71results about How to "Balance workload" patented technology

A method and system for measuring performance and balancing workload of sites, virtual clusters and servers within the virtual clusters is provided. A monitor measures and computes performance metrics at each level. Servers e.g., LDAP servers, are individually measured for performance, e.g., response time, and based on average response time of servers that are members of a virtual cluster, a virtual cluster performance metric may also be computed. Further, the performance of a site may be profiled based on the virtual cluster metrics and/or server performance metrics. Based at least in part on these performance metrics, a domain oriented request may be resolved and routed based in part on the performance metrics at each level, i.e., site, virtual cluster and server. In this manner, a request may be directed to a destination server to achieve higher performance and efficiencies for the requesting client while at the same time balancing workload among possible servers available to service the request.

Techniques allow a client to be switched from a session on a server to another session on another server in a way that is a transparent to the application for which the initial session was established. Thus, under transparent session migration, a client is switched between sessions without executing application instructions tailored to accomplish the migration. Instead, a client-side interface component, through which the application interacts with the server, handles details of migration, modifying the internal state of the client-side interface component to effect the same. Legacy applications do not have to be modified in order to institute techniques described herein.

A method of providing a single system image in a clustered environment. An internet protocol (IP) address is assigned as a cluster IP address. The cluster IP address is bound to a node in a cluster. A client request directed to the cluster IP address is received in the node. The node multicasts the request to all nodes in the cluster. A dynamically adjustable workload distribution function filters the request, wherein the function is configured to allow a single node to process the client request. A response to the request is obtained. A cluster media access control (MAC) address is inserted into the response and the response is sent from the single node to the client.

A tree-structured index to multidimensional data is created using occurring patterns and clusters within the data which permit efficient search and retrieval strategies in a database of DNA profiles. A search engine utilizes hierarchical decomposition of the database by identifying clusters of similar DNA profiles and maps to parallel computer architecture, allowing scale up past previously feasible limits. Key benefits of the new method are logarithmic scale up and parallelization. These benefits are achieved by identification and utilization of occurring patterns and clusters within stored data. The patterns and clusters enable the stored data to be partitioned into subsets of roughly equal size. The method can be applied recursively, resulting in a database tree that is balanced, meaning that all paths or branches through the tree have roughly the same length. The method achieves high performance by exploiting the natural structure of the data in a manner that maintains balanced trees. Implementation of the method maps to parallel computer architectures, allowing scale up to very large databases.

A method and associated systems for the environmentally aware load-balancing of components of a multi-component power-consuming system. The environmentally aware load-balancer receives continually updated values from at least two environmental sensors that monitor and report the values of environmental metrics that characterize components of the power-consuming system and the environments within which those components are located. When the load-balancer receives a task request directed to the power-consuming system, the load-balancer selects a balanced workload allocation as a function of the values of the received environmental metrics and communicates that balanced workload allocation to a routing mechanism. The routing mechanism then uses the communicated balanced workload allocation to determine which component or components of the power-consuming system should receive the task request.
