RedHawk 2.1 is billed as one of the most deterministic Linux operating system available today, supporting both 32bit Intel Xeon and 64bit AMD Opteron platforms in the same release. Based on the 2.6.3 Linux kernel, RedHawk 2.1 is compatible with the popular Red Hat Enterprise Linux distribution. It began shipping with Concurrent's iHawk COTS systems this month and is now in use by customers on Xeon and Opteron platforms developing 32 and 64bit real-time applications.
RedHawk 2.1 provides the same high performance level, API and user interface on Xeon and Opteron platforms, allowing customers the choice of processor families to suit their needs.
RedHawk incorporates all the standard Linux advancements provided by the 2.6.3 kernel such as significant file system performance improvements plus a wealth of Concurrent real-time enhancements.
Concurrent's refinements include kernel-level priority inheritance support, a frequency based scheduler (FBS), process and IRQ shielding extensions, user-level real-time hyper-threading control for Intel Xeon platforms, user-level spinlocks, significant real-time performance tuning and many additional improvements.
A prime example of RedHawk's real-time superiority is its guaranteed interrupt response time of less than 30us on a shielded processor.
RedHawk 2.1 on 32bit Xeon-based iHawks supports features such as user-level control of hyper-threading, which allows each physical CPU to be divided into two logical CPUs for more efficient processing.
On 64bit Opteron iHawks, users can run existing off-the-shelf 32bit applications, recompile 32bit RedHawk applications into 64bit mode for improved performance and extended addressing, as well as develop new 64bit applications on the same platform.
RedHawk 2.1 is designed to use the unique features of both processor families for maximum flexibility and performance.
RedHawk Linux on Concurrent's 32bit Intel Xeon powered iHawk systems has already proven itself in mission-critical programs throughout the world including the Eurofighter training device, FA-18 and EA-6B simulation systems and the Theater High Altitude Area Defense (THAAD) missile programme.
RedHawk is also used in telecommunications testing, US and European automotive simulation systems and industrial control applications.
"Concurrent's support for the Opteron platform allows us to address new high-tech markets, such as medical imaging, video encoding/decoding, and the financial industry that require larger memory addressing and increased processing power", said Gary Beerman, Concurrent Director of Marketing, Integrated Solutions Division.
"RedHawk 2.1 is available on iHawk COTS systems allowing our customers the choice of 32 or 64bit platforms that are best suited to their high-performance, mission-critical needs".
