Accelerating Dynamic Data Race Detection Using Static Thread Interference Analysis

Precise dynamic race detectors report an error if and only if more than one thread concurrently exhibits conflict on a memory access. They insert instrumentations at compile-time to perform runtime checks on all memory accesses to ensure that all races are captured and no spurious warnings are generated. However, a dynamic race check for a particular memory access statement is guaranteed to be redundant if the statement can be statically identified as thread interference-free. Despite significant recent advances in dynamic detection techniques, the redundant check remains a critical factor that leads to prohibitive overhead of dynamic race detection for multithreaded programs.
