Abstract
Provided is a method and apparatus for ensuring a deterministic execution characteristic of an application program to perform data processing and execute particular functions in a computing environment using a micro architecture. A lock controlling apparatus based on a deterministic progress index (DPI) may include a loading unit to load a DPI of a first core and a DPI of a second core among DPIs of a plurality of cores at a lock acquisition point in time of each thread, a comparison unit to compare the DPI of the first core and the DPI of the second core, and a controller to assign a lock to a thread of the first core when the DPI of the first core is less than the DPI of the second core and when the second core corresponds to a last core to be compared among the plurality of cores.
