NAME

       dtestx - simple uDAPL extensions test

SYNOPSIS

       dtestx [-vmpqc] [-u|-U ep num] [-P provider] [-b buf size] [ -s | -h HOSTNAME ]

DESCRIPTION

       dtestx  is a simple test used to test extensions to the DAT API.  At least two instantiations of the test
       must be run. One acts as the server and the other the client. The server side of the test,  once  invoked
       listens for connection requests, until timing out or killed. Upon receipt of a cd connection request, the
       connection is established, the  server  and  client  sides  exchange  information  necessary  to  perform
       extensions test.

       Extensions tests are:
               1. Post rdma write with immediate data
               2. Atomic compare and swap
               3. Atomic fetch and add
               Note: In case -q is set only query test will run.

OPTIONS

       -P=PROVIDER
              use PROVIDER to specify uDAPL interface using /etc/dat.conf (default ofa-v2-mlx4_0-1u)

       -h=HOSTNAME
              use HOSTNAME to specify server hostname or IP address (default - none)

       -b=BUFFER_SIZE
              use buffer size BUFFER_SIZE for RDMA(default 64)

       -U=EP_COUNT
              use EP_COUNT to specify unreliable datagram test with EP_COUNT UD endpoints (default - none)

       -v, verbose output(default off)

       -q, query only test (default off)

       -u, unreliable datagram test (default no)

       -s, run as server (default - run as server)

       -c, run as client (for non UD tests, -h is always client)

       -p, print counters. Provide IA, EP, or EVD and call will print appropriate counters (default off)

       -m,  multi  ep.  in ud test only. receive multi messages on single EP. (default off - receive one message
       across multiple EPs)

EXAMPLES

       dtestx -P ofa-v2-ib0 -v -s

            Starts a server process with debug verbosity using provider ofa-v2-ib0.

       dtestx -P ofa-v2-ib0 -h server1-ib0

            Starts a client process, using ofa-v2-ib0 provider to connect to hostname server1-ib0.
