Technical workshop 2025 and hackathon
The 2025 edition of the ECLAT Technical Workshop and Hackathon brings together researchers, engineers, and partners to address the challenges of next-generation radio astronomy pipelines. Over five days, participants will discuss recent advances—from rapid prototyping and performance analysis to energy-constrained execution and data standardisation—while collaborating intensively during the hackathon. This event aims to strengthen collaborations and define the roadmap that will guide the development of tools and methodologies for the SKAO and future large-scale infrastructures.
