    It must be fun when you can spend 3000$ for fun.

    I appreciate you featuring my project here!

    Regarding other comments, the processor on the Pi is approximately 20 to 40 times the speed of a 486DX2-50, depending on your metric. The cluster I built should be should be similar in performance to the Origin2000 systems from the late 1990s, but with slower interconnects. Applications that don't rely on having such fast interconnects should work just fine.

    I wanted to point out that, with different cards, my case design could be used with other similar boards, such as the Beaglebone Black. It might be slightly harder to set it up with Gigabit Ethernet switches, due to most 24-port Gigabit switches being too wide), but I think that should become practical in the future. This would alleviate the bottlenecking issue mentioned in the article.

    And yes, part of the purpose of this project has been the fun side of it. I also also think it will be a lot more interesting to run distributed code on a hardware platform, where I can see lights blinking and such as it works. But I grew up on movies that had supercomputers with huge panels of blinking lights, so I suppose that sentiment may not be universal.

    Well, sure, but a 486 won't be able to do a whole lot of concurrent operations. That's like comparing a CPU to a GPU--they're different beasts, with different purposes.

    That said, he was doing it sort-of for fun, but it started out as a thesis project. According to his blog post, he's going to use it to test distributed software.
