Booth #714

LILLE, France--(BUSINESS WIRE)--April 9, 2002

Concurrent Computer Corporation (Nasdaq:CCUR), Real-Time Division, today announced the introduction of its iHawk(TM) Series 860 high-performance Intel-based multiprocessors running the Linux(R) operating system. The new iHawk 860 will be demonstrated at the International Training and Education Conference (ITEC) 2002 in Lille, France, April 9-11 - Concurrent booth #714. To introduce the iHawk 860, Concurrent will also be hosting a noon press conference and luncheon on April 10 at the Lille Grand Palais in the Charles de Gaulle 1 room, second floor.

The new iHawk systems are powered by from one to eight Intel Pentium(R) Xeon(TM) processors with up to 32 GB of memory and PCI I/O in rackmount and tower enclosures. iHawk, an open systems real-time platform, is targeted to the simulation and training, data acquisition, and industrial control marketplace.

iHawk 860 systems offer the latest in integrated circuit and packaging technology. iHawks are true symmetric multiprocessors (SMP) that run a single copy of Concurrent's RedHawk(TM) Linux real-time operating system. All CPUs in a system are linked by a high-speed processor bus and have direct, cache-coherent access to all of main memory. The first customer shipments of iHawk are scheduled for July 2002.

According to Paul Meyer, president, Concurrent Real-Time Division, "Our customers are very interested in the option of using Linux in their real-time applications. The iHawk high-performance Linux PCI platform now joins our PowerMAX VME offerings in providing our customers extremely powerful solutions." He added, "Concurrent has always maintained a commitment to its customers to stay on the leading edge of technology. With the addition of iHawk, we continue to provide the best and broadest real-time solutions for mission-critical applications. Our long-term plans include both VME and PCI products."

iHawk 860 systems come in standard tower and rackmount enclosures with up to twelve 32/64-bit PCI slots for user I/O. iHawk workstation I/O options include high-performance AGP 3D graphics with OpenGL. For applications that require a VME I/O subsystem, an optional PCI-to-VME bridge and chassis is also available.

At the heart of each iHawk is the RedHawk Linux real-time operating system. RedHawk Linux provides the fast response to external events, optimized interprocess communication, and high I/O throughput needed for critical real-time applications. RedHawk Linux includes a multithreaded, fully preemptable Linux kernel with CPU shielding to maximize determinism and real-time performance. RedHawk is based on the popular Red Hat(TM) Linux and includes the entire Red Hat distribution content.

RedHawk Linux is a true real-time version of standard Linux. RedHawk provides a single programming environment for direct control of all system operations. Complex real-time applications often require that file I/O, networking, and graphics be controlled deterministically together with real-time tasks. Only RedHawk Linux's single-kernel design ensures this determinism.

iHawk systems also support Concurrent's powerful set of NightStar(TM) development tools. Users can schedule, monitor, debug, and analyze their real-time applications on iHawk multiprocessor systems or remotely from a desktop PC or laptop. Each tool runs on the iHawk target system in a non-intrusive manner, thus preserving the deterministic characteristics of the real-time application.

For optimal determinism, iHawk includes Concurrent's Real-Time Clock & Interrupt Module (RCIM), a multifunction PCI card designed for time-critical applications that require rapid response to external events. The RCIM allows multiple iHawk systems to be synchronized by a common clock source. The RCIM includes four programmable timers, and four input and four output external interrupt lines.

Concurrent's Professional Services Group is available to design and deliver iHawk systems for customers who require complete competitive solutions for demanding real-time applications. Concurrent engineers can provide special packaging including ruggedized peripherals and enclosures, integrate third-party I/O cards, develop and integrate Linux drivers, and perform application rehosting.

Now in its 13th year, ITEC is Europe's largest training and simulation show where the latest products, systems and services are exhibited to buyers and users from around the world. Military personnel from every European country, USA, Canada, and NATO visit the exhibition and network with their colleagues from other defense forces. In addition, visitors come to see and buy training technology for medicine, railways, space, emergency readiness, and business.
