Dynamic formation of symmetric multi-processor (SMP) domains

摘要

Symmetric multi-processor (SMP) nodes are dynamically configured via SMP sockets that use SMP optically-connected switches to dynamically connect SMP optically-connected links connected to the SMP nodes to form SMP domains based on best matched expected workloads for coherent traffic for exchanging SMP coherent information. The SMP nodes are dynamically added to one of the SMP domains and/or dynamically removed from one of the SMP domains.

1. A method for dynamic formation of symmetric multi-processor (SMP) domains in an optically-connected system having an optical switch in a computing environment, comprising:
dynamically configuring together a plurality of SMP nodes via a plurality of SMP sockets that use the optical switch to dynamically connect a plurality of SMP optically-connected links connected to the plurality of SMP nodes to form a plurality of SMP domains based on best matched expected workloads for coherent traffic for exchanging SMP coherent information, wherein the plurality of SMP domains each have at least two of the SMP optically-connected links connected through the optical switch, and the at least two SMP optically-connected links for each SMP domain are split to be separate from the at least two SMP optically-connected links of others of the plurality of SMP domains, such that each SMP domain has its own coherent traffic and such that a workload of each of the SMP domains is isolated from workloads of other SMP domains of the plurality of SMP domains; and performing one of:
dynamically adding one of the plurality of SMP nodes to the one of the plurality of SMP domains, anddynamically removing the one of the plurality of SMP nodes from the one of the plurality of SMP domains.
