[Beowulf] Intel quad core nodes?

[andrew holway]

I was asking a similar question a couple of weeks ago and was unable
to get a definite answer.

I mostly gathered that amd's decision to build quad core from scratch
rather than just bolt two duals together has meant that Barcelona is
basically a bit naff. Lots of innovative stuff in there but not quite
working properly yet.

The benchmark boys that test these things have said that harpertown is
worth the wait but I would imagine not as interesting Q2 2008 when AMD
lick barcelona into something sexy.

I have heard Q4 2008 will bring 32 & 64 core chips. :)
