@jlperla code combined from various users here on Discourse  
Julia [Original](https://github.com/vduarte/benchmarkingML/blob/master/LSMC/Julia.jl)  
Julia [Simple](https://github.com/azev77/LSMC-Option-Pricing-in-Julia/blob/master/AZ_vec.jl)  
Julia [Fastest](https://github.com/azev77/LSMC-Option-Pricing-in-Julia/blob/master/alvrg.jl)

“Simple” is much easier to understand than the original code & for every order size is faster than Matlab/Numpy/R.  
“Fastest” is even faster, but I don’t find it easy to follow.  
PS: I’m sure “Fastest” can be optimized a lot more  
PPS: I got PyTorch to work on my mac (not TF yet)  
“Fastest” is faster than PyTorch which is faster than “Simple”

Speed on my machine.
