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: Isolating a CPU causes all tasks currently running on that CPU to move to the available CPU. To isolate a CPU, use: Including a CPU allows threads to run on the specified CPU. To include a CPU, use: The cpu_list argument is a list of comma-separated CPU numbers. For example, --cpus=0,2 .
tuna --cpus= cpu_list --run= COMMAND tuna --cpus= cpu_list --isolate tuna --cpus= cpu_list --include
