Generate CPU load on Windows/Linux/Mac.

Install

go get -u github.com/vikyd/go-cpu-load

or download binary file directly

Usage

example 01: run 30% of all CPU cores for 10 seconds

go-cpu-load -p 30 -t 10

example 02: run 30% of all CPU cores forver

go-cpu-load -p 30

example 03: run 30% of 2 of CPU cores for 10 seconds

go-cpu-load -p 30 -c 2 -t 10

• all CPU load = (num of para c _ num of p) / (all cores count of CPU _ 100)
• may not specify cores run the load only, it just promise the all CPU load, and not promise each cores run the same load

Parameters

--coresCount value, -c value   how many cores (optional, default: 8)

--timeSeconds value, -t value  how long (optional, default: 2147483647)

--percentage value, -p value   percentage of each specify cores (required)

--help, -h                     show help

Build

go build

test

go test -v

currently only provide Windows testing

How it runs

• Giving a range of time(e.g. 100ms)
• Want to run 30% of all CPU cores
  • 30ms: run (CPU 100%)
  • 70ms: sleep(CPU 0%)
