摘要

ANTAREX项目旨在通过领域特定语言(DSL)表达应用程序的自适应性,并为绿色和异构高性能计算(HPC)系统进行运行时管理和自动调整应用程序,最高可达Exascale。DSL方法允许定义能效、性能和适应性策略,以及通过应用程序自动调优、资源和电源管理在运行时实施这些策略。通过从一个项目应用程序用例中提取的一个小应用程序,我们展示了通过DSL支持的方式对应用程序精度调优的一些初步探索。

The ANTAREX approach to autotuning and adaptivity for energy efficient HPC systems
The ANTAREX project aims at expressing the application self-adaptivity through a Domain Specific Language (DSL) and to runtime manage and autotune applications for green and heterogeneous High Performance Computing (HPC) systems up to Exascale. The DSL approach allows the definition of energy-efficiency, performance, and adaptivity strategies as well as their enforcement at runtime through application autotuning and resource and power management. We show through a mini-app extracted from one of the project application use cases some initial exploration of application precision tuning by means enabled by the DSL.
