Fast variance in Go

This project implements population variance in go. The project demonstrates performance speed ups with native c-code built for different systems.

Prerequisites

• clang or gcc
• go 1.13.1
• make

Usage

go test . -test.v

This software can be run without c-code and c-compiler. Just do

CGO_ENABLED=0 go test . -test.v

Benchmarks

The raw performance results from 2019 are available as an excel spreadsheet as performance results.xlsx.

Appendix

The performance benchmarks were presented at Oslo Go User Group Go Oslo December Meetup @Vipps 🎅🏻 🧡 at Wed, Dec 4 · 6:00 PM 2019. The powerpoint presentation is available at Interfacing with native code.
