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.
