DESCRIPTION

17       Establishes  a set of reliable RDMA connections between two nodes using
18       the librdmacm, optionally transfers data between the nodes,  then  dis‐
19       connects.
20

OPTIONS

22       -s server_address
23              The  network  name  or IP address of the server system listening
24              for connections.  The used name or address must  route  over  an
25              RDMA device.  This option must be specified by the client.
26
27       -b bind_address
28              The  local  network  address to bind to.  To bind to any address
29              with IPv6 use -b ::0 .
30
31       -f address_format
32              Specifies the  format  of  the  server  and  bind  address.   Be
33              default,  the  format  is  determined by getaddrinfo() as either
34              being a hostname, an IPv4 address, or  an  IPv6  address.   This
35              option  may  be  used to indicate that a specific address format
36              has been provided.  Supported address_format values  are:  name,
37              ip, ipv6, and gid.
38
39       -P port_space
40              Specifies  the  port  space for the connection.  Be default, the
41              port space is the RDMA TCP port space. (Note that the RDMA  port
42              space  may  be  separate  from  that  used  for  IP.)  Supported
43              port_space values are: tcp and ib.
44
45       -c connections
46              The number of connections to establish between  the  client  and
47              server.  (default 1)
48
49       -C message_count
50              The  number  of  messages  to  transfer  over  each  connection.
51              (default 10)
52
53       -S message_size
54              The size of each message transferred, in bytes.  (default 100)
55
56       -t tos Indicates the type of service used for the communication.   Type
57              of  service is implementation dependent based on subnet configu‐
58              ration.
59
60       -m     Tests event channel migration.  Migrates all communication iden‐
61              tifiers to a different event channel for disconnect events.
62

NOTES

64       Basic  usage is to start ucmatose on a server system, then run ucmatose
65       -s server_name on a client system.
66
67       Because this test maps RDMA resources to userspace, users  must  ensure
68       that  they  have  available  system resources and permissions.  See the
69       libibverbs README file for additional details.
