New Version of RedHawk Linux Offers Increased Real-Time Functionality and Performance

 

RedHawk Linux Release 5.1 Offers New Real-Time Functionality and
Performance 

New Features Include Non-Uniform Memory Performance Optimization 


Atlanta, GA - April 17, 2008 - Concurrent (NASDAQ:CCUR), a leading
provider of time-critical Linux(r) operating systems, integrated
software and computer solutions for mission-critical applications, today
announced that it has released a new version of its popular RedHawk(tm)
Linux real-time operating system, RedHawk Linux 5.1.  RedHawk Linux is
widely used in time-critical applications in simulation and training,
data acquisition, imaging, financial services and process control.
RedHawk guarantees that a user-level application can respond to an
external event in less than 30 microseconds. 

New features in RedHawk Linux 5.1 include:

*         Non-uniform memory architecture (NUMA) performance
optimization

*         2.6.23 Linux Kernel 

*         Full compatibility with Red Hat(r) Enterprise 5.1

*         Support for the latest Intel(r) and AMD(r) quad-core
processors and chipsets 

*         User-level (UIO) device driver support

*         The latest NVIDA graphics drivers optimized for real-time
performance 

*         New lockless kernel trace feature for enhanced real-time
debugging and performance analysis 

 

"Version 5.1 reinforces RedHawk as the leading Linux distribution for
hard real-time applications," said Vince Hauber, Sr. Product Manager,
Linux Systems for Concurrent.  "Our on-going support of emerging
technologies allows us to offer our customers the most cost-effective,
high-performance, real-time solutions."

 

RedHawk Linux 5.1 dramatically improves the determinism of real-time
processes in non-uniform memory architecture Opteron(tm)-based systems.
RedHawk ensures that all pages of a real-time process are local to a
given node and that no other process' pages are using that same node.
RedHawk can automatically duplicate libraries and other modules as
needed and maintain them simultaneously in multiple nodes to maximize
performance.

 

Support for the latest Intel and AMD quad-core processors and chipsets
provides for more computing power in smaller, more cost effective,
energy efficient packages than previously possible.  RedHawk 5.1
supports user-level (UIO) device drivers which allow developers to
implement a user-space, non-kernel driver for almost any type of
hardware.  RedHawk also includes the latest available NVIDIA graphics
driver specially optimized for real-time performance by Concurrent.  The
enhanced driver allows applications to achieve maximum determinism
during image rendering.

 

The performance of Concurrent's NightStar(tm) tools, a powerful
integrated package for developing time-critical Linux applications, has
been further enhanced by the introduction of RedHawk 5.1.  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. RedHawk 5.1's new
lockless kernel trace feature eliminates any contention when multiple
CPUs attempt to log trace points simultaneously.  This feature is
important as users scale up to systems with up to 32 cores.

 

RedHawk Linux is included with all Concurrent iHawk(tm) real-time
multiprocessors, ImaGen(tm) visual servers, MediaHawk(tm) Content
Delivery Systems and is also available as a software-only product.
Concurrent real-time platforms can be configured with up to 32 CPU cores
in one system chassis running a single copy of RedHawk Linux. 

 

RedHawk Linux has been deployed in hundreds of installations worldwide
including the U.S. Navy Aegis Open Architecture (AOA) CR2 program,
Airbus, Alcatel, Boeing, Ford Motor Company, Lockheed Martin, Northrop
Grumman, Toshiba TEC and many more.
