maybe today I might be able to have an 8 or 10 core system, and maybe
tomorrow look at the economic and software possibility of having a 256 core
system. I figure that there would need to be some tight reins on latency,
and you would want some BIGTIME comm links, I dunno, maybe not be able to
use even Gigabit ethernet, maybe needing some sort of scsi bus linkage,
something on that scale? Or, is Fiber getting to that range yet?

Anyhow, is it even remotely posible for us to be able to strech our present
SMP software (even with it's limitation on word size to limit the range to
32 processors) to be able to jump across machines? That would be one hell
of a huge thing to consider, now wouldn't it?

Ahh, you're talking about parallel computing, "clustering", or "grid
computing". The Linux folks often refer to an implementation called
Beowulf:

I was also able to find these, more specific to the BSDs:

http://www.freebsd.org/advocacy/myths.html#clustering
http://lists.freebsd.org/pipermail/freebsd-cluster/2006-June/000292.html
http://people.freebsd.org/~brooks/papers/bsdcon2003/fbsdcluster/


Well, I am, and I'm not, if you could answer me one quiestion, then I would
probably know for sure. What is the difference between our SMP and the
general idea of clustering, as typified by Beowulf? I was under the
impression I was talking about seeing the possibility of moving the two
closer together, but maybe I'm confused in the meanings?
