NAME

6       ucmatose - RDMA CM connection and simple ping-pong test.
7

SYNOPSIS

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]

DESCRIPTION

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

OPTIONS

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

NOTES

47       Basic usage is to start ucmatose on a server system, then run  ucmatose
48       -s server_name on a client system.
49
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.
