The Transputer is a very cool idea -- a moderately powerful yet inexpensive CPU with dedicated communications devices on chip. You connect many of these together to form a huge parallel system. If you really want massively parallel a Transputer is the way to go. Unfortunately, INMOS spent too much time on the latest and greatest Transputer, and it died off for lack of consumption. This is a great loss, for the idea is sound.
At one point in time Atari (yes Atari) made a Transputer workstation, using a Atari ST in a compact board format running as a front end to a expandable set of Transputers. It also had some high end Atari graphics system to run any output on. Way cool -- Transputer for the desktop -- but it fizzled too.
Floating point math has a distinct tie-in between hardware and software support. While some of this is software, it replicates what most FP chips implement.
I need to track down some info on PDP-11, VAX, and IBM-370 floating point formats. Each of the formats has its own benefits and downsides.
The Marquis De Sade said it all...
Oh, what action as voluptuous as destruction!
There is no Esctasy like the one we taste --
When we give ourselves over to this divine infamy!"
