Concurrent and Opal-RT Introduce Simulation Platform for iHawk Linux

12/4/2003 - Concurrent Computer Corporation (NASDAQ: CCUR), Integrated Solutions Division, and Opal-RT Technologies Inc. (, a leader in distributed simulation on PC-based platforms, announced the development of RT-LAB RLX for Concurrent’s RedHawkTM real-time Linux® operating system. With this development, Opal-RT extends its PC-based real-time simulation platform for use on Concurrent’s iHawkTM Linux systems, providing the design engineer with a scalable, high-performance real-time environment that utilizes commercial off-the-shelf (COTS) technologies to deliver hard-real-time simulations from complex dynamic models developed in The MathWorks' Simulink® and National Instruments' MATRIXx. RT-LAB RLX is being previewed at the Interservice/Industry Training, Simulation and Education Conference (I/ITSEC) the first week of December in Orlando, Florida, Concurrent Booth # 511.

“As a firmly established leader in the development of high-performance real-time technologies for both government and industry applications, Concurrent Computer Corporation is an ideal company for Opal-RT to partner with to further extend the reach of the RT-LAB platform,” said Paul Goossens, Opal-RT Technologies vice president of Marketing. “This combination will now allow the growing number of design engineers who make Linux their preferred OS to further shorten the overall design process of complex systems.”

RT-LAB RLX revolutionizes the engineering process in system design. Its power and flexibility can be applied to the most complex simulation and control problems, dramatically speeding up test system implementation. RT-LAB RLX automatically prepares complex models for real-time execution. Using a simple six-step GUI, engineers can select a Simulink or SystemBuild model, assign subsystems to specific target nodes, transparently perform code compilation, establish inter-node communications and assign signal I/O.

Ken Jackson, Concurrent’s vice president of Business Development, Integrated Solutions Division, stated, “Opal-RT has steadily developed a reputation as the industry’s leading developer of high-performance, high fidelity software for conducting hardware-in-the-loop testing of complex control systems. We are excited about the development of RT-LAB RLX for Concurrent’s RedHawk real-time Linux operating system and believe this product, when released, will greatly expand the tool set available for design engineers focused on either man-in-the-loop or hardware-in-the-loop simulation.”

RT-LAB RLX supports a wide range of run-time configurations from a single-platform host/target to a complex network of target systems controlled from a single host. RT-LAB RLX provides tools for running highly complex models on a dual, quad or 8-processor iHawk or a network of distributed iHawks using ultra low-latency communications to achieve the required performance. RT-LAB RLX iHawk target systems can be hosted by RT-LAB software running on an iHawk host with RedHawk Linux or a Windows® PC.

RT-LAB RLX is tightly integrated with the Simulink modeling environment. A model developed in Simulink can be executed in real-time on one or more distributed targets. RT-LAB RLX provides a special blockset to prepare the model for distributed processing, inter-node communication and signal I/O. Once a model has been prepared, RT-LAB RLX uses Real-Time Workshop® to convert separated components into C code for compilation on each target processor.

In addition, RT-LAB RLX is fully compatible with the MATRIXx product family – Xmath, SystemBuild and AutoCode.

RT-LAB RLX takes full advantage of Concurrent iHawk symmetric multiprocessors with up to eight Intel® Xeon® processors per system running the RedHawk Linux real-time operating system. The iHawk is a high-performance PCI-based computer platform especially designed for real-time data acquisition, simulation and industrial systems applications.

Compatible with the popular Red Hat® Linux distribution, RedHawk features high I/O throughput, fast response to external events, and optimized interprocess communication. RedHawk's multithreaded, fully preemptible Linux kernel with low-latency enhancements make it the ideal Linux environment for complex modeling applications. RedHawk's true symmetric multiprocessing support includes load-balancing and CPU shielding to maximize determinism and real-time performance in RT-LAB RLX target execution.

RT-LAB RLX is scheduled for general availability in Q1 of 2004.
