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 times that the specified number of messages
will be exchanged between the client and server. (default
The number of messages to transfer from the client to the
server and back again on each iteration. (default 1)
The size of each send transfer, in bytes. (default 1000)
If 'all' is specified, rstream will run a series of tests
of various sizes.
The server's port number.
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.
