REDUCED NETWORK LOAD WITH COMBINED PUT OR GET AND RECEIVER-MANAGED OFFSET

Abstract:

Methods and apparatus for reduced network load with receiver-managed offset (RMO) PUT or GET messages. An RMO PUT message including an RMO key, data, and a length is sent from an initiator to a target, where the RMO key is extracted by a Network Interface controller (NIC), SmartNIC, or Infrastructure Processing Unit and used to identify an address or address offset of a memory buffer in a target memory at which to write the data. An RMO GET message is sent from an initiator to a target and includes an RMO key, a source buffer on the target, and a length. The target processes the RMO GET, reads the length of data from its source buffer, and returns a message to the initiator including the RMO key, the read data, and the length. The RMO key is extracted and used to identify an address or address offset of a memory buffer in a memory on the initiator in which to write the read data.
