1. A method, comprising: detecting, by a compute node in response to a hot-plug reset instruction, one or more processors of the compute node; generating, by the compute node, a unique ID value for each detected processor to assign a unique ID value to each respective processor of the compute node to enable enumeration of the detected processors of the compute node to an operating system of a system architecture in which the compute node is hot plugged; issuing, by the compute node, hot plug notification to the operating system; and starting, in response to an operating system activation request, the one or more processors of the compute node.
