|ESCAPE stands for Energy-efficient Scalable Algorithms for Weather Prediction at Exascale.
The project will develop world-class, extreme-scale computing
capabilities for European operational numerical weather prediction (NWP)
and future climate models. The biggest challenge for state-of-the-art
NWP arises from the need to simulate complex physical phenomena within
tight production schedules. Existing extreme-scale application software
of weather and climate services is ill-equipped to adapt to the rapidly
evolving hardware. This is exacerbated by other drivers for hardware
development, with processor arrangements not necessarily optimal for
weather and climate simulations. ESCAPE will redress this imbalance
through innovation actions that fundamentally reform Earth system
modelling. ESCAPE addresses the ETP4HPC
Strategic Research Agenda 'Energy and resiliency' priority topic,
developing a holistic understanding of energy-efficiency for
extreme-scale applications using heterogeneous architectures,
accelerators and special compute units. The three key reasons why this
project will provide the necessary means to take a huge step forward in
weather and climate modelling as well as interdisciplinary research on
energy-efficient high-performance computing are:
- Defining and encapsulating the fundamental algorithmic building
blocks ('Weather & Climate Dwarfs') underlying weather and climate
services. This is the prerequisite for any subsequent co-design,
optimization, and adaptation efforts.
- Combining ground-breaking frontier research on algorithm development
for use in extreme-scale, high-performance computing applications,
minimizing time- and cost-to-solution.
- Synthesizing the complementary skills of all project partners. ECMWF
and leading European regional forecasting consortia are teaming up with
excellent university research and experienced high-performance
computing centres, two world-leading hardware companies, and one
European start-up SME, providing entirely new knowledge and technology
to the field.
ECMWF’s partners in the project are Danmarks Meteorologiske Institut;
Deutscher Wetterdienst; l'Institut Royal Météorologique de Belgique;
Météo-France; MeteoSchweiz; Instytut Chemii Bioorganicznej Polskiej
Akademii Nauk; Loughborough University; National University of Ireland,
Galway; Bull SAS; NVIDIA Corporation; and Optalysys Ltd.
ESCAPE is an integral part of the ECMWF Scalability Programme and
supports in particular the Polymitos and PantaRhei projects in view of
the future dynamical core developments at ECMWF. ESCAPE will also
produce benefit for ESiWACE,
the Centre of Excellence in Simulation of Weather and Climate in
Europe, as code developments will be made available to the wider
community via OpenIFS.
ESCAPE is funded by the European Commission under the Future and Emerging Technologies - High-Performance Computing call for research and innovation actions, grant agreement 671627.
