chipStar 1.0 released! It's a tool for compiling and running CUDA/HIP applications on SPIR-V-supported OpenCL or LevelZero platforms. v1.0 can already run various HPC applications correctly. See: https://github.com/CHIP-SPV/chipStar/releases/tag/v1.0
#opencl #levelzero #spirv #cuda #hip

At the very least, this could give us support for #Intel hardware, and, at least in theory, potentially any device with #OpenCL2 and #SPIRV support —such as the Mali GPU on my phone! I would be very curious to test the performance on it compared to the CPU of the same device.

yet another "why #Vulkan is so challenging" blog post, this time from a #compiler author's point of view, specifically concerning the difficulties that arise from working with a control flow graph rather than an AST

Yes, that's right.
DXC was Stadia's production HLSL compiler, running on Linux, targeting Vulkan SPIR-V.

Nice demo! Yay for flexibility in shader langauges #spirv

@romainguy with support for #spirv shaders :)

Check out the camera-ready version of our #popl2023 paper on using formal technique to improve the #SPIRV programming language. Joint with Vasileios Klimis, Jack Clark, @wicko3, Alan Baker and @dneto.

The POPL 2023 conference program has been posted. https://popl23.sigplan.org/program/program-POPL-2023/?track=POPL%20

There's a SPIR-V paper, about how we used formal methods to fix bugs and ambiguities in the definition of structured control flow. (Fixes landed in SPIR-V 1.6 Rev 2).

It provides a solid foundation for control flow reconstruction algorithms, e.g. Google's Tint translator from SPIR-V to WGSL.

Here is an older video of the #spirv graph tool. Whenever I see it I want to pickup that project again but I have kinda moved on from C++ I'm hobby projects :gamedev: . #vulkan #gamedev

I realized I haven't posted much of my side projects except for the #gameboy stuff. So today I want to highlight this prototype: https://github.com/rAzoR8/Proto

A #spirv #shader assembly node graph tool that shows the generated code as you go.

Note that, in the case of #TornadoVM, it is fully transparent. The Java code is a subset of Java that expresses either sequential or parallel applications, and the compiler generates #SPIRV binaries, and uses the low-level stack of #oneAPI to run on Intel Graphics, including discrete ARC GPUs!

It's "spear vee"

Mike Houston proposed the original SPIR at the January 2011 Khronos F2F. He gave it the name, expanded the acronym *and* was explicit about the pronunciation as "spear".

SPIR-V came later. Khronos has always pronounced it "spear vee"

That said, language is a living thing, so use what you like.

Windows Subsystem for Linux in the Microsoft Store is now generally available on Windows.

I have been using it for a while and it is great. I can even run applications on discrete and integrated GPUs with #OpenCL, and #SPIRV. Good to see Microsoft is pushing for this.

My C++ to SPIR-V framework is now open-source on GitHub: https://github.com/rAzoR8/SPEAR
#cpp #vulkan #spirv

DirectXShaderCompiler now runs on Linux.

Cross-compiling from HLSL to Vulkan's SPIR-V shader format.

This is a tool for converting one subtype of DirectX code to Vulkan. Formerly the tool only ran on M$ Spydows.

Easier porting to Linux to use Linux as actual development platform when migrating to Vulkan.

Another small step of the now many steps in making Vulkan support practical for more different use-cases!
