Specific Assignment of CPUs, Cores, and Sockets

Use the subcommands assign and unassign assign specific CPUs, cores, and sockets.

The assign and unassign subcommands are applicable to both the persistent and runtime configurations of the pools. Using the assign subcommand and setting pset.min and pset.max directly are mutually exclusive. Each method overwrites the configuration set by the other.

CPUs configured to processor sets using the pset.min and pset.max properties are considered allocated rather than assigned. The assign and unassign subcommands add and remove specific CPUs to or from a pset, respectively. The first assign clears any pset element configuration set up by a previous allocation. Use the unassign subcommand only after a successful assign operation.

The unassign subcommand cannot be used to manipulate CPUs from allocated processor sets.
