The present disclosure relates to minimizing the execution time of compute workloads in a distributed computing system. An example method generally includes receiving, from each of a plurality of server clusters, an estimated completion time and cost information predicted to be consumed in processing the compute workload. A workload manager compares the received estimates to a completion time and threshold cost criteria. Upon determining that the estimated completion time and cost information from any of the plurality of server clusters does not satisfy the completion time and threshold cost criteria, the workload manager partitions the compute workload into a plurality of segments, requests estimated completion time and cost information from the plurality of server clusters for each of the plurality of segments, and selects a cluster to process each segment of the compute workload based on the estimated completion time and cost reported for each segment.
