Time to BOTEC in C

This repository contains a few implementations of a simple botec (back-of-the-envelope) calculation in C:

• In the folder C-01-simple/, you can see a simple implementation, which passes large arrays around
• In the folder C-02-better-algorithm-one-thread/ you can see a better implementations, that passes around pointers to functions, which makes the implementation more efficient
• The top level samples.c uses the algorithm improvements in C-02..., and also implements multithreading using OpenMP

To do

• Add Windows/Powershell time-measuring commands
• Add CUDA?
• Update repository with correct timing
• Use better profiling approach to capture timing with 1M samples.
• See if program can be reworded so as to use multithreading effectively, e.g., so that you see speed gains proportional to the number of threads used
