CSCS has published several videos from PAC15 conference in Switzerland. Including" Algorithmic Adaptations to Extreme Scale", from David Keyes, King Abdullah University , Saudi Arabia. Keyes explains algorithmic adaptations are required to use anticipated exascale hardware near its potential, since the code base has been engineered to squeeze out flops. Instead, algorithms must now squeeze out synchronizations, memory, and transfers, while extra flops on locally cacheable data represent small costs in time and energy.
