FedMed Flower SuperLink

This repo contains the complete ChRIS plugin that launches the Flower SuperLink for the FedMed demo. Run the commands below from inside plugins/superlink_plugin/. The SuperLink coordinates training, waits for a configurable number of Flower SuperNodes to connect over gRPC, and writes a JSON summary of the run and the weights file to /outgoing.

Build

docker build -t fedmed/pl-superlink .

Run (example)

docker run --rm --name fedmed-superlink --network fedmed-net \
  -v $(pwd)/demo/server-in:/incoming:ro \
  -v $(pwd)/demo/server-out:/outgoing:rw \
  fedmed/pl-superlink \
    fedmed-pl-superlink \
      --rounds 3 \
      --total-clients 3 \
      --local-epochs 10 \
      --learning-rate 0.2 \
      --data-seed 13 \
      --fraction-evaluate 1.0 \
      /incoming /outgoing

Use docker inspect fedmed-superlink to obtain the IPv4 address and pass it to SuperNode containers (Flower prefers literal addresses on Docker networks).
