Abstract
Shared memory communication is facilitated between systems of a computing environment capable of communicating over a network using transmission control protocol/Internet protocol (TCP/IP). The network includes a network path between one system and another system of the computing environment, where the network path passes through one or more routers of the network. The facilitating includes obtaining performance-related data for shared memory communication of the one system with the other system across the network path using a remote direct memory access (RDMA) protocol. Based on the performance-related data, the facilitating includes dynamically determining whether to use the RDMA protocol for shared memory communication of the one system with the other system across the network path, rather than the TCP/IP protocol.
