Nodes of a computing cluster can be selected to run new computing jobs while providing acceptable performance of jobs running on the nodes. Respective performance metrics of respective workloads on respective computing nodes can be determined. Each workload can include a new computing job and the performance metrics can be determined based at least in part on respective measured performance data of the ones of the computing nodes and information of the new computing job. Candidate ones of the computing nodes can be determined based at least in part on the respective performance metrics. One of the candidate computing nodes can be selected based at least in part on the information of the new computing job. In some examples, identification of the new computing job can be transmitted to the selected node. In some examples, state data of the nodes can be updated based on the performance data.
