Re: Starting a process on the specific CPU.

[jd <d.javed@free.fr>]

you have :

int sched_setaffinity(pid_t pid, unsigned int len,
			unsigned long * user_mask_ptr)

int sched_getaffinity(pid_t pid, unsigned int len,
                             unsigned long * user_mask_ptr)

to bind a process to a specific (or a group) CPU : with a mask.

you can find a package (schedutils) to manipulate that on robert love's 
homepage :
