    • 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.
    • 提供了一种用于测量应用程序的性能或进展状态以便在使用微架构的计算环境中执行数据处理并执行特定功能的方法和装置。 线程进度跟踪装置可以包括:选择器,用于选择构成应用程序的至少一个线程; 确定单元,基于预定标准,确定指令执行方案是否对应于具有规则周期的确定性执行方案或具有相对于构成对应线程的至少一个指令中的每一个指令具有不规则延迟周期的非确定性执行方案 ; 以及确定性进度计数器,用于生成关于由确定性执行方案执行的指令的确定性进度索引,不包括由非确定性执行方案执行的指令。
