 - [ ] O1: Benchmark existing configurations and algorithms.
 - [x] O2: Separate the communication layer (topology) from collaborative learning algorithms.
 - [ ] O3: Implement a few more collaborative learning algorithms.
-- [ ] O4: Write the GRPC module for the communication layer. Then we don't need to rely on MPI which requires ssh access to all the nodes.
-- [ ] O5: Improve telemetry and logging for visualization of the network.
