Number Cruncher
100 points Hard

I have a program that crunches some data. It's taking forever to compute the value, could you help me crunch this data file? Thanks!

Program link: https://mega.nz/#!eW4DWarQ!7evWrgj93gIfpmY5ksXbzmER_rKM0taw9hZ4v9mq0DE

Data file attached below (fixed).

Analysed a lot, but it deserves. To know what happens in the function with jmp rdi is the key, after that you can write a program with a more effective algorithm (can be found on the web easily if you really know what happens), the result will appear soon.

I thought that while it was fun to RE the function you describe, I wasn't a huge fan of just searching for a faster algorithm to copy-paste.
