NAME

6       udpong - unreliable datagram streaming over RDMA ping-pong test.
7

SYNOPSIS

9       udpong [-s server_address] [-b bind_address]
10                      [-B buffer_size] [-C transfer_count]
11                      [-S transfer_size] [-p server_port] [-T test_option]
12

DESCRIPTION

14       Uses unreliable datagram streaming over RDMA protocol (rsocket) to con‐
15       nect and exchange data between a client and server application.
16

OPTIONS

18       -s server_address
19              The network name or IP address of the  server  system  listening
20              for  connections.   The  used name or address must route over an
21              RDMA device.  This option must be specified by the client.
22
23       -b bind_address
24              The local network address to bind to.
25
26       -B buffer_size
27              Indicates the size of the send and receive network buffers.
28
29       -C transfer_count
30              The number of messages to transfer from the client to the server
31              and back again on each iteration.  (default 1000)
32
33       -S transfer_size
34              The size of each send transfer, in bytes.  (default 1000)
35
36       -p server_port
37              The server's port number.
38
39       -T test_option
40              Specifies test parameters.  Available options are:
41
42       s | socket  - uses standard socket calls to transfer data
43
44       a | async - uses asynchronous operation (e.g. select / poll)
45
46       b | blocking - uses blocking calls
47
48       n | nonblocking - uses non-blocking calls
49
50       e | echo - server echoes all messages
51

NOTES

53       Basic  usage  is to start udpong on a server system, then run udpong -s
54       server_name on a client system.  udpong will run a  series  of  latency
55       and bandwidth performance tests.  Specifying a different transfer_count
56       or transfer_size will run a user customized test using  default  values
57       where none have been specified.
58
59       Because  this  test maps RDMA resources to userspace, users must ensure
60       that they have available system resources  and  permissions.   See  the
61       libibverbs README file for additional details.
