I have a Decoding video C program and want to split it into 4 independent blocks and want each block to run thread on different CPU CORE (have 4 cores)
I am facing troubles in allocating each thread to its corresponding CPU that i chose
i have found library <sched.h> that contains fct sched_getcpu() that returns the cpu numbers that is running but i cannot know my desirable fct
any one could help??
i just need to know the fct that could help me
thanks

i have read about openMP its problem that threads are distributed on cores randomly, i want static scheduling the key i found was in the <sched.h> library and the fct was sched_affinity(parameters);
i think this is better way for parallelizing1!!

Do you have real-time constraints on you program? That is probably the only time static scheduling might be beneficial, i.e, worth the trouble.
