Abstract: A method (and system) of storing data in a value-based storage system, includes optimizing a value of data stored in the value-based storage system.

Abstract: A method of choosing jobs to run in a stream based distributed computer system includes determining jobs to be run in a distributed stream-oriented system by deciding a priority threshold above which jobs will be accepted, below which jobs will be rejected. Overall importance is maximized relative to the priority threshold based on importance values assigned to all jobs. System constraints are applied to ensure jobs meet set criteria.

Abstract: An apparatus and method for making fractional assignments of processing elements to processing nodes for stream-based applications in a distributed computer system includes determining an amount of processing power to give to each processing element. Based on a list of acceptable processing nodes, a determination of fractions of which processing nodes will work on each processing element is made. To update allocations of the amount of processing power and the fractions, the process is repeated.

Abstract: Techniques for community discovery in a network are disclosed. For example, a technique for discovering a community around a given entity in an interaction graph, wherein nodes in the graph represent entities and edges connecting nodes in the graph represent interactions between connected nodes, comprises the following steps/operations. Nodes in the interaction graph are partitioned into different sets of nodes based on interaction information associated with each node to minimize a number of interaction pairs that need to be considered. An objective function is minimized by moving entities between the different sets such that the community is discovered once a measure associated with the objective function is minimized.
