taskset: Set a running process' CPU affinity by PID.
$ taskset --pid --cpu-list ${cpu_id} ${pid}
try on your machine
The command "taskset --pid --cpu-list ${cpu_id} ${pid}" is used to associate a specific CPU or a group of CPUs with a given process ID (PID) on Linux.
Let's break down the command and understand its components:
- "taskset" is a command-line utility in Linux that sets or retrieves the CPU affinity of a running process.
- "--pid" is an option to specify that the PID parameter is used to identify the process.
- "--cpu-list" is an option to specify the CPU or CPUs to assign to the process. "${cpu_id}" is a placeholder for the CPU or CPUs you want to assign, and it could be a comma-separated list or a range of CPUs.
- "${pid}" is a placeholder for the Process ID of the process you want to modify.
By executing this command with the appropriate values for "${cpu_id}" and "${pid}", you can control which CPU or CPUs the specified process can run on. This can be useful in situations where you want to optimize CPU usage or isolate a process to a specific set of CPUs.

never run a command you are not sure if it is safe.
