In the discussion of "X and NeWS History", I mentioned "PIX", which integrated PostScript with tuple spaces on Transputers, in thread about how X-Windows is actually just a terribly designed and implemented distributed database with occasional visual side effects and pervasive race conditions:
Jon Steinhart: "Had he done some real design work and looked at what others were doing he might have realized that at its core, X was a distributed database system in which operations on some of the databases have visual side-effects. I forget the exact number, but X includes around 20 different databases: atoms, properties, contexts, selections, keymaps, etc. each with their own set of API calls. As a result, the X API is wide and shallow like the Mac, and full of interesting race conditions to boot. The whole thing could have been done with less than a dozen API calls."
To that end, one of the weirder and cooler re-implementations of NeWS was Cogent's PIX for transputers. It was basically a NeWS-like multiprocessing PostScript interpreter for Transputers, with Linda "tuple spaces" as an interprocess communication primitive:
The Cogent Research XTM is a desktop parallel computer based on the INMOS T800 transputer. Designed to expand from two to several hundred processors, the XTM provides a transparent distributed computing environment both within a single workstation and among a collection of workstations. Using Linda tuple spaces as the basis for interprocess communication and synchronization, a Unix-compatible, server-based OS was constructed. A graphic user interface is provided by an interactive PostScript window server called PIX. All processors see the same set of system services, and within protection limits, programs capable of using many processors can spread out over a network of workstations and resource servers, acquiring the services of unused processors.
Another good article to read about this is "Linda Meets Unix", which was published in IEEE Computer magazine. https://ieeexplore.ieee.org/document/44903/ (full disclosure: I wrote it).
