CH/OTP Test Task
Instead of concentrating on speed, I decided to instead concentrate on a modular approach which (hopefully) guarantees correctness in a "perfect" network. If communication breaks down, no result will be reported.
The idea is to first implement a modular "broadcasting" layer on top of an arbitrary totally connected network of Cloud Haskell nodes - this abstraction is done in Distributed.Broadcast.
Using that abstraction, which provides totally ordered broadcasting on top of "normal" Cloud Haskell processes, it is relatively straight forward to implement the program.
I decided to accumulate results permanently (in constrast to ordering the messages later, during the waiting period). My reasoning for this design descision is that otherwise, it's difficult to run the algorithm for a long time without creating a space leak.
The program is started by running the shell script test.sh, which contains an example configuration of ten nodes on the local machine.
Unfortunately, I am not sure how to do this with different setup strategies.
