This project systematically addresses the enormous complexity of mapping applications to current and future parallel platforms - both scalable parallel architectures consisting of tens of thousands of processors and distributed systems comprised of collections of these and other resources. By integrating the system layers - domain-specific environment, application program, compiler, run-time environment, performance models and simulation, and workflow manager -- and through a systematic strategy for application mapping, the project will exploit the vast machine resources available in such parallel platforms to dramatically increase the productivity of application programmers.The key contribution of the project will be a systematic solution for performance optimization and adaptive application mapping -- a large step towards automating a process that is currently performed in an ad hoc way by programmers and compilers -- so that it is feasible to obtain scalable performance on parallel and distributed systems consisting of tens of thousands of processing nodes. The application components will be viewed as dynamically adaptive algorithms for which there exist a set of variants and parameters that can be chosen to develop an optimized implementation. Knowledge representation and machine learning techniques utilize this domain knowledge and past experience to navigate the search space efficiently.

该项目系统地解决了将应用程序映射到当前和未来并行平台的巨大复杂性——这两种平台都是由数万个处理器组成的可扩展并行架构，以及由这些资源和其他资源的集合组成的分布式系统。通过集成系统层——特定领域的环境、应用程序、编译器、运行时环境、性能模型和模拟以及工作流管理器——并通过应用程序映射的系统策略，该项目将利用可利用的大量机器资源。这种并行平台可以显着提高应用程序程序员的生产力。该项目的主要贡献将是性能优化和自适应应用程序映射的系统解决方案——朝着自动化当前由程序员以临时方式执行的流程迈出了一大步和编译器——这样就可以获得可扩展的性能由数万个处理节点组成的并行分布式系统。应用程序组件将被视为动态自适应算法，存在一组可以选择来开发优化实现的变体和参数。 知识表示和机器学习技术利用该领域知识和过去的经验来有效地导航搜索空间。
