Re: [Xen-devel] MPI benchmark performance gap between native linux anddo
Mark,
Thanks for the advice. I will explicitly specify "cpu" option in domU's config
file.
So far, I think my experiments are not affected by this. In my experiments, I only run at most 1
domU besides dom0. I think the domU will be assigned to 2nd CPU even the assignment policy is round
robin.

I think I said something wrong here. If I do not specify "cpu" option in
Xen config file, I observe Xen usually assigns the 2nd CPU to domU while
running dom0 on the 1st CPU.
Last time I looked, the default was to assign in a round robin fashion. i.e.
the next domain you create will be on the 1st CPU (with dom0) unless you
explicitly specify otherwise - watch out this doesn't confuse your testing.
Cheers,
Mark
