Description

Contention Guard (CGUARD)

The Contention Guard (CGuard) is a safety mechanism for monitoring and controlling the impact of multicore timing interference. The mechanism has been designed to control and mitigate memory contention situations by stopping non-critical tasks’ memory usage if necessary. The tool is integrated within the SAFEXPLAIN middleware layer by extending the C++ BaseApplication middleware class to support the definition of critical and non-critical applications (as the CriticalApplication and NonCriticalApplication classes), and introducing the C++ ContentionGuard class to monitor these applications and apply the mechanism (i.e., decide whether to stop the NonCriticalApplication).
The provided package includes a minimal and illustrative example.
