpenPHIGS: How an enthusiastic game developer accidentially helped to save LEP data

Dr Ulrich Schwickerath (CERN)

Event displays are an excellent tool to visualise HEP events, for physicist but also for outreach. In the old days,these 3d visualisation tools were a challenge, and thus some experiments decided to use a commercial closed source back-end solution. This talk tells the story of how a little open source project of an enthusiastic game developer
helped to resurrect these useful tools for two of...

12. A lib to Integrate OpenAPI Generator into CERN React Apps

At CERN’s Business Computing Group, we're developing a large-scale React UI for one of CERN’s biggest business applications.
Integrating OpenAPI Generator into React brings clear benefits, but the process isn’t always straightforward.
With no official guidelines or common patterns, developers often create their own strategies to integrate OpenApi Generator into React apps, which can lead to...

CERNBox is an open-source cloud storage platform designed to serve the entire CERN community. Since its launch in 2014, the service has grown to manage more than four billion files and support over 8,000 daily users. Its open-source nature has enabled adoption by partner institutions such as the University of Paris-Saclay and the University of Vienna. Recent developments improved CERNBox’s...

10. Adaptyst: modular architecture-agnostic performance analysis tool

Adaptyst is a novel open-source performance analysis project started at CERN as part of the SYCLOPS EU-funded project, currently in an early development phase with the ambitious roadmap for the next few years. The ultimate goal of the tool is using both static and dynamic methods to suggest the most optimal compute solution performance-wise (latency, throughput, energy efficiency, budget cost...
