摘要： Disclosed are methods, apparatus and computer programs for improving performance and resource utilization of cluster-based data processing systems. The number of persistent connections between first and second data processing units of a system is adjusted according to monitored performance of communications between the nodes. The monitored performance measure is the queuing delay between the nodes, and the number of connections is increased and decreased as changing load conditions increase and decrease the queuing delay. A method of establishing and closing persistent connections in response to a monitored queuing delay between a front-end gateway computer and each of a cluster of back-end servers is used to improve the performance of a cluster-based Web server or provision of Web services. Unwanted connections are closed to enable system resources to be allocated to other processes.
摘要翻译：公开了用于提高基于群集的数据处理系统的性能和资源利用的方法，装置和计算机程序。系统的第一和第二数据处理单元之间的持续连接的数量根据节点之间的通信监视的性能进行调整。监测的性能测量是节点之间的排队延迟，随着负载条件的增加和排队延迟的增加，连接数量也增加和减少。使用响应于前端网关计算机和后端服务器群集之间的受监视的排队延迟建立和关闭持久连接的方法来提高基于群集的Web服务器或提供Web服务的性能。关闭不需要的连接，以便将系统资源分配给其他进程。

摘要： Decentralized orchestration of composite services results in a number of flow topologies which differ in their messaging patterns and the distribution of flow code amongst different partitions of a topology. Different performance metrics result for different topologies, and this is governed by the availability of resources, such as CPU cycles, memory, network bandwidth, and so on. A performance model is used to evaluate the performance of different topologies based on availability of resources, and dynamically direct client requests between different topologies according to prevailing conditions.

摘要： Systems and methods execute a computer program to produce a trace of the computer program and divide the trace into independent threads of execution. Each of the independent threads of execution comprises an execution sequence of the lines of programming code that ends with an identified write line of programming code that outputs an incorrect result. These systems and methods also identify key field within each of the independent threads of execution. In programming, which is processing records in a table one by one, key-fields are a subset of the fields of the table. The key fields impact the computations sequence leading up to the identified write line of the programming code. These systems and methods identify key-based dynamic slices from the independent threads of execution. Each of the key-based dynamic slices includes lines of programming code that are used in computations, processing the table records corresponding to the key fields.
