Machine Learning Goes Deeper with Intel Xeon Phi Processors

CIOReview Team | Monday, 26 September 2016, 05:52 IST

Machine learning implementations require an enormous amount of compute power to run mathematical algorithms and process huge amounts of data. With these challenges in mind, Intel has expanded its range of technologies for machine learning with the release of the Intel® Xeon Phi™ processor family. The Intel® Xeon Phi™ processoroffers robust performance for machine learning training models, and with the flexibility of a bootable host processor, it is capable of running multiple analytics workloads.Intel® Scalable System Framework-based clusters powered by the Intel Xeon Phi processors and available integrated Intel® Omni-Path Architecture, enable data scientists to run complex neural networks and run training models in significantly shorter time. In a 32-node infrastructure, the Intel Xeon Phi family offers up to 1.38 times better scaling than GPUs and in a 128-node infrastructure, the time to train models can be completed up to 50 times faster using the Intel Xeon Phi family3.

The Intel Xeon Phi family is complemented by the Intel® Xeon® processor E5 family, the most widely deployed infrastructure for machine learning4. Intel Xeon processor E5 v4 product family is well suited for machine learning scoring models and provides great performance and value for a wide variety of data center workloads. Together, these Intel Xeon processor families offer developers a consistent programming model for training and scoring and a common architecture that can be used for high-performance computing, data analytics and machine learning workloads.

Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors. Performance tests, such as SYSmark and MobileMark, are measured using specific computer systems, components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products.

Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. 

Intel technologies’ features and benefits depend on system configuration and may require enabled hardware, software or service activation. Performance varies depending on system configuration. No computer system can provide absolute security. Cost reduction scenarios described are intended as examples of how a given Intel- based product, in the specified circumstances and configurations, may affect future costs and provide cost savings.  Circumstances will vary. Intel does not guarantee any costs or cost reduction.

All dates and products specified are for planning purposes only and are subject to change without notice.

Relative performance for each benchmark is calculated by taking the actual benchmark result for the first platform tested and assigning it a value of 1.0 as a baseline. Relative performance for the remaining platforms tested was calculated by dividing the actual benchmark result for the baseline platform into each of the specific benchmark results of each of the other platforms and assigning them a relative performance number that correlates with the performance improvements reported.
