Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

A fast, single queue thread pool created with C++20
Benchmarks is indeed a good question. Here is a C++17-style library for parallel function calls which avoids std::{function, future, promise} and uses disposable threads for running the functions. I have run a few benchmarks against a typical thread pool which uses a mutex and a condition variable and a vector of threads.

for_each with plain integers
You might consider using this header-only library.

Does Execution Policy in std::transform in gcc have any effect?
Using Lazy the simple header-only parallel library found here in Github.

Therads in Cpp
Unless you really want to play with "raw" C++ threads, you may be able to completely avoid them by using a library like this one. See the simple examples on the main page and check if they would suit your application.

How to force your code to use all CPU cores? In an efficient manner.
This header-only library might come in handy when experimenting with parallel functions. You can run any number of functions in parallel and gather the results conveniently. Take a look at the examples on the main page in Github and see if you find them useful.

Improvements of Clojure in his time
For parallel programming nowadays, personally I reach for C++ Taskflow when I really care about performance, or a mix of core.async and running multiple load balanced instances when I’m doing more traditional web backend stuff in Clojure.

How to go from intermediate to advance in C++?
Also, you can take a look to good libraries. The problem is that very often libraries are heavily templated, so It could be hard. For example, I like the style of the Taskflow library, I think is very clear, is relatively small, while makes use of more advanced techniques: https://github.com/taskflow/taskflow

gcl v1.1 released - Graph Concurrent Library for C++
Cool. Thanks! How does it compare to taskflow?

std::execution from the metal up - Paul Bendixen - Meeting C++ 2022
I've not seen yet, but it's been a bit since I looked last, any evidence of being able to build a computation graph and "save" it to re-run on new inputs. Something like https://github.com/taskflow/taskflow

Proper abstraction for this?
It seems you're describing something a generic parallel task framework. Check taskflow for a production ready example https://github.com/taskflow/taskflow/blob/master/

That one technology, question, or skill you never learned, and now you are haunted by during every new job conversation...

Parallel Computations in C++: Where Do I Begin?
If you want some sort of "job" system, where you submit items to a some sort of queue to be processed in parallel, try searching for a thread pool - there isn't one in the standard library, but there's about a million implementations online. There are more complicated versions of that idea, that describe computation as a directed acyclic graph, such as taskflow.

High level overview of my custom game engine
The tooling decisions affect engine design though. For example if you want to have visual representation of job graph as it happened in specific frame of interest you need to pass the information around about job relationships and output it to a tool of choice. For example see https://github.com/taskflow/taskflow

Is there any good reason not to build an open-source C++ project on Intels oneTBB?
I am aware of DAGs of task based threading library like Taskflow and HPX however the benefit they have is not obvious to me, as the following sequential section depends on the parallel part being completed fully. If you want to suggest elaboration on the benefits of this approach would be welcome.
