taskset (util-linux-ng 2.17.2)
usage: taskset [options] [mask | cpu-list] [pid | cmd [args...]]
set or get the affinity of a process
  -p, --pid                  operate on existing given pid
  -c, --cpu-list             display and specify cpus in list format
  -h, --help                 display this help
  -V, --version              output version information
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

例：

將pid號為2181的進程綁定到cpu0上：

[[email protected] ~]# taskset -cp 0 2181
pid 2181‘s current affinity list: 0
pid 2181‘s new affinity list: 0

將pid號為2181的進程綁定到幾個cpu上:

[[email protected] ~]# taskset -cp 0,1 2181  --綁定到cpu0和cpu1上

利用taskset命令，將某進程綁定到某個CPU上
