摘要： On demand image streaming (ODS), in one aspect, may perform both copy-on-write and copy-on-read to gradually bring data on remote storage server to a host's local disk. Prefetching may be performed during the time the resources are otherwise idle to bring in data from the remote storage server to the host's local disk. A new image format and the corresponding block device driver for a hypervisor or the like may be also provided. ODS' image format may include a header and a bitmap that indicates whether the data sectors are on local disk or remote storage server, and an image content, for instance, stored in raw format.
摘要翻译：按需图像流（ODS），在一个方面，可以执行写时复制和读写操作，以便将远程存储服务器上的数据逐渐带到主机的本地磁盘。可以在资源闲置的时间内执行预取，以将数据从远程存储服务器引入主机的本地磁盘。还可以提供新的图像格式以及用于管理程序等的相应的块设备驱动程序。 ODS的图像格式可以包括标题和位图，其指示数据扇区是在本地磁盘还是远程存储服务器上，并且图像内容例如以原始格式存储。

摘要： Throughput of a high-volume throughput-centric computer system is controlled by dynamically adjusting a concurrency level of a plurality of events being processed in a computer system to meet a predetermined target for utilization of one or more resources of a computer system. The predetermined target is less than 100% utilization of said one or more resources. The adjusted concurrency level is validated using one or more queuing models to check that said predetermined target is being met. Parameters are configured for adjusting the concurrency level. The parameters are configured so that said one or more resources are shared with one or more external programs. A statistical algorithm is established that minimizes total number of samples collected. The samples may be used to measure performance used to further dynamically adjust the concurrency level. A dynamic thread sleeping method is designed to handle systems that need only a very small number of threads to saturate bottleneck resources and hence are sensitive to concurrency level changes.
摘要翻译：通过动态地调整在计算机系统中正在处理的多个事件的并发级别以满足计算机系统的一个或多个资源的使用的预定目标来控制大容量以吞吐量为中心的计算机系统的吞吐量。所述预定目标小于所述一个或多个资源的100％利用率。使用一个或多个排队模型验证所调整的并发级别，以检查是否满足所述预定目标。配置参数以调整并发级别。参数被配置为使得所述一个或多个资源与一个或多个外部程序共享。建立统计算法，使收集的样本总数最小化。样本可用于测量用于进一步动态调整并发级别的性能。动态线程休眠方法旨在处理只需要非常少量线程的系统，从而使瓶颈资源饱和，因此对并发级更改敏感。

摘要： A data model represents semantic information associated with objects stored in a file system. The data model includes a first object identifier, a second object identifier and a relation identifier. The first object identifier identifies a first object stored in the file system. The second object identifier identifies a second object stored in the file system, wherein the second object is related to the first object. The relation identifier identifies a relationship between the first object and the second object.
