Run-Time Detection of Communication (97)
Abstract:
Abstract. A novel approach to detection of communication deadlocks in occam 2 programs is proposed. The main feature of the approach is to monitor the interprocess communications of a target occam 2 program at runtime and detect communication deadlocks in the program by operating a Process-Wait-For Graph (PWFG) of the program. The PWFG is a formal representation of the synchronization waiting situation in an occam 2 program. In addition to the principle of detecting communication deadlocks in occam 2 programs, some issues on implementation of the monitor are also discussed. 1
