摘要： An apparatus and method for detecting a data race of a multithread system is provided. A thread may be divided into an open sub region or a closed sub region according to a vector clock and an execution state. In order to detect a data race before the execution is terminated, when an open sub region is converted to a closed sub region, a memory access event corresponding to the closed sub region is investigated and a memory access event having no parallel relation with an open sub region is deleted among memory access events having been subject to the investigation.
