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

SYNOPSIS
       ucmatose [-s server_address] [-b bind_address] [-c connections]
		 [-C message_count] [-S message_size]
       ucmatose -s server_address [-b bind_address] [-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  dis‐
       connects.

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.

       -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  configu‐
	      ration.

       -m     Tests event channel migration.  Migrates all communication iden‐
	      tifiers 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.
