Guys, this is not rocket science. All of these references are to
a network node.

For IRC, the network is the Internet.

For a cluster, the network is ethernet or IB or whatever.

In the Linux NUMA kernel example, the network is HyperTransport or QPI
or NUMAlink.

If someone uses "nodes" when talking about a Linux cluster, the
meaning is pretty clear, even if the boxes are NUMA.
