1. A method for reducing network data traffic when operating a memory system of a machine comprising: a first node coupled to a second node by a network, the first node comprising: a first main processor, a first network interface, a first active buffered memory device including a first processing element and a first memory vault comprising a first stack of memory devices, and a first local interconnect network providing a first data movement path between the first network interface, the first main processor, the first processing element, and the first stack of memory devices, wherein the first processing element and the first memory vault are coupled to the first local interconnect network within the first node, and the second node comprising: a second main processor, a second network interface, a second active buffered memory device including a second processing element and a second memory vault comprising a second stack of memory devices, and a second local interconnect network providing a second data movement path between the second network interface, the second main processor, the second processing element, and the second stack of memory devices, wherein the second processing element and the second memory vault are coupled to the second local interconnect network within the second node, the method comprising: receiving a processing instruction at the second node; determining, by the second node, that the processing instruction includes an operation utilizing data stored locally at the first node, wherein said data was already stored in the first stack of memory devices at the first node prior to receipt of the processing instruction at the second node; transmitting a remote transaction message from the second node to the first node across the second local interconnect network through the second network interface across the network to the first network interface, the remote transaction message identifying the operation and the data already stored locally at the first node to be utilized in the operation to push execution of the operation from the second node to the first processing element of the first node; receiving the remote transaction message from the second node in the first processing element in the first node via the first network interface and the first local interconnect network while bypassing the first main processor on the first node; accessing, by the first processing element in the first node, the data to be utilized in the operation identified in the remote transaction message from a location in the first stack of memory devices in the first node; performing, by the first processing element in the first node, the operation identified in the remote transaction message utilizing the locally stored data identified in the remote transaction message to obtain an operation result; updating, by the first processing element in the first node, the locally stored data in the first stack of memory devices based on the operation result; and transmitting the operation result from the first node to the second node in response to performing the operation identified in the remote transaction message.
