Syncker-Specific Options

There are 2 types of Syncker-specific options:

Command-line options used to specify screen configuration, addressing mode, multicast address of the Master computer, or a port to be used on the application start-up. These options have the same syntax as the other start-up command-line options.
Console options that can be run from the application console on the Master or Slave sides.

Common Options#

The following command-line options can be run on Master or Slave application start-up:

Name	Description	Arguments	Default
sync_init	Initializes Syncker. Shell commands `-sync_init 1`	Flag.	1
sync_master	Sets the flag indicating whether the computer is Master. Shell commands `-sync_master 1`	Master flag.	1
sync_method	Sets the addressing mode to be used by Syncker. One of the following: unicast, multicast, broadcast. Shell commands `-sync_method broadcast`	Addressing mode.	unicast
sync_multicast_address	Sets a multicast address that is used by the Master computer to send messages to Slave over the network. Shell commands `-sync_multicast_address "xxx.xxx.xxx.xxx"`	A multicast address in the xxx.xxx.xxx.xxx format.	239.0.0.1
sync_port	Sets the UDP port to be used to send and receive messages for the Syncker. Shell commands `-sync_port 8890`	UDP port number.	8890
sync_swap	Sets the buffer swapping method to be used by Syncker. One of the following: default, NVIDIA (available only for NVIDIA Quadro GPUs with G-SYNC support). Shell commands `-sync_swap nvidia`	Buffer swap synchronization mode.	default
sync_swap_nvidia_group	Sets NVIDIA's swap group. Shell commands `-sync_swap_nvidia_group 1`	NVIDIA's swap group.	1
sync_swap_nvidia_barrier	Sets NVIDIA's swap barrier. Shell commands `-sync_swap_nvidia_barrier 1`	NVIDIA's swap barrier.	1
computer_name	Sets the name of the computer to be used in viewport configuration stored in the configuration file. Shell commands `-computer_name <comp_name>`	Computer name.	—

Master Options#

The following command-line options can be run on the Master application start-up:

Name	Description	Arguments	Default
sync_count	Sets a number of Syncker hosts (including Master itself) in the network. Shell commands `-sync_count 3`	Number of hosts.	1
sync_broadcast_address	Sets a broadcast address of the Master computer that is used to broadcast messages to Slave over the network. If the key is not specified, Syncker shall try to determine the value automatically. Shell commands `-sync_broadcast_address "xxx.xxx.xxx.xxx"`	A broadcast address in the xxx.xxx.xxx.xxx format.	—
sync_allow_extra_slaves	Sets the flag indicating whether additional Slave PCs can be connected after starting the session. Shell commands `-sync_allow_extra_slaves 1`	Extra Slave flag.	0

Slave Options#

The following command-line options can be run on the Slave application start-up:

Name	Description	Arguments	Default
sync_slave_port	Sets a UDP port to be used by Slave. 0 — means any unused port available. Shell commands `-sync_slave_port 0`	UDP port number.	0
sync_master_address	Sets the address of the Master computer. If the key is not specified, Syncker shall try to determine the value automatically. Shell commands `-sync_master_address "xxx.xxx.xxx.xxx"`	Master's address in the xxx.xxx.xxx.xxx format.	—

The following console commands can be run on a Master or Slave computer.

Name	Description	Arguments
sync	Command. Runs the specified console command on Master and all Slave PCs. Source code `sync show_profiler 3 //shows the profiler on all computers`	A console command to run.
syncker_interpolation	Variable. Prints the value indicating if interpolation and extrapolation are enabled on the computer. Command. Enables or disables interpolation and extrapolation on the computer. Source code `syncker_interpolation 1`	0 — disabled 1 — enabled (by default)
syncker_interpolation_period	Variable. Prints the current interpolation period value for the computer, in seconds. Command. Sets the interpolation period for the computer. Source code `syncker_interpolation_period 0.04`	Interpolation period, in seconds (0.04 — by default)
syncker_extrapolation_period	Variable. Prints the current extrapolation period value for the computer, in seconds. Command. Sets the extrapolation period for the computer. Source code `syncker_extrapolation_period 0.2`	Extrapolation period, in seconds (0.0 — by default)
syncker_setup	Variable. Prints the value indicating if screen/ projection setup mode is active. Command. Enables or disables screen/ projection setup mode. Source code `syncker_setup 1`	0 — return to standard mode. 1 — enter the screen/ projection setup mode.
syncker_debug	Variable. Prints the value indicating if the debug window is active. Command. Shows or hides the debug window. Source code `syncker_debug 1`	0 — hide the debug window. 1 — show the debug window.
