Add to ORKGThis paper considers the k-set agreement problem in a synchronous distributed system model with send-omission failures in which at most f processes can fail by send-omission. We show that, in a system of n +1 processes (n +1>f), no algorithm can solve k-set agreement in rounds. Our lower bound proof uses topological techniques to characterize subsets of executions of our model. The characterization has a surprisingly regular structure which leads to a simple and succinct proof. We also show that the lower bound is tight by exhibiting a new algorithm that solves k-set agreement in + 1 rounds
