ibv_ud_pingpong - simple InfiniBand UD transport test SYNOPSIS
ibv_ud_pingpong [-p port] [-d device] [-i ib port] [-s size] [-r rx depth] [-n iters] [-l sl] [-e] HOSTNAME ibv_ud_pingpong [-p port] [-d device] [-i ib port] [-s size] [-r rx depth] [-n iters] [-l sl] [-e] DESCRIPTION
Run a simple ping-pong test over InfiniBand via the unreliable datagram (UD) transport. 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 2048) -r, --rx-depth=DEPTH post DEPTH receives at a time (default 500) -n, --iters=ITERS perform ITERS message exchanges (default 1000) -l, --sl=SL send messages with service level SL (default 0) -e, --events sleep while waiting for work completion events (default is to poll for completions) SEE ALSO

Roland Dreier <rolandd@cisco.com> 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. libibverbs August 30, 2005 IBV_UD_PINGPONG(1)

SMPDUMP(8) OpenIB Diagnostics SMPDUMP(8) NAME
smpdump - dump InfiniBand subnet management attributes SYNOPSIS
smpdump [-s(ring)] [-D(irect)] [-C ca_name] [-P ca_port] [-t(imeout) timeout_ms] [-V(ersion)] [-h(elp)] <dlid|dr_path> <attr> [mod] DESCRIPTION
smpdump is a general purpose SMP utility which gets SM attributes from a specified SMA. The result is dumped in hex by default. OPTIONS
attr IBA attribute ID for SM attribute mod IBA modifier for SM attribute COMMON OPTIONS
Most OpenIB diagnostics take the following common flags. The exact list of supported flags per utility can be found in the usage message and can be shown using the util_name -h syntax. # Debugging flags -d raise the IB debugging level. May be used several times (-ddd or -d -d -d). -e show send and receive errors (timeouts and others) -h show the usage message -v increase the application verbosity level. May be used several times (-vv or -v -v -v) -V show the version info. # Addressing flags -D use directed path address arguments. The path is a comma separated list of out ports. Examples: "0" # self port "0,1,2,1,4" # out via port 1, then 2, ... -G use GUID address argument. In most cases, it is the Port GUID. Example: "0x08f1040023" -s <smlid> use 'smlid' as the target lid for SM/SA queries. # Other common flags: -C <ca_name> use the specified ca_name. -P <ca_port> use the specified ca_port. -t <timeout_ms> override the default timeout for the solicited mads. Multiple CA/Multiple Port Support When no IB device or port is specified, the port to use is selected by the following criteria: 1. the first port that is ACTIVE. 2. if not found, the first port that is UP (physical link up). If a port and/or CA name is specified, the user request is attempted to be fulfilled, and will fail if it is not possible. EXAMPLES
Direct Routed Examples smpdump -D 0,1,2,3,5 16 # NODE DESC smpdump -D 0,1,2 0x15 2 # PORT INFO, port 2 LID Routed Examples smpdump 3 0x15 2 # PORT INFO, lid 3 port 2 smpdump 0xa0 0x11 # NODE INFO, lid 0xa0 SEE ALSO
