Re: A small query
Neither is overall "better". Please read a (good) book about
supercomputers and understand the way individual specs mean little. There
is no such thing as the "fastest" supercomputer. Fastest at what? It
takes alot of simulation and study and even experiments to figure out
which system will run your particular program the fastest.
Assuming similar technology...
about a 1/4 gig of RAM, about a gig/sec of memory bandwidth, and about 1/4
gig/sec of hard drive bandwidth
Three plan (assuming 128Meg, in the long run its being too much of a
cheapskate to buy the 64Meg)
about 1/3 gig of RAM, about a 1/3 gig/sec of memory bandwidth, and about
1/10 gig/sec of hard drive bandwidth
The Three plan will do medium size, sequential computations (where
everything is kept in memory) slightly faster than the Eight.
The Eight plan will utterly whip the three plan in random access of huge
data files and random memory access if programmed correctly.
What you didn't specify was the network infrastructure. Wirespeed
switched gig ethernet will perform dramatically different than "all the
machines on one 10-base-2 coax segment)
Also don't know the on chip cache specs. I would guess the eight plan
would have more on chip cache?

I think more memory will be useful according to my intuition.
