SIMD Examples

This repo contains SIMD implementations of

1. Absolute value calculator

2. Minimum and Maximum value calculator

NOTE:

We are able to run SSE instrinsics on ARM using a header file sse2neon.h, which converts the SSE intrinsics into equivalent ARM NEON intrinsics. Running AVX instrinsincs on ARM machine is not possible.

We are also using OpenMP to run multi-threaded implementation of the benchmarks.

How to compile

Run make all which will compile both min-max.cpp and abs.cpp and store the executable in build/src directory. Have a look at the Makefile to see which options are included.

How to benchmark

Simply run scripts/bench.sh ( or scripts/benchM1Arm.sh if running on Apple M1 / any ARM machine) with

1. hostname: output files will be stored in stat/hostname directory

2. benchmark to run: currently min-max or abs

For example:

./scripts/bench.sh my-machine min-max

Output of the script is a csv file containing the time taken for different scenarios, and a PNG image of the plot. The output will be stored in stat/hostname directory.
