Futhark-J Bridge is a library that allows writing Futhark code inline within J programs for automatic parallel CPU execution. It handles compilation, caching, and FFI calls automatically, with benchmarks showing significant speedups (up to 1525x) for compute-intensive workloads like Mandelbrot generation, though simple memory-bound operations are better handled natively by J.
Background
Futhark is a purely functional data-parallel programming language known for generating highly efficient GPU and CPU parallel code. J is an array-oriented programming language with strong numerical computing capabilities but limited built-in parallelism across multiple CPU cores.
