摘要： An apparatus and method for efficiently performing a query sort on a data set with duplicate key values is disclosed. The method includes identifying unique key values for a key in a data set after determining that a number of duplicate key values for the key exceed a predefined threshold. The method also includes recording an association of each unique key value with a record in the data set and sorting unique key values. The method further includes storing the unique key values in a sorted order, wherein each unique key value is associated with an appropriate record in the data set.

摘要： Improved techniques are disclosed for use in an intrusion prevention system or the like. For example, a method comprises the following steps performed by a computing element of a network. A packet of a flow is received, the flow comprising a plurality of packets, wherein the plurality of packets represents data in the network. A network intrusion analysis cost-benefit value is determined representing a benefit for analyzing the received packet for intrusions in relation to a cost for analyzing the received packet for intrusions. The method compares the network intrusion analysis cost-benefit value to a network intrusion analysis cost-benefit threshold to determine whether analyzing the received packet for intrusions before forwarding the received packet is warranted. Responsive to a determination that analyzing the received packet for intrusions before forwarding the received packet is not warranted, the received packet is forwarded, an indication is made that subsequent packets of the flow should be forwarded, and a determination is made whether the received packet indicates an intrusion after forwarding the received packet.

摘要： Techniques for encoded data processing which allow for continuous data processing as encoded data changes. Data is decomposed into one or more blocks with each block containing at least one data record. At least one data record within a given block is encoded with a first encoding process selected from one or more encoding processes. The first encoding process is associated with the given data block. Techniques evaluate whether or not to implement an encoding change for a given block when updating a given data record in the given block. Responsive to the evaluation, the given block is re-encoded with a second encoding process. Responsive to the re-encoding, the association of the given block is updated. A map is formed to convert the given data record encoded with the first encoding process to the second encoding process so as to preserve comparative relationships of the given data record.

摘要： Power consumption in a microprocessor platform is managed by setting a peak power level for power consumed by a multi-core microprocessor platform executing multi-threaded applications. The multi-core microprocessor platform contains a plurality of physical cores, and each physical core is configurable into a plurality of logical cores. A simultaneous multithreading level in at least one physical core is adjusted by changing the number of logical cores on that physical core in response to a power consumption level of the multi-core microprocessor platform exceeding the peak power level. Performance and power data based on simultaneous multi-threading levels are used in selecting the physical core to be adjusted.
