Abstract
Simulator based detection of a violation of a coherency protocol in an incoherent shared memory system is disclosed. One example is a system including a simulator running on a first computing system, where the simulator simulates a second computing system that is a target for an application to be tested, and where the simulator includes a cache manager to monitor a state of a plurality of simulated caches in an incoherent memory system shared by a plurality of simulated processors, wherein the plurality of simulated processors simulate operations of a respective plurality of processors of the second computing system, and detect a violation of a coherency protocol in the shared memory system, and an alert generator to provide, via a computing device on the first computing system, an alert indicative of the violation.
