dc.description.abstractToday’s most powerful supercomputers achieve their performance through heterogeneous system architectures that integrate CPUs with accelerators, especially GPUs, and advanced multi-level memory systems. This hardware diversity challenges application developers to adapt legacy code, requiring significant efforts in code evolution and optimisation. The European DEEP-SEA project has developed an integrated software stack for heterogeneous HPC systems, including kernel modules, libraries, management systems and programming abstractions. It supports heterogeneous hardware configurations including modular supercomputers, enabling optimal resource allocation, application of malleability and programming model composability. Enhanced tools and data placement policies improved performance on DRAM and fast memory. Results were made publicly available, ensuring sustainability through integration with upstream open source projects and extension of HPC standards. This paper summarises the DEEP-SEA project’s contributions to a wide variety of software packages and developments.en
