rdma_server(1) simple RDMA CM connection and ping-pong test.


rdma_server [-p port]


Uses synchronous librdmam calls to establish an RDMA connections between two nodes. This example is intended to provide a very simple coding example of how to use RDMA.


-p port
Changes the port number that the server listens on. By default the server listens on port 7471.


Basic usage is to start rdma_server, then connect to the server using the rdma_client program.

Because this test maps RDMA resources to userspace, users must ensure that they have available system resources and permissions. See the libibverbs README file for additional details.
