This is still using original Series Bs... which are essentially obsolete by now. I stopped using them around 2 years ago: https://github.com/rcarmo/raspi-cluster Using Pi 3 boards would quadruple the number of cores and yield a 600% increase in thanks to the slightly faster default clock rate...

Re: Tiny Titan
#13More descriptive title, e.g. ‘Tiny Titan, a $1,000 classroom supercomputer’ would be helpful.
How does this cost $1,000? The budget is clearly not being used efficiently. The only computing part, the 9 RPi's are 315$ all together. So what, 685$ of plastic and accessories. Hmm....

#14Earlier quoted context omitted.
They're not actually trying to build a high-powered computing cluster, just demonstrate how one works.
Neither of them is really high-powered, believe me. :) But using one with old B boards could be excruciatingly slow at times, which is why I just had to upgrade mine - it’s since become a lot more productive in the sense that my tests take around 5 minutes instead of a whole hour :)

Re: Tiny Titan
#16Why not just use virtual machines to sub out the RPis? Without the curriculum, it's not clear what they're trying to teach here. Assembly? Networking? Administration of the RPis?
the fact that it looks really cool likely has surprisingly strong effects on student motivation and work/attention levels, leading to more learning, which is the sole target here
Do we assume that 18+ folks are only interested in parallel programming if it's assembled of shiny pipes?

This. The first step to teaching anyone anything is to grab their attention. Especially kids/teens.
But I'll admit, the price is too steep. They can definitely do better

30 bucks per USB LED Light, 15 bucks per USB cable... they don't choose cheap components.
If your parts are more expensive than the rPI itself, you're not going to need it. Those cases aren't cheap either.

We had an overpriced external hard drive we had to slot into computers to play around with, but it helped because it wasn't a virtual "imaginary" thing.

Or make it so you can plug in any Pi, is there anything of a secondhand market for those yet? I can imagine there isn't though, those things are cheap enough to be throwaway / lose in a drawer devices.
