摘要： A directory-based coherency method, system and program are provided for intervening a requested cache line from a plurality of candidate memory sources in a multiprocessor system on the basis of the sensed temperature or power dissipation value at each memory source. By providing temperature or power dissipation sensors in each of the candidate memory sources (e.g., at cores, cache memories, memory controller, etc.) that share a requested cache line, control logic may be used to determine which memory source should source the cache line by using the power sensor signals to signal only the memory source with acceptable power dissipation to provide the cache line to the requester.

摘要： A multiprocessor system having plural heterogeneous processing units schedules instruction sets for execution on a selected of the processing units by matching workload processing characteristics of processing units and the instruction sets. To establish an instruction set's processing characteristics, the homogeneous instruction set is executed on each of the plural processing units with one or more performance metrics tracked at each of the processing units to determine which processing unit most efficiently executes the instruction set. Instruction set workload processing characteristics are stored for reference in scheduling subsequent execution of the instruction set.

摘要： A processor having multiple cores coordinates functions performed on the cores to automatically, dynamically and repeatedly reconfigure the cores for optimal performance based on characteristics of currently executing software. A core running a thread detects a multi-core characteristic of the thread and assigns one or more other cores to the thread to dynamically combine the cores into what functionally amounts to a common core for more efficient execution of the thread.

摘要： A method, system and program are provided for dynamically reconfiguring a pipelined processor to operate with reduced power consumption without reducing existing performance. By monitoring or detecting the performance of individual units or stages in the processor as they execute a given workload, each stage may use high-performance circuitry until such time as a drop in the throughput performance is detected, at which point the stages are reconfigured to use lower-performance circuitry so as to meet the reduced performance throughput requirements using less power. By configuring the processor to back off from high-performance designs to low-performance designs to meet the detected performance characteristics of the executing workload warrant, power dissipation may be optimized.

摘要： A method, system and program are provided for dynamically assigning priority values to instruction threads in a computer system based on one or more predetermined thread performance tests, and using the assigned instruction priorities to determine how resources are used in the system. By storing the assigning priority values for each thread as a tag in the thread's instructions, tagged instructions from different threads that are dispatched through the system are allocated system resources based on the tagged priority values assigned to the respective instruction threads. Priority values for individual threads may be updated with control software which tests thread performance and uses the test results to apply predetermined adjustment policies. The test results may be used to optimize the workload allocation of system resources by dynamically assigning thread priority values to individual threads using any desired policy, such as achieving thread execution balance relative to thresholds and to performance of other threads, reducing thread response time, lowering power consumption, etc.

摘要： A method, system and program are provided for dynamically assigning priority values to instruction threads in a computer system based on one or more predetermined thread performance tests, and using the assigned instruction priorities to determine how resources are used in the system. By storing the assigning priority values in thread priority registers distributed throughout the computer system, instructions from different threads that are dispatched through the system are allocated system resources based on the priority values assigned to the respective instruction threads. Priority values for individual threads may be updated with control software which tests thread performance and uses the test results to apply predetermined adjustment policies. The test results may be used to optimize the workload allocation of system resources by dynamically assigning thread priority values to individual threads using any desired policy, such as achieving thread execution balance relative to thresholds and to performance of other threads, reducing thread response time, lowering power consumption, etc.

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.

The system includes a processor and a cache hierarchy, where the cache hierarchy includes a sectored upper level cache and an unsectored lower level cache, and wherein the upper level cache includes a plurality of sub-sectors, each sub-sector having a cache line size corresponding to a cache line size of the lower level cache. The system also includes logic executable to, responsive to determining that a cache line from the upper level cache is to be evicted to the lower level cache: identify referenced sub-sectors of the cache line to be evicted; invalidate unreferenced sub-sectors of the cache line to be evicted; and store the referenced sub-sectors in the lower level cache.
