Relacy Race Detector is a tool for efficient execution of unit-tests for synchronization algorithms written in C++0x.Every user thread is represented as a fiber (ucontext). Every time only one fiber is running, and special scheduler controls interleaving between fibers. With random scheduler it just executes numerous amount of various interleavings between threads. With full search scheduler or context-bound scheduler it systematically executes all possible interleavings between threads. While e...
