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提高软件性能、可靠性、安全性和可用性带来了新的机遇。然而，强大的动态执行监控功能需要实现这些机会。该项目解决了为运行在多核系统上的并行应用程序开发基于动态二进制翻译的监控框架的挑战。该框架的可编程性将有助于实现增强的性能、可靠性、安全性和可用性。在并行应用的上下文中所需的一些插装代码必须由核执行以响应涉及其他核的事件。特别地，与许多性能、可靠性和安全性相关任务相关的事件对应于由于多个核对共享存储器位置的更新而引起的处理器间数据依赖性的表现。基于这种观察，将提供可编程架构机制，其不仅能够检测处理器间依赖事件，而且能够触发应用程序特定监视代码的执行。本项目将采用这些机制通过推测并行来提高性能，通过执行抑制的新策略来实现调试，通过允许应用程序自动从故障中恢复的方法来提高可靠性，通过对变异病毒的自动检测来提供安全性，以及通过动态更新来提供软件可用性。
