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. SEE ALSO

NAME
mckey - RDMA CM multicast setup and simple data transfer test. SYNOPSIS
mckey -m multicast_address [-s] [-b bind_address] [-c connections] [-C message_count] [-S message_size] [-p port_space] mckey -m multicast_address -s [-b bind_address] [-c connections] [-C message_count] [-S message_size] [-p port_space] mckey -M unmapped_multicast_address -b bind_address [-s] [-c connections] [-C message_count] [-S message_size] [-p port_space] DESCRIPTION
Establishes a set of RDMA multicast communication paths between nodes using the librdmacm, optionally transfers datagrams to receiving nodes, then tears down the communication. OPTIONS
-m multicast_address IP multicast address to join. -M unmapped_multicast_address RDMA transport specific multicast address to join. -s Send datagrams to the multicast group. -b bind_address The local network address to bind to. -c connections The number of QPs to join the multicast group. (default 1) -C message_count The number of messages to transfer over each connection. (default 10) -S message_size The size of each message transferred, in bytes. This value must be smaller than the MTU of the underlying RDMA transport, or an error will occur. (default 100) -p port_space The port space of the datagram communication. May be either the RDMA UDP (0x0111) or IPoIB (0x0002) port space. (default RDMA_PS_UDP) NOTES
Basic usage is to start mckey -m multicast_address on a server system, then run mckey -m multicast_address -s on a client system. Unique Infiniband SA assigned multicast GIDs can be retrived by invoking mckey with a zero MGID or IP address. (Example, -M 0 or -m 0.0.0.0). The assigned address will be displayed to allow mckey clients to join the created group. 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. SEE ALSO
