hadamardproductsimd's Introduction

Hadamard Product with SIMD

This is a testbed for trying out the acceleration of taking the Hadamard Product of two data sets using SIMD. The current algorithm is the scalar version. As I learn assembly, SSE, and AVX I will try new approaches. Pull Requests welcome if you have alternative approaches to suggest ๐Ÿ˜Š.

The StackOverflow question for approaches is here.

Current performance results:

Method Mean Error StdDev
Scalar 78.89 us 1.342 us 1.436 us
SSE 32.50 us 0.391 us 0.347 us
AVX 25.22 us 0.109 us 0.096 us
