Abstract
Counter based heartbeat messaging is implemented by storing heartbeat count vectors and health vectors of each core in a shared memory. Each core implements its heartbeat operation by storing the heartbeat count and health vectors from shared to local memory. A core uses its locally stored vectors to detect fault conditions at the other cores, and to achieve interactive consistency. Any core can initiate a system reaction to a core having a failing health status when a defined number of cores agree with that status.
