The advent of multicore processors has introduced new opportunities for achievingincreased software performance, reliability, security, and availability. However,powerful dynamic execution monitoring capabilities are required to realize theseopportunities. This project addresses the challenges of developing a DynamicBinary Translation based monitoring framework for parallel applications running onmulticore systems. The programmability of the framework will enable realization of benefits in achieving enhanced performance, reliability, security, and availability. Some of the instrumentation code required in context of parallel applications must be executed by a core in response to events that involve other cores. In particular, events relevant to many performance, reliability, and security related tasks correspond to the manifestation of interprocessor data dependences due to updates of shared memory locations by multiple cores. Based upon this observation programmable architectural mechanisms will be provided that not only enable the detection of interprocessor dependence events but also enable the triggering of the execution of application specific monitoring code. This project will then employ these mechanisms for improving performance via speculative parallelism, enabling debugging via anovel strategy of execution suppression, improving reliability via an approach thatallows applications to automatically recover from failures, providing security viadynamic detection of mutating viruses, and software availability via dynamic updates.

多核处理器的出现为实现软件性能，可靠性，安全性和可用性提供了新的机会。但是，需要强大的动态执行监控功能才能实现这些企业。该项目应对开发基于动态翻译的监视框架的挑战，该框架针对运行Onmulticore Systems的并行应用程序。该框架的可编程性将使您能够实现增强性能，可靠性，安全性和可用性的收益。并行应用程序中所需的某些仪器代码必须由核心对涉及其他内核的事件执行。特别是，由于多个内核对共享存储器位置的更新，与许多性能，可靠性和相关任务相关的事件对应于处理器数据依赖的表现。基于此观察可编程的架构机制，将提供不仅可以检测到处理器依赖事件的检测，而且还可以触发执行应用程序特定监控代码的执行。然后，该项目将采用这些机制通过投机性并行性来提高性能，从而通过执行抑制的主管策略进行调试，通过方法提高可靠性，以使应用程序从失败中自动恢复自动恢复，从而通过动态更新提供了突变病毒的安全性检测以及软件可用性。
