I knew someone from the LOFAR project would react.
You guys very specifically were NOT targetted by my posting here.
You did do a brilliant job, as you can see in all the postings at different
dutch forums from me.
In fact you have built a machine in Netherlands for what was it, 6 million
euro, delivering roughly 27.5 tflop.
That's more than 2 times cheaper than the 2.2 tflop machine in Amsterdam,
which was serving users at 1 januari 2004.
btw now i have the chance to ask this:
I read a report somewhere that the total LOFAR budget was 150 million euro,
where do those other 144 million euro go to?
