Yes, I've been outputting portions of the result which is a 
10_000 x 10_000 matrix but it's definitely a good idea to do a 
full reconciliation of the outputs from all the languages.

I'll probably do a blog on GitHub and it can be linked it on 
reddit.

Definitely, Julia has a very nice performance optimization 
section that makes things easy to start with 
https://docs.julialang.org/en/v1/manual/performance-tips/index.html, it helps alot to start getting your code speedy before you ask for help from the community.
