rstream

RSTREAM(1)							     librdmacm								RSTREAM(1)

NAME

       rstream - streaming over RDMA ping-pong test.

SYNOPSIS

       rstream [-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:

       s | socket  - uses standard socket calls to transfer data

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

       b | blocking - uses blocking calls

       f | fork - fork server processing (forces -T s option)

       n | nonblocking - uses non-blocking calls

       v | verify - verifies data transfers

NOTES

       Basic  usage  is  to  start rstream on a server system, then run rstream -s server_name on a client system.  By default, rstream 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.
