More 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....
A useful tool for explaining the basic concepts in a tangible way.
Earlier quoted context omitted.
30 bucks per USB LED Light, 15 bucks per USB cable... they don't choose cheap components.
Yeah they could save a bunch on those; the USB LEDs are things they could make themselves, stick them into the gpio pins. Actually they don't need those. If your parts are more expensive than the rPI itself, you're not going to need it. Those cases aren't cheap either.
Considering it's sat in front of a Titan super computer, it was probably easy to get the thousand dollar budget considering how much went into the box behind it :P
It's less costly, and all of the concepts are the same (except for connecting them using cables, but that's only a plus if you like the physical experience over abstraction, in which case perhaps computing is not really your thing to start with).

(joking) gotta get that rgb man
I'm thinking about building one, but with Pi Zero's and USB networking. The ClusterHAT guy wrote software to netboot the nodes off a cluster controller's SD through the USB network. With that, you don't even need an SDcard for each node. I was thinking about also adding a LED bar with one LED for each GPU SIMD element, refreshing a couple times per second and lighting up for the units used above a certain threshold.…
neat stuff, i didn't know that, going to read up.
Why not just simulate the computer on a single desktop PC using a bunch of virtual machines? It's less costly, and all of the concepts are the same (except for connecting them using cables, but that's only a plus if you like the physical experience over abstraction, in which case perhaps computing is not really your thing to start with).

The answer is right there at the top of the article: that it's for the classroom.
