I've been looking at the processor requirements for a fairly large research
signal processing job (say 0.5 TeraFLOP usable so probably 3 TFLOP
'theoretical') and wondered if anyone could point me to appropriate news
groups or web resources.

I'm considering the likes of Mercury and Sky (Altivecs) and I'm also keen on
understanding what the PC Blade market has to offer since this appears to
offer advantages in certain areas. (Power/CPU density isn't such a driving
force as it might be in a production environment).

There seem to be the lower power options and high end products (e.g.
Opteron, Itanium2, Power4)

Chief areas of concern:

Supporting high data rates (100+ MB/s per channel) e.g. Infiniband, RapidIO,
serial FPDP, Myrinet etc.

Understanding OS (or just a kernel) choice. - Don't particularly need
multi-threading (can cause some real miserable cache flushes )

Evaluating (particularly in the PC market) well respected vector processing
libraries, optimising compilers etc. - Also discussions on PVM, MPI, Signa
processing libs etc. Holy grail is a system that runs on a single
workstation/PC or a parallel 'farm'.

High speed comms - I know many of the options available, but want to hear
user experiences e.g. the university supercomputer projects etc.

I really want to avoid reinventing many wheels or dying a death at the
bleeding edge.

I know this isn't the place typically for these discussions though it does
get touched upon sometimes so pointers would be appreciated.
(This group has helped with high availability discussions, I2C etc.)

Followed the FAQs, comp.dsp and several other useful starting points, but I
usually hit a wall when it comes to discussing the use of recent advances -
possibly just due to commercial sensitivities. However supplier 'figures'
and descriptions don't always tell the whole truth without a great deal of
digging and evaluation phases.

www.cotsjournalonline.com has had some useful info in the past, but you
can't beat user experiences to learn shortcomings quickly.

Would try news:comp.dsp if I was U :-)

Why? Do they have special knowledge about 1 ohm resistors in that
newsgroup? ;-)

No no ... but informations on how to perform 16-by-16 FFT on it ;-))
