<p>A split brain avoidance protocol to determine the group of processors (112) that will survive a complete partitioning (disconnection) in the inter-processor communications (114) paths connecting processors (112) in a multi-processor system (100). Processors (112) embodying the invention detect that the set of processors (112) with which they can communicate has changed. They then choose either to halt or to continue operations, guided by the goal of minimizing the possibility that multiple disconnected groups of processors (112) continue to operate as independent systems, each group having determined (incorrectly) that the processors (112) of the other groups have failed.</p> |
