A response-time-difference calculation / request-number converting means (523) calculates a change of throughput based on a response time monitoring result, a target value of the response time, a quantitative model and performance specification information. A server selection means (524) input the performance specification information in the quantitative model acquired to calculate a throughput of each of pool servers, selects a pool server having a throughput corresponding to a throughput larger than and closest to the change of throughput, and instructs provisioning means (513) to execute configuration modification control on the selected pool server (502). The provisioning means (513) modifies the configuration so that the pool server (502) functions as an application server.

A system and method that does trustworthy multi-objective structural synthesis of analog circuits, and extracts expert analog circuit knowledge from the resulting tradeoffs. The system defines a space of thousands of possible topologies via a hierarchically organized combination of designer-trusted analog building blocks, the resulting topologies are guaranteed trustworthy. The system can perform a search based on a multi-objective evolutionary algorithm that uses an age-layered population structure to balance exploration vs. exploitation, with operators that make the search space a hybrid between vector-based and tree-based representations. A scheme employing average ranking on Pareto fronts is used to handle a high number of objectives. Good initial topology sizings are quickly generated via multi-gate constraint satisfaction. To explicitly capture expert analog design knowledge, data mining is employed on the sized circuits to: automatically generate a decision tree for navigating from performance specifications to topology choice, to do global nonlinear sensitivity analysis, and to generate analytical models of performance tradeoffs.

Packaged integrated circuits (ICs) of some types, such as processors, are graded and sold according to a performance scale, such as maximum specified clock speed, set by the manufacturer as a result of testing. As a record of this grading some part of the package, usually the upper surface, is marked with the specified performance attribute. However, criminal activity has developed where the packaging is relabelled to show a higher specification so the ICs can be fraudulently resold at a higher price. To address this problem, the invention envisages that manufacturers maintaining a product database for each packaged IC which logs not only the performance specification, but also a digital signature derived from a speckle pattern obtained from the packaging. Subsequently, any packaged IC can be rescanned to interrogate its speckle pattern and recompute the signature. The signature is then used to find the product in the database, whereby the originally specified performance attribute is retrieved. The fraud is then detectable. This method can be used to test products returned under a warranty claim, for example.

Methods and circuits for optimizing performance and power consumption in a circuit design and circuit employing one or more lower threshold voltage (Lvt) cells or devices are described. A base supply voltage amplitude is determined for providing operating power for the circuit. The base supply voltage amplitude is a low or lowest voltage level that still satisfies a performance specification for the circuit. Providing a low or lowest base supply voltage level reduces or minimizes the standby (i.e., non-switching) power consumption in the Lvt device(s) since current leakage is reduced as the supply voltage level is reduced. Reducing the supply voltage level used to power the Lvt device(s) also reduces active power consumption for the circuit as well. Thus, total power consumption is optimized or reduced while still receiving the benefit of using Lvt devices to optimize or increase performance of a circuit layout and circuit.
