It looked like it did IEEE754 doubles. Any Intel types out there

what I don't really understand is why there aren't lots of groups doing
this kind of exploratory chip. is it just that any interesting chip
tends to push design, circuit and fab boundaries all at the same time?

frankly, I'm a bit embarassed by all these experts being quoted as saying
that multicore is the brave new world.
Wouldn't Illiac IV be an example of multicore? (albeit SIMD, and I
assume the terascale doesn't require all cores to do same ops in lockstep)
Maybe CM would be a better early example?
I saw one article that claimed that no OS existed to utilize 80
threads, and that no programmers could use them.
Jeeze.. pop up task manager in my desktop machine running WinXP, and
there's gotta be at least 100 threads.. granted, some are blocked for
I/O or timers, or not doing a whole lot
(counterexample: Altix running Linux and OpenMP code from pretty mundane
programmers...)
amdahl's law: not just a good idea...
