Tame your Work Flow

This week we begin Part 2 of  Daniel Doiron and Steve Tendon’s Tame your Work Flow. Part 2 transitions us from improving wait time and flow efficiency and begins a deep dive into the Theory of Constraints (ToC). The authors use the metaphor of an Archimedean lever to point out that in order to make major changes you need a fixed point or fulcrum and a big lever. In process improvement, the constraint is that point where a lever can be inserted to make change happen. The problem in knowledge work is that it is hard to identify the constraint. 

Chapter 5, Where to Focus Improvement Efforts has several important definitions. For example, the definitions of constraint and bottleneck. For the longest time, I struggled with the difference between the two. Several years ago Steve Tendon set me right during a conversation on the Software Process and Measurement Cast. I will use a real-life, unfortunate but true, example to illustrate the nuances in concepts in Chapter 5.

The example: I worked with an organization that had a team (many of the teams had problematic structures) that consisted of three business analysts (BAs), one coder, and part of a tester. The team worked on small enhancements and user complaints/bugs. Everybody was pushed to work full blast on things that were in their individual span of control (BAs writing requirements, coders coding, and testers testing) and then throw it over the wall to the next person in the process. The BAs were always piling work on the coder and the coder was always tossing more work on the tester that was addressable.  

It was decided that fixing the organization structure by repurposing a BA as a tester would cause too much upheaval. In the book, Daniel and Steve point out that “Changing the way work is performed (acting on Touch Time) is always an expensive proposition and has a huge risk of failure.” It was easier to begin to build trust in changing the process by driving out wait time. As we noted in Chapter 4, reducing wait time is cheap and has a very low risk. While flow efficiency improved, work still piled up in front of the coder and the tester.  

The flow had two bottlenecks. The authors define a bottleneck as “any kind of resource that cannot deliver up to the demand that is placed on it.” Coder and tester in this circumstance. The push to go full blast and only focus on your specialty ensured that no one did much to help anyone else out. Once we had improved wait time and built some trust that change was not a dirty word, work restructuring finally became an option. The issue was that we would only have one shot if things went wrong. Finding the constraint was critical.

The operational definition of a constraint in the book that I find most useful is that the constraint is the bottleneck (out of possibly many) that has the least Capacity or longest

NVIDIA GeForce RTX 30 Gaming Laptops Powered Massive Cryptocurrency Mining Farm Spotted in China, Over Hundreds of Ampere Laptops

Last week, it was reported how cryptocurrency miners are rushing after NVIDIA GeForce RTX 30 Gaming Laptops to earn that sweet digital currency profits. Well, now a video tour of one of the mining farms has surfaced showcasing several hundred gaming laptops being used to mine the cryptocurrencies.

Several Hundred NVIDIA GeForce RTX 30 Gaming Laptops Spotted In Chinese Cryptocurrency Mining Farm Video Tour

Earlier, we only got to see a glimpse of the cryptocurrency mining farm but a brand new video has surfaced which shows the complete scale of the setup. The setup is based in China but the user has not mentioned the location for obvious reasons. As you can tell, the mining farm is set up with and utilizes NVIDIA GeForce RTX 30 Gaming laptops from the Chinese manufacturer, Hasse.

The Hasse laptop is based on the GeForce RTX 3060 mobility GPU. The GeForce RTX 3060 laptop solution is definitely not similar to the desktop variant which offers much better specifications and doesn’t come at a lower price either. According to NVIDIA themselves, the RTX 3060 laptops start at $999 US & the miners can save a penny by purchasing in bulk but they end up paying at least $600 US more for the laptop variant. Plus, they also end up with unnecessary hardware that the laptops feature. At the same time, the laptop variants do feature reduced TGPs which might save electricity costs & offer higher cryptocurrency mining rates.

What’s interesting here is that the user has bought these laptops in a bulk order which means that either the retailer, distributor, or the manufacturer itself is openly supporting cryptocurrency miners over actual customers such as gamers which these laptops are primarily designed for. The selling party could be taking advantage of crypto miners by selling these at scalped prices to earn a profit.

A couple of rumors regarding Intel’s Ice Lake-SP Xeon server CPUs have surfaced over the web, mostly from known leaker, Momomo_US. The information consists of specifications, configs & power ratings of several SKUs that will be part of the 3rd Gen Xeon Scalable processor family.

Intel 3rd Gen Ice Lake-SP Xeon CPU Rumors Point Out Up To 40 Cores, 270W TDPs & Brand New Core Architecture

Starting off with the details, Intel’s 3rd Gen Ice Lake-SP Xeon CPUs will be based on the 10nm+ process node and utilize the Sunny Cove core architecture. The Intel Sunny Cove x86 architecture has been around since 2019 and was first featured on Intel’s 10th Gen Ice Lake processors for the notebook segment. Intel has since moved over to Tiger Lake which is based on the Willow Cove x86 architecture and makes use of the 10nm SuperFin process node.

Some of the major upgrades that Intel’s 10nm+ for Ice Lake-SP Xeon CPU will deliver include:

2.7x density scaling vs 14nmSelf-aligned Quad-PatterningContact Over Active GateCobalt

Intel’s Raja Koduri Teases Xe HPG Enthusiast Gaming Graphics Cards In Action Within 3DMark Mesh Shader Test, Launch Imminent?

Intel’s Senior Vice President, Raja Koduri, has been dropping some major bombs on his Twitter feed for a while now. The most recent one being the Xe HPC chip shot which is an engineering marvel but it looks like Raja has switched gears and now dropped a teaser of Intel’s first gaming discrete graphics cards, the Xe HPG.

Intel Teases Xe HPG Enthusiast Gaming Graphics Cards, Running 3DMark’s Upcoming Mash Shader Feature

It’s been some time since we last heard about Intel’s Xe HPG (High-Performance Gaming) discrete GPUs or graphics cards. Intel’s main focus has been Xe-LP and they also dive in deeper within the tech that Xe HPC has to offer considering it’s their biggest chip design to date and the flagship Xe product. But the Xe HPG is where the gaming community is more focused at and we have got the first teaser of Intel’s discrete graphics cards based on the HPG GPUs running in action.

The teaser from Raja shows an undisclosed Intel Xe HPG GPU based discrete graphics card running the UL 3DMark Mesh Shader Feature test. This test is coming out soon and will be integrated within the 3DMark test suite. Mesh Shader is one of the major features introduced within DirectX 12 Ultimate API back in 2020. The feature is supported by NVIDIA’s Turing, Ampere, and AMD’s RDNA 2 graphics architectures. Based on this tweet, Intel will also be adding Mesh Shaders support on its Xe-HPG class discrete GPUs.

The technology helps to dramatically improve performance and image quality when rendering a scene with a substantial number of very complex objects. Take for instance a very complex & triangle-heavy mesh and what Mesh Shaders would essentially do is segment it into smaller meshlets. Each meshlet ideally optimizes the vertex re-use within it. Using the new hardware stages and this segmentation scheme, devs can render more geometry
