Qualcomm doubles down on its pivot to AI during Computex keynote

Qualcomm has announced it is shifting its focus from providing chips exclusively for communications devices and doubling down on its efforts to support AI workloads.The company is transitioning to becoming an “intelligent edge computing” firm, Alex Katouzian, a senior vice president at Qualcomm, said during a keynote speech at the Computex show in Taipei Tuesday.AI workloads require a lot of compute power and in February, Qualcomm announced the Snapdragon X75, its latest 5G modem component that the company said will be the world’s first modem-RF system for 5G-Advanced — a set of specifications designed to improve speed, maximize coverage, and enhance mobility and power efficiency for mobile devices. The X75 is also reportedly able to process AI workloads 2.5 times faster than its predecessor, the X70.To read this article in full, please click here

Inside Nvidia’s new AI supercomputer

With Nvidia’s Arm-based Grace processor at its core, the company has introduced a supercomputer designed to perform AI processing powered by a CPU/GPU combination.The new system, formally introduced at the Computex tech conference in Taipei the DGX GH200 supercomputer is powered by 256 Grace Hopper Superchips, technology that is a combination of Nvidia’s Grace CPU, a 72-core Arm processor designed for high-performance computing and the Hopper GPU. The two are connected by Nvidia’s proprietary NVLink-C2C high-speed interconnect.To read this article in full, please click here

Path Failure Detection on Multi-Homed Servers

TL&DR: Installing an Ethernet NIC with two uplinks in a server is easy¹. Connecting those uplinks to two edge switches is common sense². Detecting physical link failure is trivial in Gigabit Ethernet world. Deciding between two independent uplinks or a link aggregation group is interesting. Detecting path failure and disabling the useless uplink that causes traffic blackholing is a living hell (more details in this Design Clinic question).

Goodbye Twitter. It Was Fun While It Lasted

I joined Twitter in October 2008 (after noticing everyone else was using it during a Networking Field Day event), and eventually figured out how to automate posting the links to my blog posts in case someone uses Twitter as their primary source of news.

This week, I got a nice email from IFTTT (the solution I used) telling me they had to disable the post-to-Twitter applet. Twitter started charging for the API, and I was using their free service – obviously the math didn’t work out.

That left me with three options:

VPP MPLS – Part 4

VPP

About this series

Special Thanks: Adrian vifino Pistol for writing this code and for the wonderful collaboration!

Ever since I first saw VPP - the Vector Packet Processor - I have been deeply impressed with its performance and versatility. For those of us who have used Cisco IOS/XR devices, like the classic ASR (aggregation service router), VPP will look and feel quite familiar as many of the approaches are shared between the two.

In the last three articles, I thought I had described “all we need to know” to perform MPLS using the Linux Controlplane in VPP:

In the [first article] of this series, I took a look at MPLS in general.
In the [second article] of the series, I demonstrated a few special case labels (such as Explicit Null and Implicit Null which enables the fabled Penultimate Hop Popping behavior of MPLS.
Then, in the [third article], I worked with @vifino to implement the plumbing for MPLS in the Linux Control Plane plugin for VPP. He did most of the work, I just watched :)

As if in a state of premonition, I mentioned:

Worth Reading: Cargo Cult AI

Before we managed to recover from the automation cargo cults, a tsunami wave of cargo cult AI washed over us as Edlyn V. Levine explained in an ACM Queue article. Enjoy ;)

Also, a bit of a historical perspective is never a bad thing:

Impressive progress in AI, including the recent sensation of ChatGPT, has been dominated by the success of a single, decades-old machine-learning approach called a multilayer (or deep) neural network. This approach was invented in the 1940s, and essentially all of the foundational concepts of neural networks and associated methods—including convolutional neural networks and backpropagation—were in place by the 1980s.

The net’s long decline into “five giant websites, each filled with screenshots of the other four” isn’t a mystery. Nor was it by any means a forgone conclusion. Instead, we got here through a series of conscious actions by big businesses and lawmakers that put antitrust law into a 40-year coma.

My experiences in the War on Terror provided me with a glimpse of the AI revolution that is now remaking America’s political system and culture in ways that have already proved incompatible with our system of democracy and self-government and may soon become irreversible.

America has a monopoly problem. Most industries in the United States have consolidated in recent decades,1 and markups and profits have dramatically increased since around 1980.

If the fabric is error-free, and can send and receive between hosts at interface speed with no buffering or delay, a case can be made for a different kind of stream protocol, which implies perhaps less overhead per host to manage that stream of data.
