9 ucmatose [-s server_address] [-b bind_address] [-c connections]
10 [-C message_count] [-S message_size]
11 ucmatose -s server_address [-b bind_address] [-c connections]
12 [-C message_count] [-S message_size] [-t tos]
13
15 Establishes a set of reliable RDMA connections between two nodes using
16 the librdmacm, optionally transfers data between the nodes, then dis‐
17 connects.
18
20 -s server_address
21 The network name or IP address of the server system listening
22 for connections. The used name or address must route over an
23 RDMA device. This option must be specified by the client.
24
25 -b bind_address
26 The local network address to bind to.
27
28 -c connections
29 The number of connections to establish between the client and
30 server. (default 1)
31
32 -C message_count
33 The number of messages to transfer over each connection.
34 (default 10)
35
36 -S message_size
37 The size of each message transferred, in bytes. (default 100)
38
39 -t tos Indicates the type of service used for the communication. Type
40 of service is implementation dependent based on subnet configu‐
41 ration.
42
43 -m Tests event channel migration. Migrates all communication iden‐
44 tifiers to a different event channel for disconnect events.
45
47 Basic usage is to start ucmatose on a server system, then run ucmatose
48 -s server_name on a client system.

50 Because this test maps RDMA resources to userspace, users must ensure
51 that they have available system resources and permissions. See the
52 libibverbs README file for additional details.
