Apple Juicer

A way to squeeze the compute and/or memory performance out of your Apple product.

Benchmarks

• GEMM: compute-bound workload evaluating the compute performance of the AMX subsystem
• STREAM: memory-bound workload evaluating the memory performance of the M-series memory subsystem

Prerequisites

Hardware

• Apple M-series processor

Software

I've intentionally kept the prerequisites minimal to potentially enable more folks to be able to easily run these benchmarks.

• Operating System: macOS Sequoia. Older versions may work, just not tested.
• AppleClang installed (default C++ compiler as part of Developer Tools on macOS)
  • Another compiler may work; however, prelimary C++23 support is required for std::print
• Homebrew with libomp package installed to the default location (/opt/homebrew)

Running

1. Clone the repository:

git clone https://www.github.com/willkill07/apple-juicer.git

2. Switch to the repository directory:

cd apple-juicer

3. Build the executable files:

make

4. Invoke your executable of choice (either ./gemm or ./stream)

./stream
./gemm
