taskset

taskset

The taskset command is a command-line utility that can be used to bind a process to a specific CPU core or set of CPU cores. It is a useful tool for performance tuning and for preventing processes from interfering with each other.

The taskset command is used as follows:

taskset [options] [pid] [cpu list]
  • options: These are optional flags that can be used to control the behavior of the taskset command.

  • pid: This is the process ID of the process that you want to bind to a specific CPU core or set of CPU cores.

  • cpu list: This is a list of CPU cores that you want to bind the process to.

For example, the following command will bind the process with PID 1234 to CPU core 0:

taskset -c 0 1234

The taskset command can be used to improve the performance of a process by binding it to a specific CPU core or set of CPU cores. It can also be used to prevent processes from interfering with each other by binding them to different CPU cores.

Here are some of the benefits of using taskset:

  • It can improve the performance of processes.

  • It can prevent processes from interfering with each other.

  • It is a simple and easy-to-use command.

  • It is supported by most Linux distributions.

  • It is available as a free and open-source software.

Here are some of the drawbacks of using taskset:

  • It can be difficult to use to bind processes to specific CPU cores if you are not familiar with the Linux kernel.

  • It can be difficult to troubleshoot if there are problems with the taskset command.

  • It may not be as effective as some other methods of performance tuning or process isolation.

Usage: taskset [options] [mask | cpu-list] [pid|cmd [args...]]


Show or change the CPU affinity of a process.

Options:
 -a, --all-tasks         operate on all the tasks (threads) for a given pid
 -p, --pid               operate on existing given pid
 -c, --cpu-list          display and specify cpus in list format
 -h, --help              display this help
 -V, --version           display version
