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.
