Abstract
A computer-implemented method, computer-readable media, and a computerized system to track and detect data hazards are provided. The computerized system includes processors configured to execute instructions associated with a multithreaded program. The computerized system allocates memory for the multithreaded program and creates threads for execution on the processors. The memory may include a reserved area for tracking information. The threads access the allocated memory in accordance with the multithreaded program and the memory including the tracking information is updated based on the threads' memory access. In turn, the processors generate notifications of data hazard based on the tracking information stored in the allocated memory.
