elixir-pdx/distprime
#Overview
This exercise is designed to be an introduction to distributed Elixir programming. This is a partial revisitation of a previous problem we solved together, but with a few additional twists.
The challenge is to write a distributed prime number generator/finder. Such that you could request the Nth prime number and use multiple CPU cores and multiple computers to assist you in finding the answer.
We'll talk about strategies for how we might accomplish this before we begin.
Prerequisites:
#Getting Started
###Clone this repository.
$ cd ~/Repositories
$ git clone https://github.com/elixir-pdx/distprime.git
$ cd distprime
#Hacking
You may find it helpful to play with your code in Elixir's iex interactive console. If you want to do that and autoload the console session with your code then you can do the following from the project root:
$ iex -S mix
That will make sure that you're running iex inside your project's build environment.
#Building
To compile your project simply run this from the project root:
$ mix compile
#Testing
To run the test suite defined in test/distprime_test.exs then run this from the project root:
$ mix test
If you got your project bootstrapped correction you should see something like the following:
Called with 3
Called with 1
Called with 1000000
