New version of Concurrent NightStar Tools for Linux

Concurrent's NightStar Tools For Linux To Offer New Graphical Interface
and Enhanced Real-Time Application Debugging And Tuning

NightStar 4.1 Includes Improved GUI Control and Application Illumination
Feature For Increased Programmer Productivity


Concurrent  ITEC Booth #516

Duluth, GA - April 18, 2007 - Concurrent (NASDAQ:CCUR), a leading
provider of time-critical Linux(r) operating systems and integrated
software and computer solutions for mission-critical applications, today
announced that it will soon offer a new version of its popular NightStar
(tm) integrated software tool set.  NightStar is widely used for
debugging and analyzing time-critical applications running on Concurrent
real-time Linux operating system distributions RedHawk(tm) Linux(r) and
SUSE(r) Linux Enterprise Real Time from Novell(r).

NightStar version 4.1 features a complete graphical user interface (GUI)
makeover that makes it more flexible and easier to use.  NightStar's
current Motif GUI will be replaced by a Qt-based presentation with more
modern rendering, shading and option control.  The new version allows
individual tool panels to be moved and resized to make it easy for users
to customize their debugging displays.

"The features we've added to NightStar, including the new Qt GUI ,
continue Concurrent's tradition of offering the most advanced yet
easy-to-use debugging environment for troubleshooting and tuning complex
Linux software applications," said Vince Hauber, Concurrent Senior
Product Manager.  "This is the very reason why major programs such as
the U.S. Navy's Aegis Combat System continue to be longstanding
NightStar users."

The NightStar suite includes the NightView(tm) source-level debugger,
the NightTrace(tm) event analyzer, the NightProbe(tm) data monitor, the
NightSim scheduler and the NightTune(tm) system and application tuner.  

Key new features include:

*          NightTrace event analyzer's Application Illumination feature,
empowering programmers with automatic trace application function calls
and the ability to examine parameters passed and returned.  Application
Illumination is customizable and can provide a complete view of glibc
activities;  

*          Enhanced NightProbe data monitor providing live browsing,
modification and graphical display of variables;

*          NightTune tuner detailed display of system memory usage,
presenting a new set of process statistics such as virtual memory and
file descriptor usage and environment variables.

NightStar is Concurrent's powerful, integrated tool set for developing
and analyzing time-critical applications. NightStar tools run with
minimal intrusion, thus preserving application execution behavior and
determinism.  Users can quickly and easily debug, monitor, schedule,
analyze and tune applications in real-time.

NightStar 4.1 will be generally available June 2007.

Technical experts from Concurrent (Booth #516) will be available to
answer questions on NightStar 4.1 and other Concurrent solutions at the
ITEC 2007 Conference and Exhibition, Europe's premier Defence Training,
Education and Simulation conference, being held April 24-26, 2007 in
Cologne, Germany.
