Boosting remote direct memory access performance using cryptographic hash based approach |
摘要 |
A mechanism is provided in a data processing system for performing a remote direct memory access operation. Responsive to receiving in a network interface controller a hash value of data to be copied from a source address in a source node to a destination address in a destination node in the remote direct memory access operation, the network interface controller performs a lookup operation in a translation protection table in the network interface controller to match the hash value to a hash value for data existing in memory of the destination node. Responsive to the network interface controller finding a match in the translation protection table, the network interface controller completes the remote direct memory access operation without transferring the data from the source node to the destination node. |
