ATLANTA--(BUSINESS WIRE)--March 6, 2001

PowerWorks(TM) Offers New Software Development Options

for Concurrent Users

Concurrent Computer Corporation (Nasdaq:CCUR), announced today the introduction of its PowerWorks Linux development environment (PLDE) based on the popular Linux(TM) open operating system. The new software environment, which began shipping at the end of February, will be demonstrated at the RTS 2001 conference in Paris, France, March 6-8 (Concurrent booth No. N19-020).

The PLDE allows users on a Linux PC or workstation to develop applications for any Concurrent PowerPC-based real-time computer system. The PLDE offers a convenient and economical way to utilize the extensive features of Concurrent compilers and real-time GUI tools. Application programs are compiled, linked, debugged, scheduled, and analyzed on a Linux PC while the user application executes on any system running Concurrent's PowerMAX OS(TM) real-time UNIX(R)-based operating system.

With the new PLDE, users now have the choice of developing their PowerMAX OS real-time applications on a Concurrent system or on a Linux PC. Recent acceptance of Linux as an alternative to the UNIX and Windows NT(R) operating systems were dominant factors in Concurrent's decision to introduce PLDE.

According to Paul Meyer, president of Concurrent's Real-Time Division, "Concurrent recognizes that our customers are very interested in having the flexibility of using the Linux operating system in solving their real-time needs. We now offer both PowerMAX OS and Linux for the development of applications requiring the deterministic, real-time performance available from PowerMAX OS. To date, we have completed the first phase of our real-time Linux development strategy and have seen favorable acceptance by the Fortune 500 companies currently evaluating our PLDE product around the world." He added, "Concurrent has always maintained a commitment to its customers to stay on the leading-edge of technology. With the addition of Linux as a development platform, we continue to provide the best and broadest real-time solutions available in the marketplace."

The PLDE includes high-performance C/C++ and Ada95 compilers together with Concurrent's powerful set of GUI real-time development tools - the NightView(TM) symbolic debugger, NightTrace(TM) real-time event analyzer, NightSim(TM) frequency-based scheduler for frame-based simulation. The PLDE also includes NightBench(TM), a common work environment for editors, compilers, and real-time tools. NightBench organizes all information required for consistent, repeatable generation of target applications while providing an efficient interface for editing, browsing, building, and real-time debugging.

With the PLDE, users can take advantage of the wide range of third-party software available for Linux systems. Developers can utilize their favorite configuration management and word-processing tools in developing real-time applications for Concurrent systems. The PLDE eliminates the need for a stand-alone development computer system and its user terminals. Developers can also employ Linux laptop PCs for application environments requiring secure, portable development.
