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.

Anybody know why V-EZ has not been updated in 5 years?
I recently asked about something similar. AFAIK in terms of convenience layers, only vk-bootstrap is still maintained, other than vulkan.hpp bindings. There's also vookoo but it's rarely updated.
-
Are there any good c examples?
A shameless plug: here's a link to my repo https://github.com/jammymalina/vkbasicapp that could get you started. It's a WIP and far from done. The code is relatively structured, I got the inspiration from vk-bootstrap and I am Graphics And So Can You blogpost.

Writing Vulkan SPIR-V shaders in C++?
Great answer. Wanted to add on vk-bootstrap, does a lot of the initialization boiler plate for you: https://github.com/charles-lunarg/vk-bootstrap

What is the proper way to link libvulkan.1.dylib ith cmake while avoiding issues with the installed vulkan SDK?
It looks like the issue was on how I was using a library to load vulkan https://github.com/charles-lunarg/vk-bootstrap/issues/83
- I'm seeking for advice, after a month of learning Vulkan I feel like I'm going nowhere
-
Can I automate the first painful steps of vulkan?
vkguide is probably what you want, but in case you don't want to start your code with a guide, you can use vk-bootstrap to get started faster, it's what's used in vkguide.

Vulkan Framework Design Question
I just discovered vk-bootstrap today, and it looks like it'll make initialization code much much easier.
-
Is there any simple layer (C/C++) which would take care of the long syntactic sugar?
For what you are asking, vk-bootstrap is a library that mostly handles the very first 300-400 lines of vulkan code. https://github.com/charles-lunarg/vk-bootstrap

Adding HLSL and DirectX Support to Clang and LLVM
It may be close to a technical impossibility, but the Circle compiler by Sean Baxter is attempting it. That's based on an aggressive "de-pointerization" (see [1] in particular for details). There's also academic work[2] to compile C++ to shaders. I agree that it's an open question how well that will work out.
Also as pointed out elsethread, now that buffer device address is starting to land, the friction to compile pointer-intense C++ code should decrease even more. These are exciting times!

Writing Vulkan SPIR-V shaders in C++?
You can use circle c++ shader https://github.com/seanbaxter/shaders but it's limited to look linux afaik?

Where to Learn Vulkan for parallel computation (with references to porting from CUDA)
First we have Circle C++ shaders, which pretty much would tick all the boxes. Problem is it's closed source and only compiles host code on linux. Closed source isn't the biggest of issues actually, but prevents anyone from fixing the developers issue with interfacing with the windows ABI and getting the thing working on windows (which itself isn't something they are able to fix because windows doesn't provide the documentation to work with their ABI). However you could use it separately to compile your SPIR-V for windows since SPIR-V doesn't care about platform itself.

Has anyone seriously considered C++AMP? Thoughts / Experiences?
Yes, Vulkan GPU source is split, though technically in a way that makes it more similar to CUDA. Vulkan uses an intermediate format instead of consuming text code directly, meaning new features are easier to add and frontend code doesn't need to be passed to the vendors driver compiler. SPIR-V is like DXIL or PTX code for CUDA, basically LLVM IR for GPUs. The CUDA compiler compiles your device code into PTX code, and it's what enables you to have "non split" source code. There's even an option to have separate PTX code in CUDA. There are few projects that aim to bring Vulkan SPIR-V into source, including Rust GPU for rust (though it will still have to be in a separate file) and Circle C++ shader for C++.

Circle, the C++ Automation Language
My favorite use is putting user-defined attributes on data members, and using reflection to generate a UI to manipulate those values. I do it with these shadertoys:

Just mark your declarations up with custom attributes:

Unified Shader Programming in C++
I'm confused what is novel about this paper. We already have unified shader programming with circle C++, with way more features, and instead of having an SPIR-V compiler, they made a source to source compiler... We have quite a few of those.
I think shader specialisation is handled pretty well in circle. Since you can essentially run arbitrary C++ code at compile time, selection and specialisation of a shader can even depend on hardware specific benchmarks. There is an extensive repo with examples here: https://github.com/seanbaxter/shaders. One example decodes a sprite sheet stored as a png at compile time and creates a specialised compute shader for it. You can also easily implement a control UI based on reflection of uniform shader parameters.

Embark Studios has rewritten all their renderer's shader code from GLSL to Rust
There's a project doing something similar for C++ called Circle which is pretty incredible. In its core Circle is an extension of standard C++ which adds a ton of metaprogramming facilities and other productivity enhancing features, things the base language sorely lacks like full compile-time execution of regular C++ code which lets you do anything you can normally do from runtime during compile-time (including file I/O and networking), reflection, typed enums, pattern matching, hygienic macros, list comprehensions and language-native ranges, first class paramater packs and much more.

Code generation using attributes
I use them to automatically generate an ImGui interface for controlling a shadertoy here: https://github.com/seanbaxter/shaders/blob/master/README.md#user-attributes-and-dear-imgui
