摘要： A processor has multiple cores with each core having an associated function to support processor operations. The functions performed by the cores are selectively altered to improve processor operations by balancing the resources applied for each function. For example, each core comprises a field programmable array that is selectively and dynamically programmed to perform a function, such as a floating point function or a fixed point function, based on the number of operations that use each function. As another example, a processor is built with a greater number of cores than can be simultaneously powered, each core associated with a function, so that cores having functions with lower utilization are selectively powered down.

摘要： A multiprocessor system which includes automatic workload distribution. As threads execute in the multiprocessor system, an operating system or hypervisor continuously learns the execution characteristics of the threads and saves the information in thread-specific control blocks. The execution characteristics are used to generate thread performance data. As the thread executes, the operating system continuously uses the performance data to steer the thread to a core that will execute the workload most efficiently.

摘要： A design structure for a processor may be embodied in a machine readable medium for designing, manufacturing or testing a processor integrated circuit. The design structure may control heat generation in a multi-core processor. The design structure may specify that each processor core includes a temperature sensor that reports temperature information to a processor controller. The design structure may also specify that if a particular processor core exceeds a predetermined temperature, the processor controller disables that processor core to allow that processor core to cool. The design structure may also specify that the processor controller enables the previously disabled processor core when the previously disabled processor core cools sufficiently to a normal operating temperature. In this manner, a multi-core processor may avoid undesirable hot spots that impact processor life.

摘要： A method for automatically initializing the operational settings of a system from information stored within a non-volatile storage of an integrated circuit so that the operational requirements of the integrated circuit, which may be a microprocessor, are met by the system when the system is operating. During manufacturing test, environmental requirements of the integrated circuit are determined and stored within the non-volatile storage of the integrated circuit. During system initialization, environmental control values such as required operating voltage and frequency and cooling requirements are determined from the test values, which are read from the integrated circuit. The values are read by an interface of the system from an interface of the integrated circuit. System settings are controlled by the values to provide the required operating environment and the values may be captured within the system for subsequent operations and initialization sequences.

摘要： A computer implemented method, data processing system, and computer usable code are provided for burn-in testing of a multiprocessor. A process identifies a power management data set for a plurality of processor cores associated with the multiprocessor. The process selects one or more of the plurality of processor cores to form a selected set of processor cores based upon the power management data set. The process initiates a burn-in test across the selected set of processor cores. In response to a determination that all processor cores in the plurality of processor cores have not been selected, the process repeats the above selecting and initiating steps until all the processor cores have been selected.
