CRESTA: a software focussed approach to exascale co-design

The CRESTA project is one of three complementary exascale software projects funded by the European Commission. The three-year project is employing a novel approach to exascale system co-design which focuses on the use of a small, representative set of applications to inform and guide software and systemware developments. This methodology is designed to identify where problem areas exist in applications and to use that knowledge to consider different solutions to those problems which inform software and hardware advances. CRESTA uses a methodology of either incremental or disruptive advances to move towards solutions across the whole of the exascale software stack.
