The EU-H2020 ESCAPE (www.hpc-escape.eu) project brings together numerical weather prediction (NWP), climate and high-performance computing (HPC) communities to develop world-class, extreme-scale computing capabilities for European operational NWP and future climate models. One of the challenges is to execute complex state-of-the-art models of the atmosphere within tight production schedules.

The workshop sessions were organized according to the following topics (with oral presentations, including keynote speakers):

• Introduction to the ESCAPE project
• Weather & Climate Dwarfs – aspects and fundamental algorithmic building blocks underlying weather and climate services;
• Diagnostic methods and tools, co-design and algorithms development for use in extreme-scale, HPC applications, minimizing time- and cost-to-solution;
• Session for relevant EU projects / Consortia involving HPC for weather, climate, ocean/sea, Earth System Modelling communities
• Panel discussions on key issues from the workshop

The programme for the workshop was as follows - the workshop presentations can be downloaded from the programme, abstracts are available in the Workshop Booklet and a summary of the workshop can be found in the ESCAPE deliverable D5.9:
