NAME

dtestsrq - simple uDAPL send/receive and RDMA test with shared receive queue. (SRQ)

SYNOPSIS

dtestsrq [-vu] [-P provider] [-b buf size] [-B burst size] [-t burst num] [-c connections] [-p port] [-S 0|1] [ -s | -h HOSTNAME ]

DESCRIPTION

dtestsrq is a simple test used to exercise and verify the uDAPL interfaces. 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 RDMA writes and reads. This test support SRQ so all the connections will share the same Rx Q.

OPTIONS

use PROVIDER to specify uDAPL interface using /etc/dat.conf (default ofa-v2-ib0)
use HOSTNAME to specify server hostname or IP address (default - none)
use buffer size BUFFER_SIZE for RDMA (default 64)
use burst size BURST_SIZE (default 1)
use burst count BURST_COUNT (default 3)
use port PORT_NUM (default 45248)
establish CONN_NUM connections (default = 1, max = 100)
use LID for server lid in ucm provider (default - none)
use QPN for server qpn in ucm provider (default - none)

EXAMPLES

dtestsrq -P ofa-v2-ib0 -s -c 10


Starts a server process with 10 connections using provider ofa-v2-ib0.
dtestsrq -P ofa-v2-ib0 -c 10 -h server1-ib0


Starts a client process with 10 connections, using ofa-v2-ib0 provider to connect to hostname server1-ib0.
