Structure of the work plan

Graph showing the relation between work packages and list of work packages and tasks

The graph illustrates the spirit of creating a centre serving the community. The interaction of the three scientific/technical work packages which focus on the three ESiWACE themes is supported on the administrative level by WP5 and steered by WP1 to guarantee that the work is informed by and responds to community requirements.

WP1 Governance and engagement

Goal:

  • Better engaging the climate and weather modelling communities using Earth system models in the ESiWACE and ensure the ESiWACE serves the communities
  • Ensuring user representation in the governance of common software and in ESiWACE new developments
  • Ensuring consistency and exploitation of possible synergies with other relevant activities in which the community is engaged (infrastructure projects, FETs, environment projects…)
  • Enhancing community capacity in HPC: WP1 will foster efficient use of HPC through regular exchanges with the communities
  • Networking with industry and ETP4HPC: WP1 will network with ETP4HPC and relevant hardware and software industry
  • Strengthening strategy and business planning

Lead: Sylvie Joussaume CNRS-IPSL (lead) and Joachim Biercamp DKRZ (co-lead)

Duration: Months 1-48

Partners: CNRS-IPSL, DKRZ, ECMWF, MPI, CERFACS, BSC, SMHI, CMCC, Bull

Tasks' structure:

T1.1 Engagement and governance
T1.2 Enhancing community capacity in HPC
T1.3 Strategic interaction with HPC ecosystem and HPC industry
T1.4 Sustainability and business planning

WP2 Scalability

Goals:

  • Demonstrate how to build and productively operate global cloud resolving models
  • Improve efficiency and scalability of community models and tools and provide improved access to scientific and performance upgrades
  • Provide support and training for community I/O and coupling tools and establish convergence strategies for the future
  • In the exascale perspective, investigate scientific and technical options for efficiency upgrades and methodologies, in particular to reduce volume of future high-resolution modelling output

Lead: Peter Bauer ECMWF (lead) and Sophie Valcke CERFACS (co-lead)

Duration: Months 1-48

Partners: ECMWF, DKRZ, CNRS-IPSL, MPI, CERFACS, BSC, METO, SMHI, ICHEC, CMCC, Bull

Tasks' structure:

T2.1 Support, training and integration of state of-the-art community models and tools
T2.2 Global high-resolution model demonstrators
T2.3 Efficiency enhancement of models and tools
T2.4 Preparing for exascale

WP3 Usability

Goals:

  • Support scientific excellence through provision of effective HPC and big data infrastructures by allowing scientists to more easily design and carry out simulation campaigns that seamlessly exploit the existing multi-model framework, including the inherent value of model diversity
  • Considerably improve the ease-of-use of the software, computing and data-handling infrastructure for ESM scientists from the applications through the software stack to the hardware
  • Support the uptake of scheduling engines within the community through user-driven development, training and support services. This activity will absorb 40% of the effort in this work package, since it will provide a step change in the community's ability to cope with increasing suite complexity for both climate and weather applications in production and research modes. MetO, who have existing skills in Cylc and are supporting its adoption, will lead this task
  • Reduce the skills gaps at individual centres by sharing best practice through worked examples using use-cases derived from user-driven engagement, the need to prepare extreme scale demonstrators see WP2), and governance
  • Propose avenues for co-design of system software and architectures between industry and applications

Lead: Reinhard Budich, MPI (lead) and Kim Serradell, BSC, Mick Carter, MetO (co-leads)

Duration: Months 1-48

Partners: MPI, DKRZ, ECMWF, BSC, METO, UREAD, CMCC, ALLINEA

Tasks' structure:

T3.1 ESM end-to-end workflows Recommendations
T3.2 ESM system software stack recommendations
T3.3 ESM scheduling
T3.4 Co-Design for Usability

WP4 Exploitability

Goals:

  • Understanding the business of storing and exploiting high volume Earth system data by developing a model which can be used to both understand the cost and performance of a range of storage strategies in weather and climate HPC workflows (and compare those with typical commercial strategies)
  • Developing a new disk storage layout for Earth system data to overcome the performance limitations of existing fixed on-disk formats and APIs by providing a novel data-specific layout interface. The new interface will be capable of supporting both interoperability between higher-level file formats and of customisation to local heterogeneous disk storage environments. It will be deployed in test mode to support the demonstrator activity
  • Developing new tape access strategies and software customised for Earth system data by first modelling and simulating possible strategies, and then developing a new software library which provides both higher bandwidth to tape storage and increased storage redundancy

Lead: Bryan Lawrence, STFC (lead) and Thomas Ludwig, DKRZ (co-lead)

Duration: Months 1-48

Partners: STFC, DKRZ, ECMWF, CMCC, SEAGATE

Tasks' structure:

T4.1 The business of storing and exploiting high volume climate data
T4.2 New storage layout for Earth system data
T4.3 New methods of exploiting tape

WP5 Management and Dissemination

Goal: ensure effective and smooth high-quality implementation of the project and delivery of innovation actions, and impacts

Lead: Joachim Biercamp, DKRZ (lead), Peter Bauer, ECMWF (co-lead)

Duration: Months 1-48

Partners: DKRZ, ECMWF, CNRS-IPSL, MPI, CERFACS, BSC

Tasks' structure:

T5.1 Coordination and management
T5.2 Risk management
T5.3 Innovation and IPR management, exploitation of results
T5.4 Dissemination
