一种方法是通过改变cpu亲和性，绑定运行中的线程

[coolpi@localhost ~]$ taskset -h

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

The default behavior is to run a new command:

taskset 03 sshd -b 1024

You can retrieve the mask of an existing task:

taskset -p 700

Or set it:

taskset -p 03 700

List format uses a comma-separated list instead of a mask:

taskset -pc 0,3,7-11 700

Ranges in list format can take a stride argument:

e.g. 0-31:2 is equivalent to mask 0x55555555

For more details see taskset(1).
