NAME

       ibv_srq_pingpong - simple InfiniBand shared receive queue test

SYNOPSIS

       ibv_srq_pingpong [-p port] [-d device] [-i ib port] [-s size] [-q num QPs] [-r rx depth] [-n iters] [-l sl] [-e] HOSTNAME

       ibv_srq_pingpong [-p port] [-d device] [-i ib port] [-s size] [-q num QPs] [-r rx depth] [-n iters] [-l sl] [-e]

DESCRIPTION

       Run a simple ping-pong test over InfiniBand via the reliable connected (RC) transport, using multiple queue pairs (QPs) and a single shared
       receive queue (SRQ).

OPTIONS

       -p, --port=PORT
	      use TCP port PORT for initial synchronization (default 18515)

       -d, --ib-dev=DEVICE
	      use IB device DEVICE (default first device found)

       -i, --ib-port=PORT
	      use IB port PORT (default port 1)

       -s, --size=SIZE
	      ping-pong messages of size SIZE (default 4096)

       -q, --num-qp=NUM
	      use NUM queue pairs for test (default 16)

       -r, --rx-depth=DEPTH
	      post DEPTH receives at a time (default 1000)

       -n, --iters=ITERS
	      perform ITERS message exchanges (default 1000)

       -l, --sl=SL
	      use SL as the service level value of the QPs (default 0)

       -e, --events
	      sleep while waiting for work completion events (default is to poll for completions)

BUGS

       The network synchronization between client and server instances is weak, and does not prevent incompatible options from being used  on  the
       two  instances.	 The  method  used for retrieving work completions is not strictly correct, and race conditions may cause failures on some
       systems.
