16k tiled display
During FIA'11 we have demonstrated for the first our high resolution visualization panel which consists of 64 24'' LCD each of resolution of 1920 wide and 1200 high which is more than full HD picture. Thus, the total resolution of our tiled display was 15 360 pixels wide and 9 600 pixels high (almost 150 megapixels in total). The physical dimension of the display is about 4.5 meters wide and 3 meters height. This setup provides and extraordinary visualization space with pixel resolution much higher than most of exiting visualization walls. Our experimental visualization display offers completely new capabilities that can be applied in scientific or business visualizations and virtual remote group cooperation. The visualization setup is driven by open source software. Depending on the application scenario we use one of the following software tool-kits:
- SAGE - ''Salable Adaptive Graphics Environment'' - SAGE is a pixel streaming system supporting high and continuous display resolutions. With the use of optical networks of up to 100Gbit throughput, SAGE can potentially operate multi-display visualization environments. The SAGE network architecture allows many users to simultaneously run various applications (such as 3D rendering, remote desktop, video streams and 2D maps) on local or remote clusters. Moreover, they can easily share their applications via the modern networks by streaming the pixels of each application over ultra-high-speed networks to the tiled displays. The output of any M by N pixel rendering application is streamed to X by Y pixel region of the display allowing users definable layouts on the display. The dynamic pixel routing capability of SAGE lets users freely move and resize each of the application's windows,
- benefits: SAGE network architecture allows multiple users to simultaneously run any application on local or remote pc or cluster and use the wall as a large remote desktop - multiple application windows can be displayed simultaneously, each window can be freely moved, resized an so on. Easy application integration.
- Equalizer Graphics library - which is an OpenGL based solution for high performance parallel rendering,
- benefits: Increased performance and visual quality. Robust rendering of complex geometries or volume data.
- Vitrall - our own implementation of distributed web based visualization system.
- benefits: support for innovative user interfaces, mobile devices and thin clients for easy collaboration and visualization session sharing.

100Gbit Ethernet connection for 16K visualization
For the purpose of the visualization applications scenarios we have prepared an innovative HPC testbed setup where many-core and accelerated hardware (GPUs) can be used used in conjunction with high-speed networks. One of the key requirements of the modern visualization scenarios is an access to fast (10GBit or even faster up to 100GBit) optical networks that can effectively link computing resources with high-resolution visualization panels aiming at the 16K resolution (64 x Full HD). The setup can then be used to visualize online and offline results of various scientific application, including multimedia streaming, real-time many-core processing, 3D Internet, bio-chemistry, nanotechnology and many more. Moreover, the setup can be used to run various application benchmarks to identify potential bottlenecks for both software and hardware. A sample of architecture for the 16K visualization setup is presented in Figure 1. This architecture was actually deployed and tested at PSNC in 2011??. It was based on two 100Gb routers, each equipped with one 100Gb port and ten 10Gb ports. One of them was placed in data center where up to ten fast multicore Intel servers were connected with it by 10Gb links. The second router was placed near 16K display. Both routers were connected remotely with 100Gbit Ethernet optical link. The visualization 16K panel was driven by to up to ten pc computers connected with the second router with 10Gb links. Each of these pc's was operating up to 6 to 12(depending on the actual demo configuration) LCD tiles of the visualization tiled-display.
