POSIX threads policy and priority

Hi!

I am using posix threads in my application. I am explicitly setting the priorities and the scheduling policy. POSIX threads support 3 types of scheduling - FIFO, RR and OTHER. My second thread needs most of the CPU cycles. Can anybody please clarify what the scenario will be if I use FIFO or RR for my threads but assign different priorities to them? How can I give my second thread the greater part of the CPU cycles?

Thanks and regards,

Arun

What have you managed to figure out from reading the manual?

Hi Salem,

Thanks for taking interest. What I need to know specifically is does Linux 2.4 manage threads with different priorities but same scheduling policy in the same task list? What is the outcome if two threads have different priorities and also different policies? Is it possible to use two different different scheduling policies for two distinct threads? My main() which spawns the two threads returns just after spawning by calling pthread_exit(); Please help.

Regards,

Arun
