NAME
rdma_xclient - RDMA CM communication client test program
SYNOPSIS
rdma_xclient [-s server_address] [-p server_port] [-c comm_type]
DESCRIPTION
Uses synchronous librdmam calls to establish an RDMA connection between two nodes. This example is intended to provide a very simple cod- ing example of how to use RDMA.
OPTIONS
-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. -c communication type Specifies the type of communication established with the server program. 'r' results in using a reliable-connected QP (the default). 'x' uses extended reliable-connected XRC QPs.
NOTES
Basic usage is to start rdma_xserver, 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.
