NightStar LX Debugging and Analysis Tools Reduce Test Time and Lower
Development Costs

Solutions Linux Booth/Paris La Defense #D15 

ATLANTA, GA - January 29, 2008 - Concurrent (NASDAQ:CCUR), a leading
provider of real-time Linux(r) operating systems, integrated software
and computer solutions for mission-critical applications, today
announced the release of a new version of its NightStar(tm) LX debugging
and analysis tools for Ubuntu Linux editions.  NightStar is a powerful,
integrated GUI tool set for developing and tuning time-critical
applications on x86-based platforms.  NightStar's advanced debugging
features enable system builders to solve difficult problems quickly.

The NightStar LX suite includes four tools -- the NightView(tm)
source-level debugger, the NightTrace(tm) event analyzer, the
NightProbe(tm) data monitor, and the NightTune(tm) system and
application tuner.  With this new release, NightStar LX now supports
platforms running Ubuntu desktop and server editions in addition to Red
Hat(r) Enterprise Linux and Novell(r) SUSE(r) Linux versions.  Ubuntu is
a desktop-oriented distribution based on Debian GNU/Linux.  Ubuntu
offers an up-to-date yet stable operating system, and features a strong
focus on user-friendliness, regular releases and ease of installation.

"Developing modern multi-threaded Linux applications on multi-core
architectures requires powerful debugging tools," said Gary Beerman,
Marketing Director, Concurrent.  "Troubleshooting and tuning in these
environments can be extremely challenging.  With NightStar, Linux
application engineers have exceptional visibility and control in both
the development and production environment."

NightStar tools run with minimal intrusion, thus preserving application
execution behavior and determinism.  Users can quickly and easily debug,
monitor, analyze and tune multi-threaded and parallel C, C++ or Fortran
applications in real-time.  An interactive memory debugger helps find
and eliminate memory problems during the debug process without code
recompilation. 

The NightView debugger offers many features not available in the gnu
debugger.  Users can debug multiple processes from a single session and
processes started from scripts.  While a process is executing, hot
patching can modify variables or add eventpoints.  Monitor points can
dynamically display expressions and variables.

NightStar is especially valuable in cases where the act of debugging may
change an application's behavior.  NightStar gives true visibility into
a running application providing a synchronized, time-based view of
events, states, data values and resource usage.  The NightTrace analyzer
allows users to display application behavior and performance, and
understand how threads interact with each other. 

NightStar LX features a Qt-based GUI with modern rendering, shading and
option control that makes it flexible and easy to use on multi-core
environments. NightStar LX allows individual tool panels to be moved and
resized so users can conveniently customize their debugging displays.

Pricing and Availability 

NightStar LX tools packages range from to $495 to $995. NightStar for
Ubuntu Linux will be available on March 1.  NightStar for Red Hat
Enterprise Linux and SUSE Linux is available for immediate trial
download and purchase.  NightStar is supported on both 32-bit and 64-bit
x86 platforms.  For further information and demo sign up please visit
