Binding process to a fixed processor

[Dennis George]

Actually I am looking for some command or system call which I can execute from my user level program so that I can bind one of my process to a processor............. like pbind command in Linux..............
 
Or do I have to write a system call to do that ??????????

You can bind a thread to one processor, in the kernel, but I don't know
offhand if there is a user interface for it however.. (I'd have to go
look at the code again). (goes to look)

There is code that can bind a thread to the current processor that it is on,
but nothing uses it that I can see.. If you wrote a kernel module you could 
write your own syscall to use it..


This is of course different from binding a thread to a processor
EXCLUSIVELY so that no other thread can use it.
