In this deck from the Blue Waters Summit, Thomas Schulthess from CSCS presents: Reflecting on the Goal and Baseline of Exascale Computing.
"Application performance is given much emphasis in discussions of exascale computing. A 50-fold increase in sustained performance over today's applications running on multi-petaflops supercomputing platforms should be the expected target for exascale systems deployed early next decade. In the present talk, we will reflect on what this means in practice and how much these exascale systems will advance the state of the art. Experience with today's platforms show that there can be an order of magnitude difference in performance within a given class of numerical methods, depending only on choice of architecture and implementation. This bears the questions on what our baseline is, over which the performance improvements of exascale systems will be measured. Furthermore, how close will these exascale systems bring us to deliver on scientific goals, such as convection resolving global climate simulations or throughput oriented computations for meteorology?"
