First, shared variables are frequently initialized without holding a lock. In that case, the lockset algorithm will report data race, but actually there is not data race. The second case is the read-shared data. For this kind of data, they are read-only, so, there is no data race since the ...

WitrynaThe algorithm tracks the current lockset for each thread. Each lock-acquire event adds a lock to its thread’s lockset. The corresponding release removes the lock. When an access to a variable is processed, the variable’s candidate lockset is reﬁned by intersecting it with the thread’s current lockset. In other words, the algorithm sets WitrynaAlgorithms for runtime race detection make use of two key techniques: lock-sets and vector clocks. Roughly speaking, lockset-based algorithms compute at …
