Structure

WP1 objective is to set up an effective management framework for the EESI2 consortium to ensure progress of the project towards its planned objectives and respect of contractual commitments.

The specific objectives of WP1 are:

• To set-up the management infrastructure: management bodies, management procedures and tools, quality plan, remote collaboration tools, etc.
• To ensure strategic, financial and contractual management of the consortium, including maintenance of the Consortium Agreement
• To ensure the day-to-day operational project management.

This Work Package is divided into the following tasks:

• T1.1: Project Global Management;
• T1.2 : Project administrative management.

WP2 has different objectives:

• Investigate and describe state-of-the-art, trends, and future needs in HPC training and education.
• Establish and maintain a global network of expertise and funding bodies in the area of Exascale computing.
• Investigate and describe the establishment and landscape of co-design centers in the area of HPC and specifically Exascale computing. Monitor functioning of international existing centers.
• Act as a proactive European voice and representative into the International Exascale Software Community.
• Integrate within WP tasks, cartography update through continuous use of network.

 This Work Package is divided into the following tasks:

• T2.1 State of the art on funding agencies;
• T2.2 State of the art on education courses and training needs;
• T2.3 State of the art of worldwide Co-design centers;
• T2.4 Towards a public collaboration.

WP3 will work on extending, refining and producing applications roadmap. WP3 will pave the path by:

• Investigating on key application breakthroughs, quantifying their societal, environmental and economical impacts and performing a gap analysis between current situation and Exascale targets;
• Evaluating the R&D activity performed by scientific and industrial communities, especially in applications redesigning and development of multiscale/multiphysics frameworks;
• Fostering the structurating of scientific communities at the European level.
• Integrating within WP tasks, cartography update through continuous use of network

 This Work Package is divided into the following tasks:

• T3.1: WG Industrial and engineering applications;
• T3.2: WG Weather, Climatology and Earth Sciences;
• T3.3: WG Fundamental Sciences;
• T3.4: WG Life Science & Health;
• T3.5: WG Disruptive technologies;
• T3.6: Coordination.

The objective of the WP is to create and manage four working groups of experts on enabling technologies for Exascale development that are considered essential for Exascale software. For example, for a long time numerical analysis addressed solvers for stochastic PDE or complex equations. Discretization is a key issue in equation resolution. The level of parallelization is clearly “physically equation dependent”. Exascale solvers require at least 1 or 2 more levels of parallelization, even when Exascale systems will be used by weak scalability.

The topics of the working groups considered in this work package are:

• Numerical analysis, with aspects such as dense linear algebra, graph and hypergraph partitioning, sparse direct methods, Iterative methods for sparse matrices, Eigenvalue problems, model reduction, optimization, robust optimization, and Control of complex systems
• Scientific software engineering, software eco-system, and programmability
• Disruptive technologies
• Hardware and operating software vendors

 This Work Package is divided into the following tasks:

• T4.1 WG Numerical analysis;
• T4.2: WG Scientific software engineering, software eco-system and programmability;
• T4.3 : WG Disruptive technologies;
• T4.4 : WG Hardware and operating software vendors;
• T4.5: Coordination.

The objective of the WP is to create and manage five working groups of experts on cross cutting issues for Exascale development to push the Exascale software initiative with the objectives of:

• Define Data management and exploration specific issues roadmap
• Define actions and follow up of projects on uncertainties
• Identify power management impact on the system design and on programmability
• Define concrete actions to achieve the best coupling Architecture-Algorithm-Application
• Define concrete objectives in terms of fault tolerance at system and application level
• Survey new hardware and software technologies in order to monitor technologies that could influence the design of Exascale systems
• Integrate within WP tasks, cartography update through continuous use of network

 This Work Package is divided into the following tasks:

• T5.1: WG Data management and exploration;
• T5.2: WG Uncertainties;
• T5.3: WG Power & Performance;
• T5.4: WG Resilience;
• T5.5: WG Disruptive technologies;
• T5.6: Coordination.

One recommendation of EESI1 is the establishment of a European Exascale Software Centre to coordinate research, development, testing, and validation of HPC Exascale software ecosystem components and modules developed in National and EU projects. To investigate the feasibility and to prepare for the operation of such a centre, WP6 objective is to:

• Develop and document a methodology for estimating the level of maturity of Exascale software components
• Identify 3 software stack components from existing and near future European Exascale projects and apply the defined methodology
• Examine functionary of existing “equivalent» centres and propose to Europe structure adapted to Exascale software.

 This Work Package is divided into the following tasks:

• T6.1: Evaluation methodology set up;
• T6.2: Perform evaluation on 3 components.

EESI2 main objectives are to provide a vision and a roadmap to the community and R&D stakeholders. Overall synthesis will be provided on all WP activities with a particular focus on software key issues improvement (gap analysis), enabling technologies and applications, cross cutting issues advances and international aspects, leading to a global vision and perspective of Exascale software development, update world state of art and future.

These periodic recommendations should be synchronized as much as possible with EC R&D projects decision agenda.

WP8 will disseminate all inputs of the project to the community. It aims at:

• Design and execute a communication strategy;
• Organizing two internal workshops;
• Organizing a European Exascale conference.

 This Work Package is divided into the following tasks:

• T8.1: Organization of technical workshops;
• T8.2: Organization of European Exascale conference;
• T8.3 Information Dissemination;
• T8.4 EESI in Europe and world-wide.
