I hadn't noticed the paper (so thanks for the repost) but don't agree with
everything in the intro - specifically the point about RISC chip complexity
and power draw/heat output:

The transmeta chips are clearly low-consumption, low heat output chips (a
Good Thing), while P4, IA64 are hot, very hot (not so good). However, the
MIPS chips are nowhere near as hot as the Intel chips - see the recent
publicity about the 16cpu/4U compute brick for the SGI Origin 3900 ["The
R14000A only consumes 17 watts of power." -
http://slashdot.org/comments.pl?sid=44763&cid=4643891]. What's the position
with other RISC chips (HP, IBM)?

The other point I'm not happy about is the extrapolation from 9 months of
trouble-free operation to a zero downtime cost vs other options. Makes it
looks too much like they've decided what the answer should be and they're
working back from that to define the itemised costs. Perhaps I'm being
unfair but 9 months seems like a very small sample when compared to the data
that will have gone in to the other options.

However, it is very good to see this, as I've been interested in the TM
chips for a while, so seeing a paper about this sort of very high density
config is useful.

Hi,
Any body notice System Administration cost in table 5.
