ABSTRACT:
A method is described of managing nodes in a computer cluster comprising: each node repeatedly broadcasting a cluster summary message; a cluster coordinator node identifying failed nodes by analysing cluster summary messages received from other nodes in the cluster; and the cluster coordinator node broadcasting an updated cluster organization status, if failed nodes are identified. In at least preferred embodiments, the broadcasts can be transmitted using an ad-hoc wireless network.
