MacOSIOReport.jl

This Julia package provides functionality to monitor CPU and GPU usage on M-series macOS systems(i.e., Apple Silicon). It is inspired by and partially ports the vladkens/macmon project, originally written in Rust.

Prerequisites

• macOS with Apple Silicon (M-series) processor
• Julia (install using juliaup)

Installation

1. Clone the repository:

Usage

$ cat demo.jl
using MacOSIOReport: handle_raw

function main()
    msec = UInt64(1000)
    handle_raw(msec)
end

main()
$ julia --project demo.jl

This means:

• E-CPU (Efficiency cores) are running at 1418MHz with 7.9% usage
• P-CPU (Performance cores) are running at 1103MHz with 0.97% usage
• GPU is running at 333MHz with 0.97% usage
• CPU is consuming 0.29 watts of power
• GPU is consuming 0.015 watts of power
