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.

What are some C++ projects with high quality code that I can read through?
https://github.com/STEllAR-GROUP/hpx Modern C++ concepts incorporated in a threading library. Lots of useful techniques used in there and we are trying to keep our code base very tidy. Feel free to chime in our libera channel #ste||ar if you have any questions.

Any C++ open source projects for beginners?
https://github.com/STEllAR-GROUP/hpx Welcoming community + we have been part of GSoC for 4-5 years now so feel free to apply there when it opens ;)

Getting started with first HPC project
You definitely do not want to learn Boost, trust me. The cudatoolkit is fine, HPX is great, so are Dask, and Ray. I do not recommend MPI unless those computers you have use InfiniBand.

John "God" Carmack: C++ with a C flavor is still the best (also: Python performance "keeps hitting me in the face")
I personally like the ideas in Parallelism v2 TS, which is available in for libstdc++ 11 onwards. The reference implementation is a library named Vc (afaik Vc is the most popular SIMD library for C++), and this has also been implemented in recent versions of HPX.

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.

Would anyone be interested in an HPC coroutine library for MPI?
We're working on something similar, but based on sender/receiver in HPX (a lightweight threading runtime) and DLA-Future (distributed linear algebra currently based on (HPX) futures; based on sender/receiver in the future). With senders-as-awaitables this would also get you coroutine support for asynchronous MPI calls for free. We don't have that yet, but it's planned. In the meantime libunifex should be able to fill in the gaps.

Experiences with Concurrent Hash Map Libraries
junction has a very impressive performance benchmark here. Initially it worked for my application, but I ran into some issues: Only raw pointers are supported as either keys or values. This means I am responsible for memory management and it was a pain. junction's required dependency "turf" causes linker errors when compiling with -fsanitize=address because there are symbol name collisions. Every thread that accesses the hash map must periodically call an update function or memory will be leaked. No commits in over three years, GitHub issues aren't getting any attention. The author said it's experimental and he doesn't want it to become more popular
What are some alternatives?
When comparing HPX and junction you can also consider the following projects:
Taskflow - A General-purpose Parallel and Heterogeneous Task Programming System
moodycamel - A fast multi-producer, multi-consumer lock-free concurrent queue for C++11
Thrust - [ARCHIVED] The C++ parallel algorithms library. See https://github.com/NVIDIA/cccl
libcds - A C++ library of Concurrent Data Structures
RaftLib - The RaftLib C++ library, streaming/dataflow concurrency via C++ iostream-like operators
parallel-hashmap - A family of header-only, very fast and memory-friendly hashmap and btree containers.
