ECMWF involvement in the EU CRESTA project

IFS is one of the six co-design applications that are being investigated for running in the
future at the Exascale.

Some areas of investigation in CRESTA include:

  • overlapping computation and communication by using Fortran2008 coarrays in the Legendre transforms, Fourier Transforms and semi-Lagrangian scheme.
  • running the radiation scheme in parallel with the rest of the model.
  • development of new solvers using unstructured meshes, suitable for extreme scaling of IFS and a potential replacement for the spectral method.
  • preliminary investigation into use of accelerator technology (MIC, GPU).

This project has received funding from the European Union’s Framework Programme under grant agreement number 287703.

 

CRESTA brought together four of Europe’s leading supercomputing centres, with one of the world’s major equipment vendors, two of Europe’s leading programming tools providers and six application owners (including ECMWF/IFS model) to explore how the Exascale challenge can be met. The CRESTA project finished at the end of 2014.

The main areas of research that ECMWF pursued in the CRESTA project included:

  • overlapping computation and communication by using Fortran2008 coarrays in the Legendre transforms, Fourier Transforms and semi-Lagrangian scheme.
  • running the IFS radiation scheme in parallel with the rest of the model.
  • initial development of the Atlas library to support new solvers using unstructured meshes, suitable for extreme scaling of IFS and a potential replacement for the spectral method.
  • preliminary investigation into use of accelerator technology (MIC, GPU).
