NAME

6       rping - RDMA CM connection and RDMA ping-pong test.
7

SYNOPSIS

9       rping -s [-v] [-V] [-d] [-P] [-a address] [-p port]
10                 [-C message_count] [-S message_size]
11       rping -c [-v] [-V] [-d] [-I address] -a address [-p port]
12                 [-C message_count] [-S message_size]
13

DESCRIPTION

15       Establishes  a  reliable  RDMA  connection  between two nodes using the
16       librdmacm, optionally performs RDMA transfers between the  nodes,  then
17       disconnects.
18

OPTIONS

20       -s     Run as the server.
21
22       -c     Run as the client.
23
24       -a address
25              On the server, specifies the network address to bind the connec‐
26              tion to.  To bind to any address with IPv6 use -a ::0 .  On  the
27              client, specifies the server address to connect to.
28
29       -I address
30              The  address to bind to as the source IP address to use. This is
31              useful if you have multiple addresses on  the  same  network  or
32              complex routing.
33
34       -p     Port number for listening server.
35
36       -v     Display ping data.
37
38       -V     Validate ping data.
39
40       -d     Display debug information.
41
42       -C message_count
43              The  number  of  messages  to  transfer  over  each  connection.
44              (default infinite)
45
46       -S message_size
47              The size of each message transferred, in bytes.  (default 100)
48
49       -P     Run the server in persistent mode.  This allows  multiple  rping
50              clients  to connect to a single server instance. The server will
51              run until killed.
52
53       -q     Control QP Creation/Modification directly from the  application,
54              instead of rdma_cm.
55

NOTES

57       Because  this  test maps RDMA resources to userspace, users must ensure
58       that they have available system resources  and  permissions.   See  the
59       libibverbs README file for additional details.
