Quadro Sync

  • Focus on the image not the artifacts
slide-15
SLIDE 15

WHY IS SYNC IS IMPORTANT?

slide-16
SLIDE 16

MULTI-GPU SYNC

  • Framelock
  • Stereo lock
  • Swap lock
slide-17
SLIDE 17

VERTICAL SYNC

Display 1 Display 2 Display 3

  • 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.

t0 t0 + t1 t0 + t2 t0 t0 + t1 t0 + t2

slide-18
SLIDE 18

FRAMELOCK/GENLOCK

Display 1 Display 2 Display 3

t0 t0 t0

  • 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

STEREO LOCK

No information that tells a display or stereo glasses which eye is left or right

VESA Stereo Sync

STEREO LOCK

GPU 1 GPU 2 No stereo lock This will result in eyes being swapped between displays

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.
slide-25
SLIDE 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
  • ver 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

WHAT DOES SYNC DO

Synchronize Multiple Displays

  • Align the scan out of multiple

displays, GPU’s, and systems

  • Maintain Stereo alignment

between multiple systems

  • Synchronize to an internal or

external timing source Co-ordinate Buffer Swaps

  • HW based swap synchronization within a

node or between clusters

  • Prevent tearing and image mis-alignment
slide-27
SLIDE 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.

Column overlap or bezel correction

11 10 12 13 15 14 16

Bezel correction will increase overall pixel size i.e each display is 1920x1080 Bezel per column is 100 Total horizontal width = 1920*4 + 100*3 = 7980

Overlap correction will decrease overall pixel size

slide-33
SLIDE 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.

NVIDIA DRIVER AUTOMATICALLY SWITCHES TO HDMI SIGNALING

  • HDMI over DVI

— Driver detects HDMI device — Switches to HDMI signaling — Uses DVI single line cables – no need for dual link DVI to HDMI cable

Quadro K5000 and K6000 can drive up to 4 HDMI 4K devices from a single card. Two via DP dongles and two via DVI.

  • DP to HDMI dongles

— Type 2 dongle

  • spec introduced Jan 2013 by VESA.

— Supports 4K HDMI devices — Passive dongle

DISPLAY PORT 1.2 MST CONNECTIVITY

  • Display Port 1.2 input
  • Panel acts a Multi-streaming hub
  • So two 1920x2160 channels over single cable
  • Vesa Display ids
  • New extension to VESA EDID standard
  • EDID identifies its preferred display resolution.
  • New extension identifies position in tiled display
  • NVIDIA driver (R331) will automatically enable

MOSAIC when it detects these displays to give single Desktop.
