In-network compute operation spreading

A networking method, comprising:

• receiving vectors from endpoint devices as part of an aggregation and reduction process;
• performing elementwise and vector splitting operations with the received vectors as input yielding at least two intermediate vector results, including a first intermediate vector result and a second intermediate vector result;
• sending the at least two intermediate vector results to different corresponding network switches in different switch aggregation trees including sending the first intermediate vector result to a first network switch in a first switch aggregation tree and the second intermediate vector result to a second network switch in a second switch aggregation tree;
• receiving at least two final vector results of the aggregation and reduction process from the different switch aggregation trees including receiving a first final vector result from the first network switch and a second final vector result from the second network switch;
• combining the at least two final vector results to yield a combined final vector result;
• and
• sending the combined final vector result to the endpoint devices.

A system, comprising a plurality of network switches including different switch aggregation trees of the network switches having a leaf layer of the network switches, wherein:

• each of the network switches in the leaf layer is to:
• receive vectors from respective endpoint devices as part of an aggregation and reduction process;
• perform elementwise and vector splitting operations with the received vectors as input yielding intermediate vector results;
• and
• send different ones of the intermediate vector results to the network switches in the different switch aggregation trees;
• the network switches in the different switch aggregation trees are to perform at least part of the aggregation and reduction process yielding different final vector results and provide the different final vector results to the network switches in the leaf layer;
• and
• each of the network switches in the leaf layer is to:
• receive the different final vector results from the different switch aggregation trees;
• combine the different final vector results to yield a combined final vector result;
• and
• send the combined final vector result to the respective endpoint devices.
