Intel technologies’ features and benefits depend on system configuration and may require enabled hardware, software or service activation. Learn more at intel.com, or from the OEM or retailer.
Intel processors of the same SKU may vary in frequency or power as a result of natural variability in the production process.

The cost reduction scenarios described are intended to enable you to get a better understanding of how the purchase of a given Intel based product, combined with a number of situation-specific variables, might
affect future costs and savings. Circumstances will vary and there may be unaccounted-for costs related to the use and deployment of a given product. Nothing in this document should be interpreted as either a
promise of or contract for a given level of costs or cost reduction.

Optimization Notice: Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2,
SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel.
Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice. Notice Revision #20110804.
No computer system can be absolutely secure.
Intel® Advanced Vector Extensions (Intel® AVX)* provides higher throughput to certain processor operations. Due to varying processor power characteristics, utilizing AVX instructions may cause a) some parts to
operate at less than the rated frequency and b) some parts with Intel® Turbo Boost Technology 2.0 to not achieve any or maximum turbo frequencies. Performance varies depending on hardware, software, and
system configuration and you can learn more at http://www.intel.com/go/turbo.
Available on select Intel® processors. Requires an Intel® HT Technology-enabled system. Your performance varies depending on the specific hardware and software you use. Learn more by visiting

§ Configurations: The testing was done on Based on fourth-generation Intel Xeon E5-2699 v4 @2.20 GHz processor with 22 cores, 55 MB LLC and 62 GB memory 16 1G hugepages. The testing was conducted in
OPNFV Pharos testbed on Pod 12 by VSPERF community engineers

4. Why Clear Linux* OS?
*Other names and brands may be claimed as the property of others

5. Today’s operating systems are
required to meet new
expectations
PERFORMANCE SECURE CUSTOMIZABLE MANAGEABLE

6. Clear Linux* OS
is an open source rolling release Linux distribution
optimized for performance and security, from
the Cloud to the Edge, designed for
customization, and manageability.
*Other names and brands may be claimed as the property of others

7. Why Clear Linux* OS?
Delivering tuned performance of Intel features on
Linux across the entire OS stack.
A modular, cross architecture open source OS
providing customers the ability to differentiate.
Industry blueprint to incorporate Intel®
platform features and optimizations in
a single, performance-driven Linux
distribution.
Available at: Clearlinux.org
Clear Linux OS is supported and verified on most Intel platforms (32): https://clearlinux.org/documentation/clear-linux/reference/compatible-hardware

Optimizations

9. Performance throughout the stack
To get end user performance, optimization at all
layers is required
Clear Linux is highly tuned for Intel platforms
where all optimizations turned on by default
Clear Linux channels the best of Intel’s industry
leading kernel expertise to provide the highest
performing kernel for your OS.

11. Security
Clear Linux* OS stays in lockstep with upstream for current security
upgrades and is designed to deliver available security mitigations to
customers rapidly.

12. Modular for
Customization and Control

13. OS Design Principle: Easier Manageability
Clear Linux* OS employs the stateless
concept - a strict separation between User
and System files for easier OS manageability.
Traditional OS:
Content and data intermingled
Clear Linux OS:
Designed so that the user is able to quickly and easily manage
their custom configurations vs. system configurations.
This modularity allows for easier
manageability and simplifying
customization.

The Mixer Tool: Accelerating Customization
Allows for Incremental Effort
Build customer solutions on top of Clear Linux
easily with the Mixer
Don’t need to recompile entire OS, work is only
required on the customization piece

Intersection point when a new release is happening -
Mixer takes latest Clear release and adds it to the load line
and then takes any custom package if available
With Mixer there is no need to
engage with Clear Linux OS
