Systems, apparatuses, and methods for managing cluster-level performance variability without a centralized controller are described. Each node of a multi-node cluster tracks a maximum and minimum progress across the plurality of nodes for a workload executed by the cluster. Each node also tracks its local progress on its current task. Each node also utilizes a comparison of the local progress to reported maximum and minimum progress across the cluster to identify a critical, or slow, node and whether to increase or reduce an amount of power allocated to the node. The nodes append information about the maximum and minimum progress to messages sent to other nodes to report their knowledge of maximum and minimum progress with other nodes. A node updates its local information if the node receives a message from another node with more up-to-date information about the state of progress across the cluster.
