I do not pretend to have completely understood what Jim Keller is working on right now, but it looks like sending a bloc of operations to the processor managing that part of the data; that block of operation could be one "independant mill packet"...
Jim Keller system seems to be a very big array of Wormhole processor, itself described at the end of https://www.anandtech.com/show/16354/jim-keller-becomes-cto-at-tenstorrent-the-most-promising-architecture-out-there
