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.
