Ensure critical business processes complete in time, each and every time, and deliver high quality of service, even under heavy system loads.
Timing is everything. In some cases, predictability of response times is even more important than absolute speed. Even more important than how fast it takes for a process or application thread to execute, is making sure that it takes the exact same time to complete, each and every time.
Certain process control applications, computer simulations, and high performance risk management algorithms require the precise synchronization of intermediate execution threads in order for the system as a whole to function properly. You can get better performance from these time sensitive applications, through greater predictability, when you use SUSE Linux Enterprise Real Time Extension.
The ability of SUSE Linux Enterprise Real Time Extension to shield or "reserve" key system resources for high priority processes, together with its preemptible real time kernel, is what ensures greater predictability of your time-sensitive mission-critical applications. You can be confident that your time-critical applications do not experience resource contention, or unwanted process interrupts that could contribute to increased variability in response and execution times.
SUSE Linux Enterprise Real Time Extension includes enhancements to the real-time scheduler and locking mechanisms, which enhance performance while maintaining predictability. The spinlocks in SUSE Linux Enterprise Real Time Extension have been modified to reduce operating system context switching times, dramatically improving the performance of throughput sensitive workloads.
A new adaptive locking algorithm for kernel locks allows tasks to wait in a preemptible manner, instead of immediately releasing the CPU when waiting on a contended resource. These adaptive locks effectively decrease the number of context switches on the system, increasing throughput while simultaneously decreasing latency for certain applications.
SUSE Linux Enterprise Real Time Extension 11 Service Pack 3 includes the latest hardware enablement introduced with SUSE Linux Enterprise 11 Service Pack 3. And it includes other important updates such as LTTng (both kernel and user interface) to deliver the maturing community projects.
