riostream - Online in the Cloud

PROGRAM:

NAME

riostream - zero-copy streaming over RDMA ping-pong test.

SYNOPSIS

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

DESCRIPTION

Uses the 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.

-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

NOTES

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.
