Hi Bharata,

I realise I'm a bit late on this, but I'm just catching up on the list
traffic.

Firstly why is the XML tag called "cell", it seems to represent what we
would normally call a "node" in terms of NUMA?

Also does the parser support disjoint ranges for cpus and memory? Or do
we not need that complexity for some reason?

For example what if I have a topology that looks like:

Node 0:
  CPUs: 0-3,8-11
  MEM : 0-1G,2G-3G

Node 1:
  CPUs: 4-7,12-15
  MEM : 1G-2G,3G-4G

cheers
