# dispatchThreads(indirectBuffer:)

Encodes a compute dispatch command with an arbitrarily sized grid, using an indirect buffer for arguments.

## Declaration

```swift
func dispatchThreads(indirectBuffer: MTLGPUAddress)
```

## Parameters

- `indirectBuffer`: GPUAddress of a doc://com.apple.metal/documentation/Metal/MTLBuffer instance providing arguments. Lay out the data in this buffer as described in the doc://com.apple.metal/documentation/Metal/MTLDispatchThreadsIndirectArguments structure. This address requires 4-byte alignment.
