Flame is a platform that enables developers to compose and deploy federated learning (FL) training workloads easily. The system is comprised of a service (control plane) and a python library (data plane). The service manages machine learning workloads, while the python library facilitates composition of ML workloads. And the library is also responsible for executing FL workloads. With extensibility of its library, Flame can support various experimentations and use cases.
We have improved Flame with a redesigned control plane and data plane (called LIFL) for efficient FL aggregation at scale. LIFL leverages shared memory processing to achieve high-performance communication for hierarchical aggregation. We also introduce locality-aware placement in LIFL to maximize the benefits of shared memory processing. LIFL precisely scales and carefully reuses the resources for hierarchical aggregation to achieve the highest degree of parallelism while minimizing the aggregation time and resource consumption.
The target runtime environment is Linux. Development has been mainly conducted under macOS environment. One should first set up a development environment. For more details, refer to here.
