Towards Tight Communication Lower Bounds for Distributed Optimisation

no code implementations NeurIPS 2021 Dan Alistarh, Janne H. Korhonen

We focus on the communication complexity of this problem: our main result provides the first fully unconditional bounds on total number of bits which need to be sent and received by the $N$ machines to solve this problem under point-to-point communication, within a given error-tolerance.

Improved Communication Lower Bounds for Distributed Optimisation

no code implementations28 Sep 2020 Janne H. Korhonen, Dan Alistarh

Motivated by the interest in communication-efficient methods for distributed machine learning, we consider the communication complexity of minimising a sum of $d$-dimensional functions $\sum_{i = 1}^N f_i (x)$, where each function $f_i$ is held by one of the $N$ different machines.
