NAME

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

SYNOPSIS

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

DESCRIPTION

Uses unreliable datagram streaming over RDMA protocol (rsocket) to connect and exchange data between a client and server application.

OPTIONS

-s server_address: The network name or IP address of the server system listening for connections. The used name or address must route over an RDMA device. This option must be specified by the client.
-b bind_address: The local network address to bind to.
-B buffer_size: Indicates the size of the send and receive network buffers.
-C transfer_count: The number of messages to transfer from the client to the server and back again on each iteration. (default 1000)
-S transfer_size: The size of each send transfer, in bytes. (default 1000)
-p server_port: The server's port number.
-T test_option: Specifies test parameters. Available options are:

s | socket - uses standard socket calls to transfer data

a | async - uses asynchronous operation (e.g. select / poll)

b | blocking - uses blocking calls

n | nonblocking - uses non-blocking calls

e | echo - server echoes all messages

NOTES

Basic usage is to start udpong on a server system, then run udpong -s server_name on a client system. udpong will run a series of latency and bandwidth performance tests. Specifying a different transfer_count or transfer_size will run a user customized test using default values where none have been specified.

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