mckey − RDMA CM multicast setup and simple data transfer test.
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] |
Establishes a set of RDMA multicast communication paths between nodes using the librdmacm, optionally transfers datagrams to receiving nodes, then tears down the communication.
−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)
Basic usage is to start mckey -m multicast_address on a server system, then run mckey -m multicast_address -s on a client system.
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.
