Patent ID: 7379418

Claim:
A method for use in multiprocessor multi-nodal system of serializing requests to ensure system quiesce, comprising the steps of: concurrently adding or removing a node using local processor nodes of a local ring topology having adaptive logic for responses during system operation and each node of said local ring topology being only aware of up to two adjacent nodes on said local ring while: a. causing enabled local processor adaptive quiesce logic on a node's system topology network interface to dynamically respond and identify the role of it's node by identification of a node within the overall multi-processor multi-nodal system based on bus inter-connectivity; b. accumulating responses from the local processors, and propagating a quiesce signal indicator from said node's system topology network interface to adjacent nodes as directed by said role of it's node within the overall multi-processor multi-nodal system; c. informing the local processors of system quiesce upon receipt of all remote quiesce indicators.
