Methods, compute nodes, and computer program products are provided for DMA engine assisted local reduction. Embodiments include receiving, by a DMA engine, one or more data descriptors, each descriptor identifying a buffer containing an array for reduction; selecting, in dependence upon the arrays in the buffers and local hardware functional units available to the DMA engine, at least one local hardware functional unit; and reducing one or more arrays in the buffers identified by the data descriptors with the selected local hardware functional unit.
