Generating concurrent test-programs with collisions for multi-processor verification

We discuss collisions that are of interest to multiprocessor verification. Collisions occur when different processes access a shared resource. We investigate how the results of such collisions can be presented in test programs and suggest implementations for automatically generating such tests and predicting the results of collision scenarios. Most of the ideas presented are the result of years of experience with two multi-processor test generators from IBM (Genie and Genesys-Pro) which are also briefly presented.
