Concurrent Adds Value with Mathwork Products Option for iHawk Systems

8/11/2004 - Concurrent Computer Corporation (NASDAQ: CCUR), Integrated Solutions Division, announced it has signed a value-added reseller agreement with The MathWorks, Inc. Concurrent has teamed with The MathWorks, the leading provider of technical computing and model-based design software, to deliver a comprehensive, integrated platform for complex simulation, rapid prototyping and hardware-in-the-loop testing.

The reseller agreement leverages the strengths of both companies’ products. Concurrent iHawkTM systems are high-performance Xeon and Opteron-based multiprocessors that run Concurrent’s RedHawkTM Linux®, a real-time version of the open source Linux operating system. Concurrent iHawk customers can now purchase the primary MathWorks products for Model-Based Design – MATLAB®, Simulink®, Stateflow®, and Real-Time Workshop® – directly from Concurrent with their iHawk systems.

MATLAB includes mathematical functions, visualization and a powerful language to provide a flexible environment for technical computing. MATLAB makes it easy to explore data, create algorithms and create custom tools. Simulink is an interactive tool for modeling, simulating and analyzing dynamic, multi-domain systems. Simulink allows a user to accurately describe, simulate, evaluate and refine a system's behavior through standard and custom block libraries. Using the Real-Time Workshop product, code can be automatically generated from Simulink models for use in Concurrent’s iHawk real-time systems. MATLAB and Simulink are used in a wide range of applications including control systems design, digital signal processing, communications, test and measurement, and image processing.

For complex modeling applications, Concurrent offers its optional RT-LAB RLX software environment, which allows users to easily set up and execute multiprocessor simulation, rapid prototyping and hardware-in-the-loop testing. The Simulink, Stateflow and Real-Time Workshop products now work directly with RT-LAB RLX to provide a powerful, fully-integrated solution for distributed, multiprocessor, multi-rate simulation. The flexibility of RT-LAB RLX integrated with MathWorks products can be applied to the most complex simulation and control problems, dramatically speeding up test system implementation and reducing costs.

“We’ve developed an interface to MathWorks products with the modeling and simulation engineers in mind. Users of MathWorks best-in-class modeling suite can now enjoy the advantages of Concurrent’s real-time hardware and software products,” said Ken Jackson, vice president of Business Development, Concurrent Integrated Solutions Division.

“We are pleased to reach this agreement with Concurrent, a recognized leader in providing real-time solutions, to serve our common customers around the world,” said Jim Tung, MathWorks Fellow at The MathWorks. “The availability of RT-LAB RLX on iHawk reinforces Simulink as the leading platform for Model-Based Design, and is a welcome addition to our Connections Program.”

Concurrent’s RT-LAB RLX is fully integrated with Simulink and enables real-time execution of dynamic system and mathematical models on one or more distributed targets. RT-LAB RLX automatically prepares models for real-time execution. Using a simple six-step GUI, engineers can select a Simulink model, assign subsystems to specific target nodes, transparently perform code compilation, establish inter-node communications, and assign signal I/O.

RT-LAB RLX provides a special blockset for Simulink 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. RT-LAB RLX also fully supports the MathWorks Stateflow product in this process.
