There's been a lot of raspberry pi clusters, heck there's been a few research papers on them and they all state the same thing: they're slow, they're not good value for money for this application and they don't work reliably enough to even use for a cluster configuration.

You can pick up dell laptops that are a few years old with i5 or i7 CPUs in them for £100 off ebay: one of those gives you more than 10 times the performance of a single raspberry pi, not to mention it can actually run a 64 bit OS, has an ethernet adapter faster than 100mbps and doesn't have a USB controller that is cringeworthy. Oh and it actually has a display.

I guess if he built it for the sake of just seeing if he could - it'd be OK.

But it sounds like, from his mannerisms/speech that he thinks he really "developed" something important.

If it was some guy who posted a vid - "hey I did this over the weekend - thought it was cool - so I recorded it - now Im gonna tear it down."
I would have said, "looks nice - well done.  What are you planning to do with all the diff controllers ?"

But this guy is all "in response for my dissertation..."  He's getting a PhD on how to waste time and build something irrelevant but has flashy lights.

Meh - Im just in a crappy mood.

I wonder what you can do with a cluster.

 

Is it a 'super computer' ?

 

Can you run a weather forecast, simulate a drug reaction, predict stock trades, etc. ?

 

Disappointing that he didn't show the cluster outputting something on a screen.

    • I wonder how driving laws around the world will change. No way to really tell if people are using phone. Same with smart watches i guess even now and those silly built in tablets for controlling the car instead of buttons.
