Concurrent Debuts ImaGen High-Performance, Linux-based Visual Servers

4/22/2004 - Concurrent Computer Corporation (NASDAQ: CCUR), Integrated Solutions Division, a leading provider of integrated computer solutions for mission-critical applications, announced the introduction of its ImaGen family of high-performance, multi-channel visual servers. High-end image generation (IG), once achievable only on large, costly, dedicated visual systems, is now available on Concurrent ImaGen Linux-based servers employing commercial-off-the-shelf (COTS) graphics technology.

Concurrent’s ImaGen is the ideal imaging platform for today's simulation and modeling applications that require enhanced realism and the ability to process very large amounts of input data. Typical ImaGen imaging applications include civil and military simulation, mission planning, homeland security, scientific and medical visualization, architectural design, energy exploration and entertainment. ImaGen servers can also be used with Concurrent’s iHawkTM host multiprocessors to provide a complete training system platform with the highest levels of computer-generated image quality and fidelity.

High-Performance 3D Graphics
Concurrent’s ImaGen features the latest, industry-standard components from leading graphics suppliers, ensuring that application developers will have access to the best possible COTS IG solutions. ImaGen servers feature multiple Intel® XeonTM processors and a range of tower or rackmount enclosures. ImaGen can be configured with a choice of powerful dual-monitor-capable graphics controllers such as those offered by NVIDIA, ATI and 3DLabs. Loaded with popular 3D visualization software like Multigen-Paradigm’s Vega PrimeTM, DiSTI’s GL StudioTM, OpenGL, and OpenSceneGraph, ImaGen is the most flexible high-performance Linux-based graphics platform available today.

ImaGen servers are powered by Concurrent's RedHawk Linux real-time operating system. RedHawk Linux, is also featured on Concurrent iHawk multiprocessors, the industry’s leading Linux environment for deterministic, real-time applications. RedHawk is compatible with the popular Red Hat® Linux distribution.

Combiner Technology
Any number of ImaGen image generation servers can be linked together to produce a single unified output image to any desired level of photorealism. For example, the power of individual ImaGen servers can be assigned to render specific subsets of an image in parallel. Subset images are automatically assembled by Orad VR-X compositor hardware to produce a total image in unprecedented aggregate speeds of up to 1.3 billion polygons and 21 billion pixels per second. ImaGen servers support a variety of image combining modes such as sample division for anti-aliasing, time division, image division, eye division and volume division for large rendering applications.

Image Synchronization
ImaGen servers offer a full range of video synchronization capabilities. Commercial and military flight, maritime and driving simulators often require multiple displays to provide photorealistic views of an environment as seen from a cockpit, window or control panel. ImaGen framelock features can provide a seamless viewing experience in these multiple display applications. ImaGen genlock functionality enables synchronization with standard video signal formats or house-sync signals providing a powerful solution for display, video debrief and compositing.

“ImaGen leverages COTS products to provide high-end visualization and graphics performance,” said Ken Jackson, Concurrent vice president of Business Development. “We are pleased to provide a powerful, expandable and easily upgradeable IG solution to our customers in the simulation and training industries.”
