Abstract
Systems, methods, and device are provided for symmetric multiprocessor (SMP) systems. One method embodiment includes creating a child process for each processor in the SMP. An event address register (EAR) associated with each processor is used to record information relating to cache misses. The EAR records are analyzed for each processor and a bit vector is created for each byte of cache line that is shared by multiple processors.
