Abstract

The invention provides a method for detecting a parallel program shared data class bug. The method includes the steps of defining instant Fetter sets for dynamic examples of all instructions in software invariants, obtaining containing sets and obligation sets of the instant Fetter sets, conducting pruning on the containing sets and the obligation sets to obtain pruned results, storing the pruned results in an invariant database, detecting each instant Fetter set through a detection assembly to find out whether the first instant Fetter set which does not satisfy the corresponding containing set or the corresponding obligation set occurs or not, if yes, judging that the first instant Fetter set contains the bug and generating a violation report through the detection assembly, and suspending a thread which runs at present so that the detected bug can be prevented from running, wherein the software invariants refer to instruction sets with the pre-fixed execution sequence in a program. According to the method, the potential shared data class bug in the program can be automatically detected and prevented. The invention further provides a system for detecting the parallel program shared data class bug.
