Re: How can we bound one CPU to one Gigabit NIC?

Thanks Ben. We are going to use SysKonnect Cards. Are they tg3 based, too?
Thank you.

Hi Everyone,
      I am now doing some experiments on Dual CPU (2.4Ghz) with 2

cards. Can anyone tell me how to bound one CPU to each NIC so that we

need to care about the packet-reordering and the interrupt sharing

problems?

      Thank you very much.:)

My experiments show you will still get re-ordered packets occasionally
(but then again, I'm having other wierd problems, so maybe you wont).

# Bind processor 2 (1<<1) to irq 11
echo 2 > /proc/irq/11/smp_affinity

# Bind processor 1 (1<<0) to irq 19

I will be interested to hear of your results, as I have been having
heating problems with e1000 and other problems with tg3 based nics!
