CSR: Small: Wisconsin Next Generation benchmarks (WiNG)

对文件和存储系统进行基准测试具有挑战性。威斯康星州下一代基准测试(WING)项目旨在提供工具和技术来简化文件和存储系统的基准测试，特别是在大规模和存储容量方面。WING项目解决了当前基准文件系统中的三个问题。首先，文件系统的性能可能对磁盘上文件的初始分配非常敏感。我们的Impressions框架可帮助评估人员轻松快速地创建具有代表性的、可重现的文件系统映像，以初始化测试中的系统。其次，评估人员希望了解文件系统在大型数据集上的性能；遗憾的是，获取必要的存储容量和运行工作负载所需的时间可能非常昂贵。压缩有助于扩展：它使用户能够使用小得多的存储系统对极大的数据集进行基准测试，并且在某些情况下可将基准测试运行时间缩短数量级。第三，评估人员很少有专业知识来设置和运行一系列有趣的代表性应用程序。Insight使用户能够轻松创建和运行代表更复杂应用程序的合成工作负载。总而言之，WING使开发人员能够评估实际用户关心的应用程序上的文件系统。WING正在开发能够并将被文件系统社区使用的基准基础设施和源代码。翼为研究生提供具有尖端系统技术的实践培训。最后，为了扩展到更广泛的社区，WING使本科生能够在Scratch编程环境中与小学生一起工作。

Benchmarking file and storage systems is challenging. The Wisconsin Next Generation Benchmarks (WiNG) project aims to provide tools and techniques to simplify the benchmarking of file and storage systems, particularly at large scales and storage capacities. The WiNG project solves three current problems in benchmarking file systems.First, the performance of file systems can be extremely sensitive to the initial allocation of files on disk. Our Impressions framework helps evaluators to easily and quickly create representative, reproducible file system images to initialize the system under test.Second, evaluators want to understand how file systems perform on large data sets; unfortunately, it can be costly to acquire the necessary storage capacity and time consuming to run the workloads. Compressions helps with scale: it enables users to benchmark extremely large data sets using significantly smaller storage systems and for some scenarios reduces benchmark running time by orders of magnitude.Third, evaluators rarely have the expertise to set up and run an interesting range of representative applications. Insight enables users to easily create and run synthetic workloads representative of more complex applications.In summary, WiNG enables developers to evaluate file systems on applications that real users care about. WiNG is developing benchmarking infrastructure and source code that can and will be used by the file system community. WiNG gives graduate students hands-on training with cutting-edge systems technology. Finally, for outreach to the wider community, WiNG enables an undergraduate to work with elementary-school children in the Scratch programming environment.
