  • Rethinking Visual Cloud Workload Distribution
    WHITE PAPER Media and Communications Content Creation and Distribution RethinkingVisualCloud WorkloadDistribution Creating a New Model With visual computing workloads growing at an accelerating pace, cloud service providers (CSPs), communications service providers (CoSPs), and enterprises are rethinking the physical and virtual distribution of compute resources to more effectively balance cost and deployment efficiency while achieving exceptional performance. Visual cloud deployments accommodate a diverse range of streaming workloads, encompassing media processing and delivery, cloud graphics, cloud gaming, media analytics, and immersive media. Contending with the onslaught of new visual workloads will require more nimble, scalable, virtualized infrastructures; the capability of shifting workloads to the network edge when appropriate; and a collection of tools, software, and hardware components to support individual use cases fluidly. Advanced network technologies and cloud architectures are essential for agile distribution of visual cloud workloads. A 2017 report, Cisco Visual Networking Index: Forecast and Methodology, 2016–2021, projected strong growth in all Internet and managed IP video- related sectors. Compound annual growth rate (CAGR) figures during this time span, calculated in petabytes per month, included these predictions: • Content delivery network (CDN) traffic: 44 percent increase globally • Consumer-managed IP video traffic: 19,619 petabytes per month (14 percent increase) by 2021 • Consumer Internet video: 27 percent increase for fixed, 55 percent increase for mobile The impact of this media growth on cloud-based data centers will produce a burden on those CSPs, CoSPs, and enterprises that are not equipped to deal with TableofContents large-scale media workloads dynamically. Solutions to this challenge include: Creating a New Model . 1 • Increasingflexibilityandoptimizingprocessing: Virtualization and software- defined infrastructure (SDI) make it easier to balance workloads on available OpenSourceSoftware resources.

  • Intel® Quick Sync Video and Ffmpeg Installation and Validation Guide
    White paper Intel® Quick Sync Video and FFmpeg Installation and Validation Guide Introduction Intel® Quick Sync Video technology on Intel® Iris™ Pro Graphics and Intel® HD graphics provides transcode acceleration on Linux* systems in FFmpeg* 2.8 and later editions. This paper is a detailed step-by-step guide to enabling h264_qsv, mpeg2_qsv, and hevc_qsv hardware accelerated codecs in the FFmpeg framework. For a quicker overview, please see this article. Performance note: The *_qsv implementations are intended to provide easy access to Intel hardware capabilities for FFmpeg users, but are less efficient than custom applications optimized for Intel® Media Server Studio. Document note: Monospace type = command line inputs/outputs. Pink = highlights to call special attention to important command line I/O details. Getting Started 1. Install Intel Media Server Studio for Linux. Download from software.intel.com/intel-media-server- studio. This is a prerequisite for the *_qsv codecs as it provides the foundation for encode acceleration. See the next chapter for more info on edition choices. Note: Professional edition install is required for hevc_qsv. 2. Get the latest FFmpeg source from https://www.FFmpeg.org/download.html. Intel Quick Sync Video support is available in FFmpeg 2.8 and later editions. The install steps outlined below were verified with ffmpeg release 3.2.2 3. Configure FFmpeg with “--enable –libmfx –enable-nonfree”, build, and install. This requires copying include files to /opt/intel/mediasdk/include/mfx and adding a libmfx.pc file. More details below. 4. Test transcode with an accelerated codec such as “-vcodec h264_qsv” on the FFmpeg command line.

Abstract Processor architectures have been evolving quickly since the introduction of the central processing unit. For a very long time, one of the important means of increasing per- formance was to increase the clock frequency. However, in the last decade, processor manufacturers have hit the so-called power wall, with high heat dissipation. To overcome this problem, processors were designed with reduced clock frequencies but with multiple cores and, later, heterogeneous processing elements. This shift introduced a new challenge for programmers: Legacy applications, written without parallelization in mind, gain no benefits from moving to multicore and heterogeneous architectures. Another challenge for the programmers is that heterogeneous architecture designs are very different with respect to caches, memory types, execution unit organization, and so forth and, in the worst case, a programmer must completely rewrite the application to obtain the best performance on the new architecture.
