EFFICIENT CACHE REUSE THROUGH APPLICATION DETERMINED SCHEDULING

A method of determining a thread from a plurality of threads to execute a task in a multi-processor computer system. The plurality of threads is grouped into at least one subset associated with a cache memory of the computer system. The task has a type determined by a set of instructions. The method obtains an execution history of the subset of plurality of threads and determines a weighting for each of the set of instructions and the set of data, the weightings depending on the type of the task. A suitability of the subset of the threads to execute the task based on the execution history and the determined weightings, is then determined. Subject to the determined suitability of the subset of threads, the method determining a thread from the subset of threads to execute the task using content of the cache memory associated with the subset of threads.
