"Using the Solaris Operating System to Optimize the Xeon Processor 5500 Series CPUs*" is a paper by several hands whose intent is to serve as a quick reference guide for developers and system administrators that want to optimize the Solaris OS on the Intel Xeon processor 5500 series platform.
The paper includes a short overview of the Sun and Intel collaboration, and brief technical descriptions of specific features and capabilities that can be implemented in the Solaris OS to optimize the specific capabilities of Intel Xeon processor 5500 series systems, specifically in the areas of:
- Intelligent performance: NUMA and Multi-threading; Performance Counters on Solaris
- Automated energy efficiency: Power Aware Dispatcher; PowerTOP for OpenSolaris
- Reliability and availability: Fast Reboot; Support for Microcode Updates on Intel Processors
- Developer tools: Utilizing New Processor Instructions with the Solaris OS; Improved Microvectorization and Automatic Parallelization; Instruction Selection; OpenMP Development with Sun Studio
"Sun and Intel, as part of a broad strategic alliance, have been working togetherfrom design and architecture through implementationto ensure that the Solaris OS is optimized to unleash the power and capabilities of current and future Intel Xeon processors at the time of launch. Sun and Intel have made significant advances to optimize the Solaris OS for Intel Xeon processor-based systems, and are working closely to unleash new capabilities that are part of the Intel Xeon processor 5500 series. Engineering teams from the two companies are collaborating on optimizing how the Solaris ecosystem and the Intel Xeon processor 5500 series work together, with compelling results, including:
- Increased performance as the Solaris OS takes advantage of Intel multi-core processor capabilities and Intel Turbo Boost Technology.
- Optimized power efficiency and utilization by enabling Solaris to take advantage of Intel Xeon processor 5500 series performance-enhanced dynamic power management capabilities.
- Extending Predictive capabilities to improve reliability by incorporating Intel Xeon processor 5500 series features into the Solaris Fault Management Architecture (FMA)."
