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

NightStar Tools Offer a Comprehensive Environment for Developing

Real-Time Linux Applications on Concurrent

iHawk(TM) Multiprocessor Systems

Concurrent Computer Corporation (Nasdaq:CCUR), Real-Time Division, today announced the availability of its powerful set of NightStar(TM) real-time software development tools for Concurrent's new iHawk Intel(R)-based multiprocessor systems. The NightStar tools will be demonstrated with the iHawk at the International Training and Education Conference (ITEC) 2002 in Lille, France, April 9-11 - Concurrent booth #714. 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.

NightStar graphical tools allow users to debug, monitor, schedule, and analyze complex real-time applications typically found in simulation, data acquisition, and industrial control systems. NightStar tools enable system builders to reduce software development time and maximize productivity when developing real-time Linux solutions. The NightStar suite includes the NightView(TM) source-level debugger, the NightTrace(TM) event analyzer, the NightSim(TM) periodic scheduler, and the NightProbe(TM) data monitor. Each tool runs on an iHawk target system with minimum intrusion, thus maintaining the deterministic characteristics of the real-time application.

iHawk Intel-based multiprocessors run Concurrent's RedHawk(TM) Linux(R), a real-time version of the open source Linux operating system. RedHawk Linux provides fast response to external events, optimized interprocess communication, and high I/O throughput needed for mission-critical solutions. RedHawk Linux includes a multithreaded, fully preemptable Linux kernel with CPU shielding to maximize determinism and real-time performance. NightStar tools, together with RedHawk Linux, provide the most comprehensive development environment for complex real-time applications available to the Linux community.

"Our NightStar tools have long been popular with customers developing real-time applications on our VME-based platforms," said Rob Menzel, vice president of Worldwide Sales and Marketing, Concurrent Real-Time Division. "Users of our new iHawk PCI multiprocessors will have the same powerful development environment." He added, "In response to our customers' requests, we have added significant new features to the NightStar tool set. These enhancements will also be available on our VME platforms."

NightView is a source-level debugger that allows users to simultaneously debug multiple real-time processes. NightView provides the ability to change program execution and modify or retrieve data without stopping or interrupting the program. Breakpoints, watchpoints, and data monitorpoints are automatically patched into the application and execute at full application speed without effecting real-time deadlines. NightTrace is a graphical tool for analyzing the dynamic behavior of multiple real-time processes together with RedHawk Linux operating system activity. User-level tracing makes use of synchronized fast-access hardware clocks without system calls, thus trace information is logged in minimal time. NightTrace can also analyze distributed real-time applications executing on multiple systems.

NightSim is a tool for building and monitoring real-time applications that require predictable, cyclic process execution. Ideal for simulation applications, NightSim provides a graphical interface to the RedHawk Linux frequency-based scheduler. NightSim allows developers to control and dynamically adjust the execution of multiple coordinated processes, their priorities and CPU assignments. With NightSim, users can monitor the performance of their periodic applications by displaying period execution times, minimums, and maximums and can take action when frame overruns occur.

NightProbe is a graphical tool for monitoring, altering, and recording of program data within multiple executing real-time programs without significantly effecting their execution.

NightProbe can be used in a development environment as a tool for debugging, analysis, prototyping and fault injection, or in a production environment to create a GUI control panel for program input and output.

Linux application developers can save time and money using NightStar tools. Time-to-market can be greatly reduced due to the tools' robust features and easy-to-use, intuitive interface.

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.
