Developing a programming environment for European Exascale systems

Following the successful completion of DEEP-EST and the launch of the prototype at the Jülich Supercomputing Centre, the DEEP projects face a new challenge: how to design programming environments that can support future Exascale systems with a wide variety of different workloads.

Enter DEEP-SEA (DEEP – Software for Exascale Architectures). DEEP-SEA started in April 2021 with a duration of 3 years. The project provides the programming environment for future European Exascale systems, adapting all levels of the software stack to support highly heterogeneous compute and memory configurations. It will also enable code optimisation across existing and future architectures and systems. The software stack includes low-level drivers, computation and communication libraries, resource management and programming abstractions with associated runtime systems and tools.


DEEP stands for Dynamical Exascale Entry Platform. Since 2011, the DEEP series of projects (DEEP, DEEP-ER, DEEP-EST and now DEEP-SEA) has pioneered an innovative concept known as the Modular Supercomputer Architecture (MSA). This novel HPC architecture paves the way for the next milestone in supercomputing: Exascale systems with the power to perform 1018 Floating Point Operations per second.
