EIA9807619 John K. Flanagan Brigham Young University Experimental Systems: A National Trace Collection and Distribution Resource. Trace-driven simulation is an important technique for research in computer architecture and compiler design. A trace-driven simulation uses actual execution traces as input to a compuer system simulator that can estimate resource usage or execution time. If both the system model and the input trace data represent the system under test, trace-driven simulation can be very accurate. This project collects and distributes accurate and representative trace data from a variety of computer systems running various operating systems and application workloads. Trace data is collected using commercial logic analyzers and a previously developed hardware monitor, which has successfully collected traces with billions of addresses from a variety of machines. Once collected, traces are managed and stored using large disk arrays and automated tapes, and are made available to users through the World-Wide Web, on tape, and on CD-ROM.

EIA9807619 John K.弗拉纳根杨百翰大学 实验系统：国家痕量收集和分配资源。 轨迹驱动仿真是计算机研究的一项重要技术 体系结构和编译器设计。 跟踪驱动的模拟使用实际执行跟踪作为计算机系统模拟器的输入，该模拟器可以估计资源使用或执行时间。 如果系统模型和输入跟踪数据都代表被测系统，则跟踪驱动的模拟可以非常准确。 该项目从运行各种操作系统和应用程序工作负载的各种计算机系统中收集和分发准确和有代表性的跟踪数据。 跟踪数据是使用商业逻辑分析仪和以前开发的硬件监视器收集的，该监视器已经成功地从各种机器上收集了数十亿个地址的跟踪。 一旦收集到跟踪信息，将使用大型磁盘管理和存储跟踪信息 阵列和自动磁带，并通过万维网、磁带和CD-ROM提供给用户。
