Concurrent has revised its real-time Linux distribution for single- and multi-processor Intel Xeon and AMD Opteron platforms. RedHawk 2.2 is based on a 2.6.6 Linux kernel, and adds support for Xeon EM64T (Nocona) chips. The company also launched a worldwide channel program yesterday, and is seeking resellers and manufacturing partners.

RedHawk 2.2

RedHawk 2.2 supports single- and multi-processor systems based on 64-bit AMD Opteron processors, as well as 32- and 64-bit Intel Xeon processors. It provides the same interface on both Xeon and AMD systems, Concurrent says.

RedHawk 2.2 is based on Linux 2.6.6, and takes advantage of 2.6.6 features such as file system performance improvements and a preemptive, multithreaded, reentrant kernel, according to Concurrent.

RedHawk 2.2 also includes real-time enhancements developed by Concurrent, which the company lists as: shielding on a per-CPU basis, priority inheritance, minimal dispatch latencies, cross-processor interrupt reduction, user-level real-time Hyper-Threading control, non-preemptible spin locks, and more. On shielded processors, RedHawk 2.2 delivers an interrupt response time under 30 microseconds, the company says.

Concurrent says it has shipped RedHawk 2.2 since October, on COTS (commercial off-the-shelf) systems with single- and multiple 32-bit and 64-bit processors. The company says its RedHawk powered iHawk systems (pictured) are suitable for mission-critical applications, and are used in the C-17 aircraft program, Eurofighter training systems, submarine sonar simulation and testing, air-traffic control systems, and in the THAAD (Theater High Altitude Area Defense) missile program. Other applications include telecommunications testing, music simulation research, US and European automotive simulation systems, and industrial data acquisition and control applications such as wind tunnel testing.

Channel program

Concurrent says it is actively seeking reseller relationships with VARs (value-added resellers), OEMs (original equipment manufacturers), and distributors, through a worldwide channel partner program launched yesterday. It hopes to broaden its presence in the financial and medical markets, among other new business sectors.
