NAME
       ucmatose - RDMA CM connection and simple ping-pong test.

SYNOPSIS
       ucmatose [-s server_address] [-b bind_address]
                 [-f address_format] [-P port_space]
                 [-c connections] [-C message_count] [-S message_size]
       ucmatose -s server_address [-b bind_address]
                 [-f address_format] [-P port_space]
                 [-c connections] [-C message_count] [-S message_size] [-t tos]

DESCRIPTION
       Establishes a set of reliable RDMA connections between two nodes using
       the librdmacm, optionally transfers data between the nodes, then
       disconnects.

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.  To bind to any address
              with IPv6 use -b ::0 .

       -f address_format
              Specifies the format of the server and bind address.  Be
              default, the format is determined by getaddrinfo() as either
              being a hostname, an IPv4 address, or an IPv6 address.  This
              option may be used to indicate that a specific address format
              has been provided.  Supported address_format values are: name,
              ip, ipv6, and gid.

       -P port_space
              Specifies the port space for the connection.  Be default, the
              port space is the RDMA TCP port space. (Note that the RDMA port
              space may be separate from that used for IP.)  Supported
              port_space values are: tcp and ib.

       -c connections
              The number of connections to establish between the client and
              server.  (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.  (default 100)

       -t tos Indicates the type of service used for the communication.  Type
              of service is implementation dependent based on subnet
              configuration.

       -m     Tests event channel migration.  Migrates all communication
              identifiers to a different event channel for disconnect events.

NOTES
       Basic usage is to start ucmatose on a server system, then run ucmatose
       -s server_name 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.
