The file appears because you are using an application built with the MACE framework. It is most commonly found on:
When an app initializes an AI framework like MACE, the framework uses OpenCL to talk to the GPU. Normally, OpenCL compiles the necessary neural network kernels (code blocks) from scratch at runtime —meaning every single time you open the app or trigger the feature. This runtime compilation causes a few distinct problems:
To understand mace-cl-compiled-program.bin , it helps to understand how the underlying framework utilizes heterogeneous mobile hardware. What is MACE?
Developers often encounter issues where MACE cannot locate or write to this file, leading to warnings or errors. 1. "File does not exist" Warning

This file does not contain your photos, contacts, or messages. It contains GPU assembly code. It cannot be "opened" to reveal personal data.
A critical, often invisible component of this acceleration process is the generated OpenCL binary file, commonly named mace_cl_compiled_program.bin . This file acts as a cache, storing compiled OpenCL kernels to accelerate the initialization and inference of neural networks on mobile GPUs. What is mace_cl_compiled_program.bin ?
