Abstract
Methods, apparatuses, and computer program products for performing collective operations on a hybrid distributed processing system that includes a plurality of compute nodes and a plurality of tasks, each task is assigned a unique rank, and each compute node is coupled for data communications by at least two different networking topologies. At least one of the two networking topologies is a tiered tree topology having a root task and at least two child tasks and the at least two child tasks are peers of one another in the same tier. Embodiments include for each task, sending at least a portion of data corresponding to the task to all child tasks of the task through the tree topology; and sending at least a portion of the data corresponding to the task to all peers of the task at the same tier in the tree topology through the second topology.
