rdma_client — 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 127.0.0.1.
- -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.
