cpuplugd - Control CPUs and memory

SUSE Linux Enterprise Server 15 SP5 LPAR mode z/VM guest KVM guest

Use the cpuplugd command and a set of rules in a configuration file to dynamically enable or disable CPUs. For Linux® on z/VM®, you can also dynamically add or remove memory.

Rules that are tailored to a particular system environment and the associated workload can increase performance. The rules can include various system load variables.

You can start cpuplugd from the command line in two ways:
  • With the service utility
  • Through a command-line interface
Note: Do not run multiple instances of cpuplugd simultaneously.
