UCMATOSE(1)			   librdmacm			   UCMATOSE(1)

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

       -f address_format
	      Specifies	the format of the server and  bind  address.   Be  de-
	      fault, 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.  (de-
	      fault 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 li-
       bibverbs	README file for	additional details.
