riostream - zero-copy streaming over RDMA ping-pong test.
riostream [-s server_address] [-b bind_address] [-B buffer_size]
[-I iterations] [-C transfer_count]
[-S transfer_size] [-p server_port] [-T test_option]
Uses the streaming over RDMA protocol (rsocket) to connect and
exchange data between a client and server application.
-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.
-I iterations
The number of times that the specified number of messages will
be exchanged between the client and server. (default 1000)
-C transfer_count
The number of messages to transfer from the client to the
server and back again on each iteration. (default 1)
-S transfer_size
The size of each send transfer, in bytes. (default 1000) If
'all' is specified, rstream will run a series of tests of
various sizes.
-p server_port
The server's port number.
-T test_option
Specifies test parameters. Available options are:
a | async - uses asynchronous operation (e.g. select / poll)
b | blocking - uses blocking calls
n | nonblocking - uses non-blocking calls
v | verify - verifies data transfers
Basic usage is to start riostream on a server system, then run
riostream -s server_name on a client system. By default, riostream
will run a series of latency and bandwidth performance tests.
Specifying a different iterations, 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.
