SEA Projects Selected for Funding by EuroHPC JU

The three members of the new SEA projects family (DEEP-SEA, IO-SEA, and RED-SEA) have been selected for funding in the first research and innovation call for proposals issued in 2019 by the EuroHPC Joint Undertaking (JU). The SEA projects complement each other and together address some of the most critical aspects concerning the operation and use of an exascale supercomputer: programming environment, data management, and interconnects. The projects will start in early 2021 and run for a period of four years.

The goal of DEEP-SEA (“DEEP – Software for Exascale Architectures”) is to adapt all levels of the software stack to efficiently exploit highly heterogeneous compute and memory configurations, and to allow code optimisation across existing and future architectures and systems. The software stack will enable dynamic resource allocation, application malleability, and programming composability, and include tools to map applications to the Modular Supercomputing Architecture.

IO-SEA (“Input/Output Software for Exascale Architectures”) aims to provide a novel data management and storage platform for exascale computing based on hierarchical storage management and the on-demand provisioning of storage services. Efficient management of storage tiers is achieved by removing unnecessary data movements and considering critical aspects of intelligent placement for very large volumes of data.

RED-SEA (“Network Solutions for Exascale Architectures”) will pave the way for the next generation of European interconnects. In particular, it will develop the next generation of the Bull eXascale Interconnect, scalable to hundreds of thousands of nodes. New features and efficient network resource management covering congestion resiliency, virtualization, adaptive routing, and collective operations will be implemented.

The SEA projects are driven by a collaborative co-design approach with a selected set of high-impact applications. These representative applications help to formulate requirements that are addressed by software and hardware developers, and are also employed to evaluate the project’s results and demonstrate their benefits for users of European computing centres.

JSC participates in all three SEA projects. In addition to leading the DEEP-SEA project and the definition of its software stack, JSC contributes the performance analysis tools Score-P and Scalasca, the monitoring tool LLview, the I/O library SIONlib, and the benchmarking tools Linktest and JUBE. JSC also provides application use cases in the areas of Earth system modelling and quantum chromodynamics. Furthermore, JSC leads the co-design activities in DEEP-SEA and IO-SEA.
