This is the command ucmatose that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
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.
