Hi Thomas,
I just compiled the kernel with the patch on my whole cluster
of 6 fedora10 and the results are very stable and smooth.
Thanks for the report !
you're welcome ! :D
the only little thing is the cluster software heartbeat / pacemaker
takes 20% of cpu that 11% before on a dual xeon nocona with
linux command "top".
That might be related to the new mechanism how we handle softirqs. If
the heartbeat/pacemaker app is using networking a lot then this might
explain it.
Thanks,
tglx
yes it uses constantly the network (1GB hub between the nodes)
for high availability.
Thanks for the explaination
