We show that any randomised Monte Carlo distributed algorithm for the Lovász local lemma requires Ω(log log n) communication rounds, assuming that it finds a correct assignment with high probability. Our result holds even in the special case of d ∈ O(1), where d is the maximum degree of the dependency graph. By prior work, there are distributed algorithms for the Lovász local lemma with a running time of O(logn) rounds in bounded-degree graphs, and the best lower bound before our work was Ω(log^∗ n) rounds [Chung et al. 2014].
