SUSE Linux Enterprise Real Time Extension

Lower Latency

Agile firms that can respond more quickly to new information and changing market conditions have a distinct advantage over those that cannot. Running their time sensitive mission critical applications using SUSE Linux Enterprise Real Time Extension reduces process dispatch latencies, and gives firms the time advantage they need to make more money or avoid further financial losses, ahead of their competitors.

The Real Time Extension achieves these lower latencies with a preemptible real time kernel, together with the ability to identify which specific application threads are high priority processes. The incorporation of high resolution timers in the real time kernel allows for more fine grained measurement of time slices, further enabling lower latency. In this real time environment, user specified processes can be assigned the highest priority, ensuring that they will execute without delay, ahead of other system processes. Neither will they be interrupted by other system processes, including things like spinlocks and hard and soft interrupts, which once started, are not interruptible in general purpose operating systems.
