Hi all: Lets say i have an SMP machine with 4 processor running Linux 2.6, and i have 6 instances of an RT critical processes If I set the smp process affinity of those 6 processes to the first 3 processors (two for each processor), run them as an RT processes with FIFO sched policy, and left the forth processor to handle other non-critical tasks in short if i do: #taskset 0x01 chrt -f 50 critical_program & #taskset 0x01 chrt -f 50 critical_program & #taskset 0x02 chrt -f 50 critical_program & #taskset 0x02 chrt -f 50 critical_program & #taskset 0x04 chrt -f 50 critical_program & #taskset 0x04 chrt -f 50 critical_program & As i've read that Linux will balance the length of run queue of all processors, but here i have three processors that are not going to handle any process the question is: do i have to manually set the smp affinity of all other non-critical tasks to the forth processor or Linux will do this automatically ?
