Operating systems The choice of operating system is a key decision in low-latency applications. General purpose operating systems such as SUSE Linux Enterprise Server, Red Hat Enterprise Linux, and Microsoft® Windows Server® are designed so that some operating system processes cannot be interrupted once started. Operating systems that are designed for real-time, low-latency applications are designed to permit some operating system processes to be interrupted by the critical application. This guarantees that the critical application has the resources necessary without interruption from the operating system. Ret Hat Enterprise MRG Red Hat Enterprise MRG is a next-generation IT infrastructure incorporating Messaging, Realtime, and Grid functionality. MRG's realtime kernel provides the highest levels of predictability for consistent lowlatency response times to meet the needs of time-sensitive workloads. For more information about Red Hat Enterprise MRG, see the Red Hat MRG website (http://www.redhat.com/mrg/realtime/). SUSE Linux Enterprise Real Time Extension SLERT is an enhanced version of SUSE Linux Enterprise Server that provides reduced latency and predictable performance in critical, time-sensitive applications. For more information about SLERT, see the SLERT website (http://www.novell.com/products/realtime/). HP support for real-time operating systems Tuning the operating system is critical and is dependent on application characteristics. HP works with realtime operating system vendors to ensure compatibility with HP servers and server blades. For more information, see the HP Realtime Linux website (http://www.hp.com/go/realtimelinux/). Operating systems 5
