The society increasingly relies on sophisticated computer systems for numerous applications from search engines (e.g. google.com, yahoo.com) to geographical information systems (e.g. maps.google.com), eCommerce systems and handheld music and video players. Such systems have stringent performance requirements either because of the volume of data, the number of simultaneous users or real-time  constraints. Yet, achieving the desired level of performance assumes  proper interaction between several software programs, the operating system and often several networked computers.The objective of the proposed research program is to develop tools and techniques for highly accurate and low disturbance system level performance analysis of uniprocessor, multiprocessor and distributed systems. This is particularly challenging with newer computer systems using multiple processors, with dynamically changing clock frequency, multi-threaded preemptive operating systems (e.g. Linux with preemption) and multiple virtual machines running over an hypervisor (e.g. Xen).The proposed system uses source code instrumentation at the operating system and user level in order to gather a detailed and precise trace of significant events. The instrumentation needs to have a minimal impact on both overall performance and on events ordering (scheduling). Special purpose analysis and viewing modules will be developed to study the performance of different subsystems (memory, disk I/O, networking...). Collaboration is already under way with industrial partners faced with very demanding applications. These industrial partners will provide both real life sample applications needing sophisticated performance analysis tools, and feedback on the efficiency, accuracy and applicability of the proposed algorithms, techiques and tools.

从搜索引擎(例如google.com、yahoo.com)到地理信息系统(例如maps.google.com)、电子商务系统以及手持音乐和视频播放器，社会日益依赖复杂的计算机系统来进行大量应用。这类系统要么是因为数据量、并发用户数，要么是因为实时性的限制，对性能有严格的要求。然而，要达到期望的性能水平，需要几个软件程序、操作系统和通常几个联网计算机之间的适当交互。所提出的研究计划的目标是开发工具和技术，用于单处理器、多处理器和分布式系统的高精度和低干扰的系统级性能分析。这对于使用多处理器、动态改变时钟频率、多线程抢占式操作系统(例如带抢占功能的Linux)和在管理程序(例如Xen)上运行的多个虚拟机的较新的计算机系统来说尤其具有挑战性。检测需要对整体性能和事件排序(调度)产生最小的影响。将开发专门用途的分析和查看模块，以研究不同子系统(内存、磁盘I/O、联网……)的性能。与面临非常苛刻应用的行业合作伙伴的协作已经在进行中。这些行业合作伙伴将提供需要复杂性能分析工具的真实生活样本应用程序，并就建议的算法、技术和工具的效率、准确性和适用性提供反馈。
