What are some tools for managing CPU affinity in Linux?

There are several tools you can use to manage CPU affinity in Linux, such as 'taskset', 'cgroups', and 'htop'. Would you like to know how to use any of these?

Yes, can you explain how to use 'taskset'?

Sure! 'taskset' is a command-line utility that allows you to set or retrieve the CPU affinity of a running process. You can use it like this: taskset [mask] [command]. The mask is a hexadecimal representation of the CPUs you want to assign.

What does the mask look like for a dual-core CPU?

For a dual-core CPU, the mask would be '3' (binary '11'), which means both cores are selected. So, you would use taskset 0x3 [command].

Are there any graphical tools for this?

Yes, 'htop' is a great graphical tool that allows you to manage CPU affinity easily. You can select a process and press 'F affinity' to set its CPU affinity.
