Project AbstractCRI-CI-ADDO-EN:National File System Trace Repository One of the most effective ways to study computer file systems is through the use of traces, which are records of the actual operations that a computer performed on a hard disk or a set of files. For example, a trace might show that a user launched a word processor on a document, saved it three times over a period of 20 minutes, used a Web browser to retrieve an image from the Internet, inserted that image into the document, and saved it a fourth time. By analyzing traces of this sort, researchers can determine how to design file systems to provide users with optimal performance and reliability. In addition, researchers can replay a trace to reproduce the activity generated by a live user, allowing them to test new designs without the expense and difficulty of experimenting with real subjects. However, collecting traces is itself a challenging activity, so once a researcher has acquired a trace, it is desirable to share it with others. Trace sharing also allows diverse researchers to test their systems under consistent, reproducible conditions, so that different ideas can be compared and evaluated fairly. Unfortunately, there has never been a reliable source of traces, so that researchers have often been forced to use ad hoc methods to test their systems, or to use outdated traces that aren't representative of modern computer systems. To alleviate these difficulties, we are building a national repository of file system traces. The repository is designed so that it can eventually hold every trace that has ever been collected, both historical and modern, and so that it will be easy for researchers to upload, download, share, analyze, and replay any trace in the collection. A standardized format will make traces easy to manipulate, and software tools for that purpose will be made available to researchers. In the current project, NSF has provided seed funding to allow Harvey Mudd College and its collaborators to create a prototype of the repository, demonstrate its feasibility, and show that researchers will find it useful.

cri - ci - addo - en：国家文件系统跟踪库研究计算机文件系统最有效的方法之一是通过使用跟踪，跟踪是计算机在硬盘或一组文件上执行的实际操作的记录。例如，跟踪可能显示用户在文档上启动了文字处理器，在20分钟内保存了三次，使用Web浏览器从Internet检索图像，将该图像插入文档，并保存了第四次。通过分析这类跟踪，研究人员可以确定如何设计文件系统，为用户提供最佳的性能和可靠性。此外，研究人员可以重放跟踪，以重现一个活生生的用户产生的活动，使他们能够测试新的设计，而无需在真实对象上进行实验的费用和困难。然而，收集痕迹本身就是一项具有挑战性的活动，因此，一旦研究人员获得了痕迹，就希望与他人分享。痕迹共享还允许不同的研究人员在一致的、可重复的条件下测试他们的系统，从而可以公平地比较和评估不同的想法。不幸的是，从来没有可靠的痕迹来源，因此研究人员经常被迫使用特别的方法来测试他们的系统，或者使用过时的痕迹，这些痕迹不能代表现代计算机系统。为了减轻这些困难，我们正在建立一个全国性的文件系统跟踪库。存储库的设计使其最终能够保存所有已收集的痕迹，无论是历史的还是现代的，因此研究人员可以轻松地上传、下载、共享、分析和重播收集中的任何痕迹。标准化的格式将使痕迹易于操作，并且为此目的的软件工具将提供给研究人员。在目前的项目中，美国国家科学基金会提供了种子资金，让哈维马德学院及其合作者创建一个存储库的原型，证明其可行性，并向研究人员展示它的实用性。
