4.2. Tuning CPUs with Tuna
Tuna commands can target individual CPUs. To list the CPUs on your system, see the Monitoring tab in Tuna GUI or the
/proc/cpuinfo file for detailed information.
To specify the list of CPUs to be affected by your command, use:
#tuna --cpus=cpu_list --command
Isolating a CPU causes all tasks currently running on that CPU to move to the next available CPU. To isolate a CPU, use:
#tuna --cpus=cpu_list --isolate
Including a CPU allows threads to run on the specified CPU. To include a CPU, use:
#tuna --cpus=cpu_list --include
The cpu_list argument is a list of comma-separated CPU numbers. For example,
--cpus=0,2.
