EIA-9975018Rauchwerger, LawrenceCISE Next Generation Software(NG)Texas Engineering Experimental StationSmartApps: Smart Applications for Heterogeneous ComputingThis proposal proposes to generate SMART APPLICATION code that uses information about its input data, operating system services and architecture capability, to adaptively reconfigure the application and the OS/hardware platform. To enable very aggressive optimizations, we propose to build a two-stage compiler which has a static and run-time component. The run-time component is extremely fast, works in parallel on the target machine and can read all relevant input data, and the operating system and architectural capabilities. Furthermore, to adapt the performance to variable program inputs during execution, we propose to use novel speculative run-time adaptive optimization techniques (for example, the PI's speculative parallelization and a feedback loop of performance evaluator, predictor and optimizer inputs. All this support will be enabled by a run-time library and the necessary compiler-embedded code in the executable. With this approach, the application can adapt itself and its environment to its needs by issuing appropriate commands. For instance, it is able to control data placement by the OS, control the I/O subsystem, modify coherence protocols and establish network connections. Moreover, smart applications are able to respond to the failures and large performance variations that distributed systems suffer.

EIA-9975018 Rauchwerger，LawrenceCISE下一代软件（NG）Texas Engineering Experimental Station智能应用程序：异构计算的智能应用程序该提案建议生成智能应用程序代码，该代码使用有关其输入数据、操作系统服务和体系结构能力的信息，以自适应地重新配置应用程序和OS/硬件平台。 为了使非常积极的优化，我们建议建立一个两阶段的编译器，它有一个静态和运行时组件。 运行时组件非常快，在目标机器上并行工作，可以读取所有相关的输入数据，以及操作系统和体系结构功能。 此外，在执行过程中，为了适应可变的程序输入的性能，我们建议使用新的投机运行时自适应优化技术（例如，PI的投机并行化和性能评估器，预测器和优化器输入的反馈回路。 所有这些支持都将通过运行时库和可执行文件中必要的编译器嵌入式代码来实现。 通过这种方法，应用程序可以通过发出适当的命令来调整自身及其环境以满足其需求。 例如，它能够通过操作系统控制数据放置，控制I/O子系统，修改一致性协议并建立网络连接。 此外，智能应用程序能够对分布式系统所遭受的故障和大的性能变化做出响应。
