latency, and runs over Microsoft's NetworkDirect standard. The level of customizing for the user
is relatively high. User may choose to run with a customized message size, customized number
of iterations, or alternatively, customized test duration time. nd_write_lat runs with all message
sizes from 1B to 4MB (powers of 2), message inlining, CQ moderation.

The table below lists the various flags of the command.
8.4.15 nd_read_bw
This test is used for performance measuring of RDMA-Read requests in Microsoft Windows
Operating Systems. nd_read_bw is performance oriented for RDMA-Read with maximum
throughput, and runs over Microsoft's NetworkDirect standard. The level of customizing for the
user is relatively high. User may choose to run with a customized message size, customized num-
ber of iterations, or alternatively, customized test duration time. nd_read_bw runs with all mes-
sage sizes from 1B to 4MB (powers of 2), message inlining, CQ moderation.

Flag Description
-h Shows the Help screen.
-v Shows the version number.
-p Connects to the port <port> <default 6830>.
-s <msg size> Exchanges the message size with <default
65536B>, and it must not be combined with -a
flag.
-a Runs all the messages’ sizes from 1B to 8MB,
and it must not be combined with -s flag.
-n <num of iterations> The number of exchanges (at least 2, the default
is 100000)
-I <max inline size> The maximum size of message to send inline.
The default number is 128B.
-D <test duration in seconds> Tests duration in seconds.
-f <margin time in seconds> The margin time to avoid calculation, and it must
be less than half of the duration time.
-S <server interface IP> <server side only, must be last parameter>
-C <server interface IP> <client side only, must be last parameter>
-h Shows the Help screen.
