Extensions Of Task-Based Runtime For High Performance Dense Linear Algebra Applications, Chongxiao Cao
Extensions Of Task-Based Runtime For High Performance Dense Linear Algebra Applications, Chongxiao Cao
Doctoral Dissertations
On the road to exascale computing, the gap between hardware peak performance and application performance is increasing as system scale, chip density and inherent complexity of modern supercomputers are expanding. Even if we put aside the difficulty to express algorithmic parallelism and to efficiently execute applications at large scale, other open questions remain. The ever-growing scale of modern supercomputers induces a fast decline of the Mean Time To Failure. A generic, low-overhead, resilient extension becomes a desired aptitude for any programming paradigm. This dissertation addresses these two critical issues, designing an efficient unified linear algebra development environment using a task-based …
