    Major Release v2.1.0

    Changes

    • Huge refactor, a lot of code has been pulled from an older version to fix regressions in v2.0.0
    • GPUs work again!
    • Older documentation should generally still apply, but for the time being, a lot has changed
    • astra-gpu is no longer a separate module, this is because in the future it will be re-written in another language with better C compatibility (Likely C# or C++)

    Future Plans

    • Rewrite big chunks of the project in C.
      • I want to migrate the project from relying on Rust; in an ideal world you can simply use the C library for extra language support
      • A lot of the C code has been removed in this update in order to fix GPU compute and at least removes some of the overhead from Rust -> C.
    • 16 bit multithreading, and further optimizations are planned long term

    Major release v2.0.0.

    This update is a pretty big one with some regressions and lots of improvements.

    What's new:

    • New documentation, making the library much easier to use
      • Compilation guide for Android, Linux and Windows
      • Explanation of the C code and the relation Rust has with it
      • Quick-start guide with code examples to get going quickly
    • Huge refactor
      • It's now a Rust workspace!
      • The old C code is now in astra-common - Utilities that could be called from anywhere
      • There are now three libraries provided by astra-api, libastra32, libastra32avx2 and libastra32avx512 using no avx, avx2 and avx512 specifically
    • The compute code is now written in C, rather than Rust.
    • No longer using Rust's CC crate, instead using CMake to compile the C libraries, further separating the Rust and C codebases
    • We now have an actual build workflow!

    Regressions:

    • Slight performance decrease in some scenarios. I have a fix that will be coming in v2.0.1
    • No more 16-bit support. This will come back at some point, I just wasn't happy with the implementation of it prior

    Future Plans:

    • Astra-GPU isn't very compatible with non-rust languages, this should get changed
    • Re-implement 16-bit floats.
      • GPU support this time
      • No AVX2 support at all rather than messing with conversions to 32 bit
      • AVX512-first
    • Multithreading! This has huge promise for certain network layouts in terms of improving performance.
      • This has been experimented with before, but not to much luck.
    • Improved performance in more scenarios (I am preparing a performance uplift for v2.0.1)

    v1.2.2 Stable

    juniper released this 2025-07-10 17:28:13 +01:00 | 146 commits to main since this release

    A minor update purely to refactor some chunks of the code - One of several to come.

    • The project is now a Rust Workspace
    • C code has been split into astra-common
    • A new "project" astra-gpu has been made to include the GPU acceleration, rather than being baked into the rest of the API

    • Cargo.toml now has more defined fields in it (license, readme, docs, homepage, repo, keywords, description)
    • Documentation added under the docs directory in this repository
    • Made the serialization features for neural networks their own feature rather than always building the dependencies
    • Now using stable rust instead of nightly

    juniper released this 2025-03-29 15:19:34 +00:00 | 281 commits to main since this release

    The first full release of the API.

    It's still somewhat work in progress, but it is stable enough to be considered a release.

    Please make sure you report any bugs with this version, though, some features may still be missing for a while.
