# MetalComputeAttributeChecker

 

 

## What it does?

It shows the values of **Kernel Function Input Attributes** as the input parameters to the Metal Compute kernel.

The values are taken in the kernel at the specified thread in the specified configuration.

The thread is specified by the `thread_position_in_grid` attribute.

The configuration is specified by `groups_per_grid` and `threads_per_threadgroup` to 

`dispatchThreadgroups()` of `MTLComputeCommandEncoder`.

It supports both Macos as a command-line tool, and iOS as a UI App.

See https://developer.apple.com/metal/Metal-Shading-Language-Specification.pdf for details.

## How it is useful?

Those attributes of METAL are not so well documented as CUDA counterparts, and I think the best way to learn is to run it on actual devices and see the bevavior.

## Install

### Macos

Open a terminal, go to `MetalComputeAttributeChecker/MetalComputeAttribs/` and `make all`.

The code is written in C++/Obj-C.

### iOS

Open `MetalComputeAttributeChecker/MetalComputeAttribs.xcodeproj` in Xcode.

The code is writtin in SwiftUI.
