AMD Releases Brotli-G For GPU-Accelerated Brotli Compression

[ktecho]

I thought brotli was designed to be easy on hardware (being able to run on phones and such). What am I missing here? Why does it need to run on GPUs now?

Wow... English is not my primary language, so I skipped that part where they say that using a GPU is needed for brotli...

Could you point me to the specific text where they say that?

That converter is called Clang. Just fetch the DX compiler and compile it. Or wait until upstreaming of the HLSL front-end is finished (it's pending) and upstream Clang will do the trick, won't need MS's fork anymore.

Glslang/shaderc handles HLSL as well, and outputs SPIR-V.

Yes, weird to announce a new algo, hinting at improved performance, but not releasing any numbers.

I had to dig through the articles, but it linked to https://quixdb.github.io/squash-benc...#results-table.
This does not contain Brotli-G numbers, but is a very nice and comprehensive comparison of compression algos.

Better than nothing, I guess.

The problem is some algorithm don't scale well, then use GPU to just have 30% more performance is useless

I wonder if popping it into a HLSL to SPIRV converter works

To see how it scale, any benchmark to difference of performance?

just not AMD Radeon graphics products

Shouldn't it be "not just"? In my mind this has the completely opposite meaning. I got really confused reading this sentence.
