1. A method for operating a memory system comprising a first node coupled to a second node by a network, the method comprising: receiving a remote transaction message from the second node in a processing element in the first node via the network, wherein the remote transaction message bypasses a main processor in the first node as it is transmitted to the processing element; accessing, by the processing element, data from a location in a memory in the first node based on the remote transaction message; and performing, by the processing element, computations based on the data and the remote transaction message.
