I was wondering if Julia has something similar to the arrayfun in MATLAB that makes GPU accelerated MC simulation super easy. [Using GPU ARRAYFUN for Monte-Carlo Simulations - MATLAB & Simulink Example](https://www.mathworks.com/help/distcomp/examples/using-gpu-arrayfun-for-monte-carlo-simulations.html)

[GPUArrays.jl](https://github.com/JuliaGPU/GPUArrays.jl) supports `map` and `mapreduce`.

The document is missing. What is the relation between GPUArrays and CuArrays?

It lets you write code that works for multiple backends. CuArrays is one possible backend.
