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.
