Subject: How can I migrate a currently running task?

Hi,

       I am working on Intel Duo Core with Linux OS 2.6.21, and I'd  
like to migrate task from one cpu to another cpu.
In SMP systems, load_balance() function uses move_tasks() to move  
processes from source runqueue to local runqueue, but it does not move  
a currently running task. If I want to migrate a currently running  
task from source runqueue to local runqueue, how can I do? Any  
suggestion is preferred. Thanks!

     Liang
