# meshThreadgroupSizeIsMultipleOfThreadExecutionWidth

Provides a guarantee to Metal regarding the number of threadgroup threads for the mesh stage of a pipeline you create from this descriptor.

## Declaration

```swift
var meshThreadgroupSizeIsMultipleOfThreadExecutionWidth: Bool { get set }
```

## Discussion

Discussion If you set this property to true, you state to Metal that when you use a mesh render pipeline you create from this descriptor, the number of threadgroup threads you dispatch for the mesh stage is a multiple of its meshThreadExecutionWidth. The compiler’s optimizer can use this guarantee to generate more efficient code. This property’s default value is false.
