© 2011 Martin Beniston Possible 1-day ICES Workshop in Geneva: April 15, 2011 n PART 1: n Overview papers to give a flavor of the "big topics" and emerging domains requiring HPC++, e.g., u Cosmology and solar science u Climate Sciences u Tectonics u Space-borne observation technologies n PART 2: n Bridging the disciplines: integrating complex, multi- dimensional science u From « hard science » to decision making, what are the options to convince the stakeholders, policy-makers, the general public, etc., that science is providing sound results?
