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.
The local network address to bind to.
Indicates the size of the send and receive network
The number of messages to transfer from the client to the
server and back again on each iteration. (default 1000)
The size of each send transfer, in bytes. (default 1000)
The server's port number.
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
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
Because this test maps RDMA resources to userspace, users must
ensure that they have available system resources and permissions.
