Date: January 30th - February 1st, 2013 in Toulouse (France)

One of the most pressing challenges our climate community has to face is to prepare its numerical models for the many-core new supercomputers which will deliver multi-petaflop and exaflop performance during the second half of the present decade.

As a  follow up of the  first IS-ENES Workshop on "Dynamical Cores", held in Lecce (Italy) in December 2011 (LINK), the 2nd workshop aims to exchange information on the status of:

  • European and International Earth System Models, reviewing their computational performance
  • The latest EU Exascale projects
  • Results from collaboration with the EU HPC facility PRACE and from large numerical climate experiments on PRACE
  • Issues related to ESM environments for HPC computing infrastructure,
  • Developments of new dynamical cores for climate and closely related high-performance computing issues, with emphasis on European projects and international state of the art.

The workshop is devoted to organize sharing of experience on these topics, listing the critical issues, to possibly reaching a general agreement of future strategies, and to leveraging international collaborations aiming at solving some common issues.
