newbie SMP questions
Hello everybody -
Given a chance to play with an SMP (dual AXP) machine, and having no
prior SMP experience, I've got a couple questions:
1. Are CPU shared at a timeslice level or at a program level? Ie. can
a program migrate from one CPU to another one or it'd stick to one
CPU?
2. Is the SMP support completely hidden from a user or it allows
starting a program on a certain CPU? In particular, I have a fairly
numerically-intensive program which I used to run in one instance
on a machine. Now I'd like to take advantage of the 2nd CPU to
start another instance of the program, but I need to make sure they
don't share same CPU.
3. What pointers to further SMP information could you recommend? NOTE,
I did read the {SMP,smp}* files in the Documentation directory of
the kernel and they are not very helpful.
Thanks in advance,
