cpucheck's Introduction

CPUcheck

It is an easy CPU check tool.

There are N workers (where N is runtime.NumCPU).
A worker gets pseudo random bytes and calculates SHA-256 sum for it.
The cycle repeats for every worker during the time period.

Build

Use common go-way to build:

go build .

Examples of cross-compile builds:

# MS windows
GOOS=windows GOARCH=amd64 go build -o cpucheck_windows.exe .

# MacOS
GOOS=darwin GOARCH=amd64 go build -o cpucheck_macos .

Test

Github Actions is running for every master git-push.

go test -race -bench=. -benchmem -cover -v .

Parameters

Usage of ./cpucheck:
  -a string
        algorithm (sha256, md5, gzip, all) (default "sha256")
  -s int
        data size (bytes) (default 65536)
  -t int
        time duration (seconds) (default 10)
