# computeSubGroupSize

> Size of the compute thread group that supports efficient memory sharing on the GPU (Read Only).

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.6/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public static int computeSubGroupSize { get; }
```

### Remarks

The most efficient thread group size for a set of compute shader calls. This value takes synchronization and shared data into account. This value is a subset of the total workgroup size. It is also known as a "warp" or a "wavefront".
