Abstract: In a method of improving querying, a plurality of items of information are transformed into a plurality of vectors, where each item of information of the plurality of items of information is mapped to a respective vector of said plurality of vectors. A plurality of vectors is associated with a subset of nodes selected from a plurality of nodes. Each vector associated with a respective node of said plurality of nodes is based on a similarity between each vector of said plurality of vectors.

Abstract: A peer-to-peer system includes a destination node operable to receive a query. The destination node receives samples from a first set of nodes proximally located to the destination node in an overlay network for the peer-to-peer system. The samples are associated with information stored at the proximally located nodes. The destination node is operable to identify, based on the samples received from the first set of nodes, a first node of the first set of nodes likely storing information associated with objects stored in the peer-to-peer system that are relevant to the query.

Abstract: A method for determining an application instance placement in a set of machines under one or more resource constraints includes the following steps. An estimate is computed of a value of the first metric that can be achieved by a current application instance placement and a current application load distribution. A new application instance placement and a new application load distribution are determined, wherein the new application instance placement and the new load distribution optimize the first metric.

Abstract: 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.
Abstract translation: 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。

Abstract: An overlay network is used to logically represent an underlying physical network. A network condition is monitored by a node in a target region of the network. If the network condition occurs, the node transmits a notification to a source node including location information for nodes physically close in the physical network. The source node may select a routing node in the target region based on the location information.
Abstract translation: 覆盖网络用于逻辑地表示底层物理网络。 网络条件由网络的目标区域中的节点监视。 如果发生网络状况，则节点向源节点发送包括物理网络物理接近的节点的位置信息的通知。 源节点可以基于位置信息来选择目标区域中的路由节点。

Abstract: A decentralized process to ensure the dynamic placement of applications on servers under two types of simultaneous resource requirements, those that are dependent on the loads placed on the applications and those that are independent. The demand (load) for applications changes over time and the goal is to satisfy all the demand while changing the solution (assignment of applications to servers) as little as possible.
Abstract translation: 一种分散的过程，以确保在两种类型的同时资源需求下的服务器上的应用程序的动态放置，那些依赖于应用程序上的负载和独立的负载。 应用程序的需求（负载）随时间而变化，目标是尽可能少地改变解决方案（将应用程序分配给服务器）来满足所有需求。
