摘要： Methods and apparatuses for developing symmetric and asymmetric software applications on a single monolithic symmetric multiprocessing operating system are disclosed. An enabling framework for one or all of the following software design patterns; application work load sharing between all processors present in a multi-processor system in a symmetric fashion, application work load sharing between all processors present in a multi-processor system in a asymmetric fashion using task to processor soft affinity declarations, application work load sharing between all processors present in a multi-processor system using bound computational domains may be provided. Further, a particular computational task or a set of computational tasks may be bound to a particular processing unit. Subsequently, when one such task is to be scheduled, the symmetric multiprocessing operating system ensures that the bound processing unit processes the instruction. When the bound processing unit is not processing the particular computational instruction, the bound processing unit may enter a low power or idle state.
