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.

Command-Line Options#

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

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.

Console Commands#

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