I saw a story a while back about a guy who made a clustered supercomputer with raspberry pis, and saw that the hardware organisers had like 60+ unused RasPis that I could use to make a supercomputer.
What it does
There is a master RasPi that controls everything and a bunch of slaves that do the actual processing grunt work. The master will accept some data and a function that processes the data and then tells the slave to process each datum, receives the computed results, and returns the results.
How I built it
I threw together some Node.js
Challenges I ran into
The raspberry pis kept breaking. Constantly
Accomplishments that I'm proud of
I made software that can be deployed to make a cloud
What I learned
The Raspberry Pis are not reliable at all.
What's next for NodeNodeJS
Add dozens of RasPis to increase the processing power.
