DATA DEPENDENCE ANALYZER, INFORMATION PROCESSOR, DATA DEPENDENCE ANALYSIS METHOD, AND PROGRAM

摘要

The data dependence analyzer has an inter-process communication detection means which detects inter-process communication for exchanging data to be copied between resources based on processing content in the inter-process communication, an access detection means which sequentially detects access events to the data in the aforementioned resources by the processes, a recording means which records target data to be accessed during said events for each of the aforementioned access events detected by the aforementioned access detection means, and an analysis means which retrieves data corresponding to the copy source and the copy destination of the aforementioned data exchanged in the aforementioned inter-process communication detected by the aforementioned inter-process communication detection means from the aforementioned target access data recorded by the aforementioned recording means, and which assigns dependence relationships between the retrieved data.
