According to NCUBE glossies in front of me: "512 billion bytes of memory capacity" So up to 64 Mbytes/processor.. about price: "... at less than $1000/MFLOP and $1000/Mbyte" and elsewhere: ".. varying number of processors - from 16 to 8192 - that deliver from 8 to 27,000 scalar MFLOPS" (So, price can be deduced.. But I believe it will be highly non-linear..) On another point: Yes it is more difficult (but not too difficult) to program distributed memory machines. But the rewards are great, and the challenge is stimulating. I believe they will be useful for a large fraction of applications. When people claim that "they are good for some applications, but not most", they sometimes may mean a particular algorithm or a particular way of doing things may be difficult on message passing machines. But not the end application - it can often be reformulated so it works fine on them.
