Optimisation_Examples

Major Speed Up

• Compiler Optimisation (Magic);
• Pass by reference;
• Parralelism (OpenMP MPI GP-GPU);
• Algorithmic optimisation.

Other Considerations

• Use cach-friendly data structures (contiguous in memory);
• Use stack varibles where possible (allocation and deallocation is faster on stack);
• Reduce number of function calls (inline small functions);

Compilation

g++ ./src/main.cpp ./src/functions.cpp -o main -I ./src/ -O3 -std=c++20 -fopenmp
