Apparatus and method for thread progress tracking using deterministic progress index
Abstract:
Provided is a method and apparatus for measuring a performance or a progress state of an application program to perform data processing and execute particular functions in a computing environment using a micro architecture. A thread progress tracking apparatus may include a selector to select at least one thread constituting an application program; a determination unit to determine, based on a predetermined criterion, whether an instruction execution scheme corresponds to a deterministic execution scheme having a regular cycle or a nondeterministic execution scheme having an irregular delay cycle with respect to each of at least one instruction constituting a corresponding thread; and a deterministic progress counter to generate a deterministic progress index with respect to an instruction that is executed by the deterministic execution scheme, excluding an instruction that is executed by the nondeterministic execution scheme.
