Very nice. However, do you have any ideas what can be accomplished with a multi-computer rack infrastructure that costs about $500?

It is probably too weak to run virtualization (which racks are used for these days). It is also not trivial to set up cluster computing wherein these multiple computers can meaningfully share memory and computing resources. Many of us can afford a 7 computer rack for less than $500, but how do we use it?



Erlang (or Elixir) runs really well on the Pi - and cross-node communication is brain-dead simple.


Idea: each Pi could be placed in some carrying case (with power, external sensors, e.g. GPS), and individually taken out in the field.

Then, when the Pis are back home and networked together, they connect as a cluster and reconcile their individual data...
