Running the Server and Nodes

Starting the Server

The server is started by running the following command in the root directory of the framework:

python -m fed2tier.server.start_server

### Server Arguments

You can customize the server’s behavior using various arguments:

Argument	Description	Default
–algorithm	Algorithm to be used for aggregation by server	fedavg
–nodes	Number of nodes to be used	1
–s_rounds	Number of communication rounds to be executed by server	10
–n_rounds	Maximum number of communication rounds to be executed by nodes	10
–batch_size	Batch size to be used	10
–dataset	Dataset to be used	MNIST
–net	Network to be used	LeNet
–accept_conn	Determines if connections accepted after FL begins	1
–model_path	Specifies initial server model path	initial_model.pt
–resize_size	Specifies dataset resize dimension	32
–threshold	Specifies accuracy threshold for early stopping at each node	0.8

Starting the Nodes

The nodes are started by running the following command in the root directory of the framework:

python fed2tier.node.start_node

### Node Arguments

You can customize the node’s behavior using various arguments:

Argument	Description	Default
–device	Device to run the client on	cpu
–wait_time	Time to wait before sending the next request	5
–clients	Number of clients to run	10
–niid	niid or iid	1
–algorithm	Algorithm to run	fedavg
–epochs	Number of epochs	5
–mu	mu hyperparameter for fedprox	0.1
–rounds	Number of communication rounds	20
–carbon	If 1, track carbon emission of the node	0
