Hi there
I am trying to perform some timing test using rtl 2.0 and an SMP system.
I have 4 threads each running at different rates (1,2,4,8 khz), they all
have the same priority. For now I
am putting all threads on the same CPU.
Is there a way of knowing when the slow threads are interrupted ? I have
an idea of using gethrtime() at the beginning and exit of each threads and
analyze these times to see how things get called and interrupted.
any suggestions ?
how is the scheduler work in such a situation ? does it allow the fastest
thread to interrupt the slower threads ? I have balanced the load to
ensure that I have enough CPU time to execute them all in one of their
cycles but I would like to confirm that somehow.
Thank you
Michel
