APPARATUS AND METHOD FOR RACE DETECTION IN PARALLEL PROGRAMS BASED ON MULTI-CORES

摘要

The present invention relates to an apparatus and method for scalable monitoring for contention detection of a multicore-based parallel program that detects contention in parallel program execution based on multicore. An expansion monitoring apparatus for detecting contention of a multicore-based parallel program according to the present invention includes a supervisory code inserter for generating a modified original parallel program by adding an extended supervisory code to a source parallel program, A thread monitoring unit for generating a data structure of a thread generated according to the execution, an access event selector for selecting an access event by checking the possibility of competition according to the execution of the modified original parallel program, A power measurement unit for measuring and storing power data according to the execution of the source parallel program, and a power analysis unit for analyzing the power data to determine whether an energy bug has occurred.
