cpuplugd - Control CPUs and memory
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.
Note: Do not use cpuplugd with NUMA emulation.
cpuplugd can distort the balance of CPU assignments to NUMA nodes.
You can start cpuplugd
from the command line in two ways:
- With the service utility
- From a command line
Note: Do not run multiple instances of cpuplugd simultaneously.
