Abstract: A device includes a communication scheduler to generate schedule trees for scheduling data communication among a plurality of nodes configured to perform a collective operation using data contributed from the plurality of nodes. The device includes data reduction logic to: identify one or more skewed nodes among the plurality of nodes, perform, according to a first set of schedule trees, a first operation to generate partial results based on data contributed from non-skewed nodes, and perform, according to a second set of schedule trees, a second operation to generate final results based on the partial results and data contributed from the one or more skewed nodes.
