And the SYSTEM is very expensive. I suspect that it is not more
cost-effective than a commodity cluster, despite being built with $10
cpus.

That is an area of active interest in the military and other areas:
boards plugged into a general purpose system. Deep Thought was built
that way. But ease-of-use, pricing, and keeping up with technology
trends have always been problems. The issues are the same as with
"attached processors" or "array processors" from the 1960's and
1970's.
