14 Quadro Sync - Focus on the image not the artifacts

15 WHY IS SYNC IS IMPORTANT? Bezel s hide sync issues!!! Image from gizmodo.com

16 MULTI-GPU SYNC Framelock Stereo lock Swap lock

17 VERTICAL SYNC t0 t0 + t1 t0 + t2 Display 1 Display 2 Display 3 t0 t0 + t1 t0 + t2 Vertical Sync is the pulse that indicates the start of the display refresh. To avoid tearing on a single screen the application swap buffers are synced to vertical sync. Although all three displays may have the same refresh rate vertical sync start may be different. This can result in tearing between displays.

18 FRAMELOCK/GENLOCK t0 t0 t0 Display 1 Display 2 Display 3 Framelock/Genlock provides a common sync signal between graphics cards to insure the vertical sync pulse starts at a common start. This is commonly referred to as Frame Synchronization Framelock Synchronization is generated from a master node. All other nodes would be sync to this. Genlock synchronization is from an external sync generator (house sync). Each node attached to the genlock signal is synced from that signal. Framelock & Genlock can be mixed in the cluster. With the master node being synchronized from the genlock pulse

19 STEREO LOCK Frame 1 Frame 2 Frame 3 Frame 4 Frame 5 Frame 6 V Sync 120Hz VESA Stereo Sync High left Low right No information that tells a display or stereo glasses which eye is left or right

20 STEREO LOCK Framelock GPU 1 No stereo lock GPU 2 This will result in eyes being swapped between displays

21 STEREO LOCK GPU 1 stereo lock GPU 2 Stereo sync is in phase between GPUs

22 SWAPBUFFERS Front Swap Swap Swap Swap Back Front Back Swap GPU Draw (1) Draw (2) Draw (3) Draw (4) Back Front Back Front Display Scan Scan (1) Scan (2) Scan (3) Scan (4)

23 SWAPBUFFERS Front Swap Swap Swap Back Front Back GPU Draw (1) Draw (2) Draw (3) Back Front Back Front Display Scan Scan (1) Scan (1) Scan (2) Scan (3) Time (ms)

24 SWAPBUFFERS IN A CLUSTER Node 1 Node 2 Node 3 Node 4 Each node is now rendering a scene with different complexity i.e from least to highest we get: 1. node 3 ~ 16ms = 60fps 2. node 4 ~ 36ms = 30fps 3. node 2 ~ 53ms = 15fps 4. node 1 ~ 99ms = 10fps With each node running at a different rate the user would perceive tearing on the screen. We need a mechanism to ensure that each node will swap at the same time.

25 SWAP GROUP AND SWAP BARRIER NVIDIA Extensions to OpenGL /DirectX (via NVAPI) Swap Group provides synchronization multiple GPUs in a single host Swap Barrier provides synchronization of GPUs across multiple nodes. Use RJ45 (framelock) connection on Quadro Sync so faster than sync over a network Node 1 Node 2 Node 3 Node 4 With Swap Barrier each node will wait until all nodes have completed their render 1. node 3 ~ 16ms = 10fps 2. node 4 ~ 36ms = 10fps 3. node 2 ~ 53ms = 10fps 4. node 1 ~ 99ms = 10fps

26 WHAT DOES SYNC DO Synchronize Multiple Displays Co-ordinate Buffer Swaps Align the scan out of multiple displays, GPU s, and systems HW based swap synchronization within a node or between clusters Maintain Stereo alignment between multiple systems Prevent tearing and image mis-alignment Synchronize to an internal or external timing source

27 G-SYNC GAMING MONITORS Approaches the problem differently GSYNC is a module put into the display Currently vsync tells GPU when to update Gsync tells the display when to update Currently only works for single displays attached Future version may support multiple displays.

28 MOSAIC - Setup and configuration

Even using Quadro Sync its called SLI MOSIAC

30 SETTING UP MOSAIC Control Panel Configuremosaic NVWMI NVAPI Large display walls Setup from a remote machine Powershell scripts Program directly Incorporate MOSAIC setup into your own application Driver Install Download from NVIDIA driver section Install with Driver under advanced options Registered Developer for NDA access NVAPI

31 MOSAIC GRIDS columns Rows x columns <= 16 Max Horizontal or vertical Pixels <= rows Vertical Pixels Enumeration of the Grid always starts top left and goes left to right Horizontal pixels

32 UNDERSTANDING TOPOLOGIES Column overlap or bezel correction Row Overlap or Bezel correction Bezel correction will increase overall pixel size i.e each display is 1920x1080 Bezel per column is 100 Total horizontal width = 1920* *3 = 7980 Overlap correction will decrease overall pixel size

33 BEZEL AND OVERLAP CORRECTION Bezel Correction Will make the image look continuous as we render under the bezel Overlap Correction For projectors it maintain the Aspect Ratio of the display.
