    Details

    • Type: Improvement
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: 0.15.1
    • Fix Version/s: 0.16.0
    • Component/s: Rust

      Description

      In a comment to an open ticket for optimising a cast kernel by using SIMD, Andy Thomason mentioned that LLVM does autovec well for Rust.

      I'd like to explore whether we could improve the kernel performance by simplifying the loops enough to allow the compiler to vectorise.
