Vivaldi

Prototyping and visualizing the Vivaldi algorithm in Elixir.

---

Test it for yourself!

1. Clone the repo

git clone [email protected]:pixyj/vivaldi.git

2. cd to the vivaldi directory

cd vivaldi

3. Fetch dependencies

mix deps.get

4. Run tests

epmd -daemon
mix test

5. Build the vivaldi binary

mix escript.build

6. Copy the binary to a bunch of servers

7.On each peer,

7.1 Install Erlang

7.2 Start the epmd daemon

epmd -daemon

7.3 Start the peer.

(Assign a unique node_id to each peer)

  ./vivaldi --nodeid <node_id> --nodename <node_id>@<node_ip_address> --cookie <cookie>

8. Start the algorithm using the controller.

You can run the controller on your local machine using iex

8.1 Start iex

iex -S mix

8.2. List all peers

peers = [
  "<peer_ip_address_1>",
  "<peer_ip_address_2",
  # And so on
]

8.3 Start the controller node

alias Vivaldi.Experiment.Controller

cookie = :<cookie>
ip_address = "<ip_address>"

Controller.start :"controller@#{ip_address}", cookie, peers

And we're done! Let the algorithm run for a few minutes.

9. Collect Results

Controller.visualize()

A file call my_events.json will be placed in the visualization directory.

10. Visualize!

Follow instructions at the visualization directory.
