DeChat requires AVX512?

[andemening]

Hi

I tried running it on my homelab to test the execution but it would not work, because my old CPU only supports AVX or AVX2. The only log message I got was roughly "illegal instruction". I don't KNOW this is related to AVX SIMD instructions but I highly suspect this. It would make sense.

The work-lab server was able to run DeChat, and it has AVX 512.
What version of AVX is required? Are you able to, or planning on, porting the program to other versions of AVX?
Even though I have older CPUs on my homelab I still have modern GPUs installed. Therefore my question.

Thanks

我这边确认了：在 Core Ultra 9 275HX 上（WSL2 环境），lscpu 的 flags 里只有 avx / avx2，没有任何 avx512*。在这种不支持/不暴露 AVX-512 的情况下程序也能正常运行，所以它并不是必须 AVX-512 才能运行。
Confirmed on my side: on a Core Ultra 9 275HX (running under WSL2), lscpu shows avx / avx2 but no avx512* flags. The program runs fine there, so it does not require AVX-512 to run.
