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


rdma_client [-s server_address] [-p server_port]


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


-s server_address
Specifies the address of the system that the rdma_server is running on. By default, the client will attempt to connect to the server using
-p server_port
Specifies 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.
