Does Meeting Overhead Scale In Scrum?

Is a baby just a scaled down adult?

One of the most common complaints about using Scrum is the amount of meeting time.  In How Much Meeting Time, we used the meeting length recommendations from the Scrum Guide for a one month sprint to calculate the meeting burden rate. The number was 22.5%, assuming everyone is involved in each meeting and the meetings toe the line in terms of the guidance provided. One of the common recommendations to mute the meeting overhead problem is to use shorter sprints or iterations. 

One of the common pieces of advice is that many of the meetings scale (or de-scale linearly). If 4 weeks is 4 hours, 1 week would be 1 hour. While this common advice is reasonable, it is not part of the Scrum Guide. I pinged a few practitioners that I had not trained and heard the same advice, so we will use this assumption, along with the guidance on involvement from the Guide. Using the same table as before for a 2-week sprint 

MeetingDriverScrum Guide Guidance for  2-week SprintSprint PlanningSizeMaximum of 4 hoursDaily ScrumPeople15-minute time-boxed event dailySprint ReviewLength – Size2-hour meetingRetrospectiveLength1.5-hour meeting for one-month SprintsRefinementLength – SizeNo more than 10% of the team capacity

Assuming linearity and the same 7 person team working 40 productive hours a week equates to 560 hours for a 2-week sprint. The worst-case total meeting time for this length would be 126 hours (4 hrs planning, 2.5 hrs Daily Scrums, 2 hrs Sprint Review, 1.5 hrs Retrospective, and 8 hrs of Refinement — all multiplied by 7). The burden rate is 22.5%. Ouch. But that ouch is no different than the percentage time stuck in meeting for a one-month sprint! [This mental experiment suggests shorter sprints would be just as meeting bound as longer sprints with over ⅕th of the team’s time stuck in meetings. A straight read of the Scrum Guide does not indicate that there will be less meeting overhead, arguably since the Guide is mute on whether the ceremonies scale linearly the level of overhead could go up.  Fortunately, this is not what happens in the real world or at least shouldn’t (I have noted before that there are a lot of bad implementations of Scrum, agile, and other development approaches).  

Let’s pick on the longest tent pole, refinement, to challenge the assumptions. There are several problems with using a blanket 10% and involving the whole team. The first issue is that 10% is a maximum; in my experience, the amount of effort is closer to 5 – 7% and falls as the team gains a higher understanding of the backlog. Secondly, many teams use an approach that only involves part of the team for refinement (one approach is Three Diverse Humans – formerly known as the Three Amigos).  In both cases, the amount of meeting time is reduced, but there is no indication that the percentage of time in meeting changes based on

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:

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
