Yes it is very interesting.
However their sales price of $100k they initially quoted i found a bit
I don't want to be rude, but these processors are quite slow if you just
look to 1 processor and they go back in performance after a while when they
So a fully loaded system will have a far smaller performance in the long
run than it has in the short run.
Of course that has its charm too, a system that's fast if you just use it
real short at a "critical" moment.
So the quoted performance is still impressive then.
The network is not so impressive what each node is connected to another
node. That is not relevant for embarrassingly parallel software though.
Relevant is the price per gflop IMHO.
For a NEW product that tries to fight itself into the market, you must
simply be factors cheaper than the competition. $100k i find a tad expensive.
So to speak you can buy 10 quad dual core opterons 1.8Ghz for that price.
that's 80 processors x 3.6 gflop = 300 gflop too.
So effectively 10 quad opterons are faster in floating point than this
It's true however that the 10 quads eat a bigger power bill.
But if you can afford paying $100k that won't be a problem either.
And this said, i do not feel the opteron is a good floating point
processor. I would instead say it sucks ass for floating point. So if it
outperforms a floating point solution in dollar per gflop, then there is
something wrong with the system in question.
So real interesting is knowing the price it gets sold for now. If it gets
sold for $10k for 150+ gflops, then that is a good buy IMHO.
Nevertheless if we consider the fact that this company just starts to make
clustered systems and already so quickly puts such an impressive product in
the market they sure have my compliments.
IMHO they are the right type of company to make a clustered cell type
processor system (if ibm wants to deliver them cpu's). Their system needs a
fast processor that uses little power. The philosophy i really like.
Please note it would perform horrible for my own software, as it is latency
sensitive software, so anything i write down here is meant for software
other than my searching software.
