Towards a codelet-based runtime for exascale computing
Christopher Lauderdale, Rishi Khan · 2012
Computing systems have reached the performance limits attainable by increasing clock rates and complexity, and are now using increased thread-level parallelism and heterogeneity instead. Existing software typically deals poorly with large-scale or heterogeneous computer systems, relying on multiple poorly interacting or special-purpose software interfaces to approach scaling/heterogeneity; attempting to use these approaches on future computers (especially at exascale) will only make matters worse.
