  • Signal processing library
    7 projects | | 6 Nov 2021
    I used basic_dsp a while back and found it lacking. I was hoping to find something that uses the ndarray datatype but i'm not seeing this yet. If you're primarily trying to learn though it might not really matter which library you contribute to. As for myself, I just picked the one that was most used and actively worked on at the time. However I keep an eye out on other libraries; if I see something take off, I might switch over. Either way you'll learn and can point to it as work accomplished.
  • Searching help for Rust Image Manipulation
    2 projects | | 31 Jul 2021
    Most libraries use either an older C/C++ dynamically or statically. I was looking into maybe rewriting some image manipulation functions in Rust using ndarray (which would then allow for both hardware, gpu and multithreading acceleration), but it would take a very long to get fully into the subject.

    The best way would to use a crate for this, such as ndarray, which provides some good ways to do this.
  • Making Maintaining Easier
    5 projects | | 25 Apr 2021
    First, let me explain a crate, where old dependencies do matter. There is one very handy crate called nshare. It's used for converting images into ndarrays. The libraries between nshare converts are regularly updated, for example to support new formats or to make the usage more convenient. If one writes a new software there could be conflicts in versions of ndarray (for example), so we make sure, that nshare is always up-to-date and works with the newest versions in order to build the best code on it. Another example could be everything cryptographic. If there would be a security issue with ring we really want every dependent to be updated.

    well you can represent categorical values in `ndarray` for sure (even structured arrays [here](, but the memory has to be contiguous for BLAS/LAPACK and therefore it is impossible to mix continuous and categorical values. I was thinking that we could emulate categorical values with a descriptor field for the type of each feature and then just use floats to represent them.

  • Does Rust still depend on LLVM?
    3 projects | | 18 May 2022
    Kinda - SPIR-V is an intermediate representation that can be consumed by graphics drivers and compiled down by them to the GPU's native code. In that sense it's more similar to emitting LLVM IR than e.g. x86 machine code. Similarly, Rust-CUDA emits NVVM IR, which is a subset of LLVM IR.

    I'm looking for some good sources I can read to see arguments for and against. I'm relatively new to Rust myself, but I am looking at the Rust-CUDA project (and have contacted the developer). I am primarily interested in Rust for this task because of what it offers in terms of memory safety, though I realize that some of the tools/algorithms rely heavily on shared memory between threads. Really, any good reads that you folks could offer would be greatly appreciated.
  • [Media] Follow-up to my previous path tracing in rust post, after a lot of work and trial and error, Rust can now do Hardware Raytracing on the GPU using OptiX, sharing the exact same core rust code with the CPU and GPU renderers.
    1 project | | 31 Jan 2022
    After nearly a year of work in total, i am happy to announce i was able to bring hardware raytracing to Rust CUDA using the OptiX SDK. OptiX is an SDK based on CUDA which provides fast raytracing pipelines which are hardware-accelerated on Turing and Ampere GPUs. OptiX is half a CPU-side C API, and half a GPU-side C++ library i had to recreate in rust using inline assembly.

    I finally got rust-cuda to generate optix-compatible code, this is the first picture rendered using hardware raytracing 100% in rust. Rust GPU code and Rust CPU code. I will be making a follow-up to my path tracer in rust post once i make it use OptiX. You can find the (very early) code for this picture here.
