Concurrent Launches Real-time Linux Support of SLI Graphics Technology

Concurrent ImaGen visual servers employ commercial-off-the-shelf (COTS) graphics and hardware technology with Concurrent's powerful real-time Linux operating systems. This combination enables unmatched performance and pricing and enables multiple channels of state-of-the-art visualization and graphics performance for simulation and modeling applications that require enhanced realism.

DULUTH, GA - May 16, 2006 - Concurrent (NASDAQ:CCUR), a leading provider of time-critical Linux® operating systems and integrated computer solutions for mission-critical applications, today announced the launch of a new version of its popular ImaGen real-time visual servers with Concurrent's real-time Linux operating system. Available now, the upgraded product features Scalable Link Interface (SLI) technology that dramatically increases graphics performance.

"SLI is a method for linking two or more graphics cards to produce a single output. The SLI enhancements to our ImaGen platform yield unprecedented image quality and fidelity," said Ken Jackson, Vice-President of Concurrent Special Systems. "Our ImaGen Linux-based visual servers truly offer the highest graphics performance at reasonable price points ensuring that application developers will have access to the best possible COTS IG solutions."

Concurrent ImaGen visual servers employ commercial-off-the-shelf (COTS) graphics and hardware technology with Concurrent's powerful real-time Linux operating systems. This combination enables unmatched performance and pricing and enables multiple channels of state-of-the-art visualization and graphics performance for simulation and modeling applications that require enhanced realism. Typical applications include civil and military simulation, mission planning, homeland security, scientific and medical visualization, architectural design, energy exploration, and entertainment. ImaGen supports a full range of powerful graphics software for real-time 3D visualization, simulation and training applications. Available software products include Multigen-Paradigm's Vega Prime(TM), Diamond Visionics' GenesisRT, DiSTI's GL Studio(TM) and OpenSceneGraph, an open-source 3D graphics toolkit.

Concurrent's new SLI ImaGen solutions also feature genlock and framelock, technology for synchronizing multiple video or image frames externally (genlock) or internally (framelock). SLI technology provides the ability to combine the rendering power of two separate PCIe graphics cards into a single output for substantially increased graphical performance. SLI-capable graphics systems offer an order of magnitude greater fill rate performance compared to the graphics cards of a few years ago.
