DeepFlex

Distributed DNN training simulator.

Simulation Methods

Note: all methods insert an event at the current time step if no time is specified.

• now() - return current simulation timestep
• print_actors() - print a list of current actors in the simulation
• run() - begin simulation loop
• create_server(s_params, t) - instantiate a server at time t
• create_client(c_params, t) - instantiate a client at time t
• online_client(c_id, t) - bring client online at time t
• offline_client(c_id, t) - take client offline at time t
• assign_client_to_server(c_id, s_id, t) - assign client c_id to server s_id at time t

Events with configurable timings include:

• Server.aggregation_time - time for server to receive update from client
• Server.model_send_time - time to send global model from server to client
• Server.update_time - Server model update time
• Client.aggregation_retry_time - Aggregation retry delay
• Config.training_time - Client training time
