Challenge Problems
Push your limits with advanced challenges
Create a C++ function that performs an addition on an array of integers, first written in scalar form and then optimized using manual vectorization. Discuss the performance implications.
💡 Hint: Look up SIMD intrinsics for specific platforms to implement the manual vectorization.
Analyze a provided loop’s code for loop dependencies that prevent vectorization. Suggest modifications for optimization.
💡 Hint: Consider loop unrolling or redesigning data flow.
