Hi,
Is it possible to run two xenomai user space real time tasks in parallel
on say two different cores(assuming the threads are not contending for same
memory resources at the same time)?? I have tried giving two real time
tasks equal priorities of 99 and using T_CPU to bind them to different cores
.Is this enough???
Does T_CPU(x) guarantee that my task will be run always on CPU x or does it
just increase the chances of running on CPU x??
How do i know which core my real time task is running ??Is some tool
available for real time monitoring of threads and the cores they are running
on ??
Thanks in advance.
With Regards,
S Saravanan

Do you have any specific problem, for which you would need some help?
Something does not work as expected?
