ABSTRACT SGER: Compiler-driven Adaptive ExecutionThe goal of this project is to study dynamically adapting compiler-translated MPI applications in a distributed system. In previous work we have created a system for dynamic adaptation and tuning of computational applications. The current study includes, deploying a translator that converts OpenMP parallel applications directly into MPImessage passing programs, and investigating new methods to enable dynamic, adaptive optimization and tuning in diverse architectures. The architecture space explored includeshomogeneous multiprocessors, clusters, and heterogeneous systems, such as computational Grids.The project includes: selecting compilation parameters in the OpenMP-to-MPI translator,developed previously, that are amenable to dynamic adaptation, and turn these parameters into compiler options; adaptively optimize these parameters with a perfomance tuning system; and study the potential for dynamic adaptation through analytic and measured evaluation of the overheads and gains of performing adaptation during the program execution. An important part of the evaluation will be to test the methods pursued on applications that exhibit potential for such adaptation. As part of the project a workshop on Compiler-driven Adaptive Execution Systems will be organized, to convene researchers active in the field of dynamic and adaptive Compilation, and address a broad range of topics from success stories of compiler-driven adaptive execution to the potential of such methods to the enabling technology.

SGER：编译器驱动的自适应执行本项目的目标是研究在分布式系统中动态适应编译器翻译的MPI应用程序。在以前的工作中，我们已经创建了一个动态适应和调整计算应用程序的系统。目前的研究包括部署一个转换器，将OpenMP并行应用程序直接转换为MPImessage传递程序，并研究在不同架构中实现动态、自适应优化和调优的新方法。所探索的架构空间包括同构多处理器、集群和异构系统，如计算网格。该项目包括：在先前开发的OpenMP-to-MPI转换器中选择可动态适应的编译参数，并将这些参数转换为编译器选项；利用性能调整系统对这些参数进行自适应优化；并通过分析和测量评估在项目执行过程中执行适应的开销和收益来研究动态适应的潜力。评价的一个重要部分将是检验对显示出这种适应潜力的应用所采取的方法。作为项目的一部分，将组织一个关于编译器驱动的自适应执行系统的研讨会，以召集活跃在动态和自适应编译领域的研究人员，并讨论从编译器驱动的自适应执行的成功故事到这些方法的潜力再到使能技术的广泛主题。
