RDMA systems and methods for sending commands from a source node to a target node for local execution of commands at the target node

摘要

The invention relates to a RDMA system for sending commands from a source node to a target node. These commands are locally executed at the target node. One aspect of the invention is a multi-node computer system having a plurality of interconnected processing nodes. The computer system issues a direct memory access (DMA) command from a first node to be executed by a DMA engine at a second node. Commands are transferred and executed by forming, at a first node, a packet having a payload containing the DMA command. The packets are sent to the second node via the interconnection topology, where the second node receives the packet and validating that the packet complies with a predefined trust relationship. The command is then processed by the DMA engine at the second node.
