Latest Patents

Eranian holds a patent for "Techniques and systems for data race detection." This patent describes a race detection mechanism that involves running threads of a multithreaded program on a processor. The program is designed to produce locksets, which indicate the set of one or more locks that a thread holds at a specific point in time. The mechanism utilizes a performance monitoring unit within the processor to monitor memory accesses caused by the threads. It produces samples indicative of accessed memory locations. The mechanism can detect the existence of a data race condition based on these samples and the locksets. This detection process includes identifying protected and unprotected accesses to memory locations by different threads, ultimately outputting an indication of the data race condition.
