Better Gaming with HDMI 2.1 using VRR, QMS, QFT, ALLM

Posted by Charbax – February 10, 2018

HDMI 2.1 Specification Supports a Range of Features for Enhanced Gaming:
- Variable Refresh Rate (VRR) reduces or eliminates lag, stutter and frame tearing for more fluid and better detailed gameplay.
- Quick Media Switching (QMS) for movies and video eliminates the delay that can result in blank screens before content is displayed.
- Quick Frame Transport (QFT) reduces latency for smoother no-lag gaming, and real-time interactive virtual reality.
- Auto Low Latency Mode (ALLM) allows the ideal latency setting to automatically be set allowing for smooth, lag-free and uninterrupted viewing and interactivity.

48Gbit/s HDMI 2.1 cable, up to 10K120

Posted by Charbax – February 10, 2018

HDMI 2.1 Specification Supports Ultra High Speed Bandwidth Up to 48Gbps enabling Higher resolutions and faster refresh rates including 8K60Hz and 4K120Hz and support for resolutions up to 10K120 compressed. The Ultra High Speed HDMI Cable supports 48Gbit/s bandwidth for uncompressed HDMI 2.1 feature support and has very low emissions of Electromagnetic interference (EMI).

Dynamic HDR with HDMI 2.1, Technicolor Advanced Dynamic HDR

Posted by Charbax – February 10, 2018

Dynamic HDR support ensures every moment of a video is displayed at its ideal values for depth, detail, brightness, contrast and wider color gamuts. Here this interview is with Technicolor about their implementation of Dynamic HDR supported as part of the new HDMI 2.1 Spec.

eARC with HDMI 2.1, Enhanced Audio Return Channel at up to 40mbit/s

Posted by Charbax – February 10, 2018

eARC in HDMI 2.1 simplifies connectivity and supports the most advanced audio formats such as object-based audio, such as Dolby Atmos and DTS:X, highest audio quality, and ensures compatibility between audio devices and upcoming HDMI 2.1 products, enabling to deliver those formats via an eARC-enabled HDMI port on a future HDMI 2.1 TV. eARC also provides support for the TV’s over-the-air tuner, streaming apps received by the TV, and audio from HDMI sources connected to the TV.

A key advantage of eARC is that it enables a TV-centric living room or home theater configuration that can provide a more seamless experience. Today, an AV receiver—or a similar repeater device—is necessary to extract high quality audio from an HDMI link, while the video is processed and passed through to the TV. The user may have to switch inputs on both the TV and an audio device to find the source of their content, and content sourced within the TV and from TV inputs is frequently limited to stereo or, in the best case, one of a very small number of compressed formats.

With eARC, it will be possible to connect all sources through the TV and send audio to the sound system completely uncompromised. Furthermore, eARC will make possible a new breed of audio-only receivers that will yield greater value and ease-of-use by eliminating a video subsystem. So, in theory anyway, overall video and audio performance will improve with eARC.

Mont-Blanc ARM Supercomputer with the Barcelona Supercomputing Center (Next-gen ecosystem)

Posted by Charbax – February 5, 2018

Filippo Mantovani updates the audience of the GoingArm workshop at SC17 about the contributions of the Barcelona Supercomputing Center to the European Project Mont-Blanc.

Since 2011, Mont-Blanc pushes the adoption of Arm technology in the High Performance Computing deploying Arm-based prototypes, enhancing system software ecosystem and projecting performance of current systems for developing new, more powerful and less power hungry HPC computing platforms based on Arm SoC.

In the talk Filippo introduces the last Mont-Blanc system, called Dibona, designed and integrated by the coordinator and industrial partner of the project, Bull/ATOS. He also talks about tests performed at BSC of the Arm software tools (HPC compiler and mathematical libraries) as well as the Dynamic Load Balancing (DLB) technique and the MUltiscale Simulator Architecture (MUSA).

You can check out the Mont-Blanc and the BSC channels to know more about the research topics of this talk.

Mellanox ConnectX-5 Interconnect showcased on Qualcomm Centriq 2400 Data Center Platform

Posted by Charbax – February 1, 2018

At SC17, Qualcomm and Mellanox jointly showcase super-fast 100 Gb/s networking card Mellanox ConnectX-5. This Arm-based solution is enabled and ready for the most demanding compute and storage workloads on the Qualcomm Centriq 2400, the world’s first 10nm server processor.

Qualcomm Centriq 2400 Arm Server presentation at the Supercomputing SC17 ARM User Group Meeting

Posted by Charbax – February 1, 2018

Qualcomm Centriq 2400 processor, based on the Qualcomm Falkor CPU, QDT’s own Armv8-based custom CPU core design, delivers leading-edge aggregate performance, the world’s first and only 10nm server processor. The Qualcomm Centriq 2400 processor delivers a phenomenal performance-per-dollar. With a list price of $1,995, the 48-core Qualcomm Centriq 2460 processor delivers 4X better performance-per-dollar versus Intel’s highest-performance Skylake processor, the Intel Xeon Platinum 8180. With a list price of $1373, the 46-core Qualcomm Centriq 2452 processor offers 3X better performance-per-dollar versus Intel Xeon Gold 6152. And, with a list price of $888, the 40-core Qualcomm Centriq 2434 processor offers 2X better performance-per-dollar versus Intel Xeon Silver 41166. Qualcomm Centriq 2400 delivers 2.5x better performance per watt than competing x86 server processor running the same SPECint_rate2006 benchmark.
