// Evaluate a statically exported ggml computation graph with Metal

// - First, export a LLaMA graph:

//
// $ ./bin/metal llama.ggml

// The purpose of this tool is mostly for debugging and demonstration purposes.
// The main limitation of exporting computation graphs is that their sizes are static which often
