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
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.
