18 Synchronization - Focus on the image and not the artifacts

19 Why Sync is important Bezel s hide sync issues!!! Image from gizmodo.com

20 Differences between Premium Mosaic + Mosaic Frame Synchronization Vertical Sync to a common timing - without a physical connection between cards there is no method for having a common sync Effect is tearing Stereo Without frame sync there is no method for sync left/right eye between GPUS Overlap Without frame sync tearing would be most noticeable in a blend region. We disable this feature so tearing is not shown.

21 No Frame Sync t0 t0 t0+t1 t0+t1 GPU 0 - Display 0 GPU - Display 1 GPU 0 - Display 0 GPU - Display 1 t0 t0 + t1 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 four displays may have the same refresh rate vertical sync start between 2 GPUs will be different. This can result in tearing between displays.

22 Frame Sync on Mosaic with Sync t0 t0 t0 t0 GPU 0 - Display 0 GPU - Display 1 GPU 0 - Display 0 GPU - Display 1 t0 t0 Framelock 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 On SLI workstation - Framelock signal is provided across the SLI Bridge. Between Dual Quadro Plex s framelock signal is provided over the CAT5 cable On K5000 with Quadro Sync framelock signal is provided by the Quadro Sync

23 Frame Sync on Mosaic with Sync t0 t0 t0 t0 GPU 0 - Display 0 GPU - Display 1 GPU 0 - Display 0 GPU - Display 1 t0 t0 Framelock 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 On SLI workstation - Framelock signal is provided across the SLI Bridge. All 3 examples there is a physical connection between the GPUs. Between Dual Quadro Plex s framelock signal is provided over the CAT5 cable On K5000 with Quadro Sync framelock signal is provided by the Quadro Sync

90 Quadro Sync/GSync II Hardware + Software Sync Hardware RJ45 Framelock for synchronization of multiple displays to a common internal sync BNC/Genlock - Framelock for synchronization of multiple displays to a common external house sync Software Requires application to be written with extensions Swap Group and Swap Barrier are OpenGL & DirectX Extensions that provide enhanced synchronization of the graphics swap buffer. Quadro Sync G-Sync II

91 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.

92 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

93 Swapbuffers Mono OpenGL applications have two buffers Back Front The application will render into one buffer while the pixels are read to the screen from the other buffer. Once the render process is complete the buffers swap. i.e Front render Back read to screen swap Back render Front - read to screen.

94 Swapbuffers Swap between the two buffers will occur: On the first vertical sync after the Render process completes For example at 60Hz refresh rate we have ms to complete the render of a frame If render time = 10ms frame rate will be 60 fps (we swap on vertical sync) If render time = 17 ms frame rate will be 30 fps (we swap on the next vertical sync).

95 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.

96 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

97 New Quadro Sync features Increased Swap Barrier Support Up to 25 Quadro Sync cards in single chain. 50 Quadro Sync cards in a cluster 4 GPUs per Quadro Sync 200 GPUs with Swap Barrier Support Sync Delay and Skew settings Ability to adjust sync delay per Quadro card.
