Discussion: Validation with nitro on different CPU instruction sets

[hiro-v]

Problem Link: Check out the issue on GitHub: Issue #2432.

Why This Matters: Jan is designed to work best with newer technology, using something called AVX2 for processing. However, if you're using an older computer, you might not have AVX2, but something like AVX or AVX512 instead. We want to make sure Jan works well for everyone, regardless of their computer's age.

What We've Found: Jan might not work perfectly on every type of computer yet. We're still figuring this out and could use your help to ensure it works for everyone. A new version of Nitro (0.3.15) is out, offering different versions to match your computer's capabilities. Check it out here.

Our Plan:

• March 25 - April 4: We're guiding users through fixing issues by manually updating their Nitro version.
• Future Date: We'll update Jan so it automatically supports all types of computers without needing these manual steps.

How to Manually Fix It:

1. Locate Your Jan Folder: You should find it at C:\Users<name>\jan on Windows or ~/jan on Linux.
2. Check Your CPU: Look up your CPU (like Intel(R) Core(TM) i7-3770 CPU) online to find its capabilities (e.g., AVX, AVX2, AVX512). Intel's official pages are a good source. 3.Do You Have a Graphics Accelerator? If you have an NVIDIA, AMD, or Intel Arc GPU, it's important to choose the right Nitro version.
3. Download the Right Nitro Version: Depending on your system and any accelerators, pick the correct version from the Nitro 0.3.15 release.
4. Unzip the Files: Use the guides provided for Windows or Linux to unpack the files.
5. Replace the Old Nitro: Move the new Nitro files to the right location in your Jan folder. Make sure it's not nested in another folder.
6. Restart Jan: Close and reopen Jan, then check if it's working better.

Let Us Know How It Went: After trying these steps, please share your experience in the GitHub issue comments with details like your Jan version, OS, CPU, and whether you have an accelerator. This helps us make Jan even better for everyone!
