Method, apparatus, and computer program product for adaptive process dispatch in a computer system having a plurality of processors

摘要

A run-time feature set of a process or a thread is generated and compared to at least one processor feature set. Each processor feature set represents zero or more optional hardware features supported by one or more processors, whereas the run-time feature set represents zero or more optional hardware features the process or thread relies upon. The comparison of the feature sets determines whether a particular process or thread may run on a particular processor, even in a heterogeneous processor environment. A system task dispatcher assigns the process or thread to execute on one or more processors indicated by the comparison as being compatible with the process or thread. When a new feature is added to the process or thread, the run-time feature set is updated and again compared to at least one processor feature set. The system task dispatcher reassigns the process or thread if necessary.
