Concurrent iHawk Chosen for Unmanned Combat Aircraft Vehicle Simulation by Leading Italian Aerospace Company Alenia Aeronautica.

ATLANTA -- Concurrent's Real-Time Linux(R)-Based Platform to Serve as Alenia's Next Generation UCAV Simulation Host and Image Generation (IG) Systems

Concurrent Computer Corporation (NASDAQ: CCUR), Integrated Solutions Division (ISD), today announced that Alenia Aeronautica/Finmeccanica has purchased Concurrent's iHawk(TM) Intel(R)-Xeon(R) graphics systems powered by RedHawk(TM) Linux(R) for their next generation COTS (Commercial-Off-the-Shelf)-based Unmanned Combat Air Vehicle (UCAV) simulation platform.

Alenia Aeronautica plans to use the high-performance iHawk(TM) multiprocessor systems as the real-time host and graphics system for the visual system for their next generation UCAV simulator. To reduce engineering time and labor costs, Alenia will utilize Concurrent's Linux based, NightStar(TM) tool kit, a standards-based set of real-time software development tools that enable system builders to maximize productivity in real-time application development. NightStar tools are specifically designed to allow integrators to intelligently identify problems early in the project life cycle - and correct them faster.

According to Warren Neuburger, Concurrent ISD president, "We are extremely pleased to be selected by Alenia Aeronautica, a recognized leader in the aerospace industry with a long-standing tradition of technology innovation." Neuburger added, "Alenia Aeronautica's engineering success in UCAV applications and its use of COTS-based products, including RedHawk real-time Linux as an alternative to more costly proprietary IG (Image Generation) solutions, is truly ground breaking."

iHawk systems are powered by one to eight Intel Pentium(R) Xeon processors, up to 4 GB of memory, and PCI I/O in rackmount and tower enclosures. iHawks are true symmetric multiprocessors that run a single copy of Concurrent's RedHawk Linux real-time operating system. In image generation applications, the iHawk 860 can be configured with a variety of NVIDIA(R) dual-monitor capable AGP (Accelerated Graphics Port) and PCI (Peripheral Component Interconnect) graphics controllers. Combined with popular 3D visualization software such as OpenGL(R), OpenSceneGraph, Vega Prime(TM) and GL Studio(TM), the iHawk is the ideal COTS based imaging platform for today's simulation, imaging and modeling applications.

RedHawk Linux provides fast response to external events, optimized interprocess communication, and high I/O throughput needed for time-critical applications. RedHawk Linux, compatible with the popular Red Hat distribution, has gained acceptance as a leading real-time Linux operating system for high-performance, mission-critical applications by customers throughout the world. Concurrent recently delivered the industry's first real-time Linux for the AMD Opteron(TM) processor for the development of next-generation, 64-bit real-time applications.
