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 coding 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.
