The idea behind it is that you string together a large number of CPU’s each with their own memory and connections to neighbouring transputers (using a series of ‘links’) into a computing fabric. A recent comment on HN suggested using a cpu-per-process as a means of achieving very high degrees of security. This made me wonder if you couldn’t use a Raspberry-Pi Compute Module to achieve this ...
