Abstract
Systems and methods that allow for dynamically deconfiguring, reconfiguring and/or otherwise configuring nodes (e.g., processors) in a symmetric multiprocessing system (e.g., a symmetric multiprocessor) in a manner that avoids, or at least limits, inefficiencies such as renumbering of node IDs, system reboots, SW configuration handle changes, and the like. In one arrangement, a number of modules, tables and/or the like that are configured to generate node IDs and/or convert node IDs from one form to another form can be intelligently implemented within an SMP to allow the various processes and/or components of an SMP to utilize the node IDs in a more efficient manner. For instance, as SDs in an SMP are often configured to work with CNIDs (e.g., for use in determining at which node a particular requested cache line resides), any node GNIDs that are sent to the SD for processing can first be converted into corresponding CNIDs.
