  • Performance of High-level Languages

    by Vanessa McHale | Compilers

    It is quite possible to beat established (array) implementations with special cases and bittwiddling.

  • Softmax in Apple As an Example of Explicit Rank

    Consider a softmax layer from Aditya Srinivas Menon's tutorial:

  • Optimizing Array Code With Inferred Type Information

    by Vanessa McHale | Vector Languages

    Apple, being a JIT compiler with shape types, is able to do a number of optimizations based on inferred dimension (and rank). Rank is almost always known in practice, so such optimizations are pertinent.

  • Streaming Compression/decompression in Haskell via Laziness

    by Vanessa McHale | Haskell

    In Haskell, one can present a streaming compression/decompression API with lazy bytestrings.

  • Lessons from Writing an Array Compiler II

    by Vanessa McHale | Compilers

    I just finished adding another mid-end to my Apple JIT compiler, motivated to get rank facilities right. However, there remain significant shortfalls.
