Distributed Extra-gradient with Optimal Complexity and Communication Guarantees
Ali Ramezani-Kebrya, Kimon Antonakopoulos, Igor Krawczuk +2
We consider monotone variational inequality (VI) problems in multi-GPU settings where multiple processors/workers/clients have access to local stochastic dual vectors. This setting…
