On January 28, the EUPEX project will organise a workshop titled “Preparing Applications and European Users to Efficiently Exploit Future ARM-based Exascale Machines” at HiPEAC 2026 in Krakow. EUPEX is a European project bringing together academic and industrial partners to co-design an exascale-ready pilot system based on European technologies. The pilot aims to prepare users and the HPC community to effectively use ARM-based architectures and future European exascale processors like SiPearl’s chips. HiPEAC was chosen for this workshop because it is one of Europe’s leading networks and annual conferences for high-performance and embedded computing, fostering collaboration and innovation across academia and industry. The workshop session will focus on ARM-based architectures and offer practical insight into optimising applications and improving energy efficiency on these cutting-edge systems. Workshop focus and objectives Attendees will explore strategies for efficient application performance on future ARM-based exascale machines, including porting applications to ARM architectures, energy profiling, and optimisation techniques. The workshop will also provide a comprehensive overview of the European HPC ecosystem, helping participants understand the broader context in which the …
