Abstract:

A facility that for a multithreaded program executing on a root machine causes the threads of the program to be executed in a relative scheduling that produces an interesting result. The facility suspends execution of the program. The facility then tests a plurality of relative thread schedulings on one or more virtual machines and observes the result. Based upon the observed result the facility selects one of the tested relative thread schedulings. The facility then resumes execution of the program using the selected relative thread scheduling.
