 ** name **   <a name="deadlinecloud-Type-AcceleratorSelection-name"></a>
The name of the chip used by the GPU accelerator.  
The available GPU accelerators are:  
+  `t4` - NVIDIA T4 Tensor Core GPU (16 GiB memory)
+  `a10g` - NVIDIA A10G Tensor Core GPU (24 GiB memory)
+  `l4` - NVIDIA L4 Tensor Core GPU (24 GiB memory)
+  `l40s` - NVIDIA L40S Tensor Core GPU (48 GiB memory)
Type: String  
Valid Values: `t4 | a10g | l4 | l40s`   
Required: Yes

 ** runtime **   <a name="deadlinecloud-Type-AcceleratorSelection-runtime"></a>
Specifies the runtime driver to use for the GPU accelerator. You must use the same runtime for all GPUs in a fleet.   
You can choose from the following runtimes:  
+  `latest` - Use the latest runtime available for the chip. If you specify `latest` and a new version of the runtime is released, the new version of the runtime is used.
+  `grid:r570` - [NVIDIA vGPU software 18](https://docs.nvidia.com/vgpu/18.0/index.html) 
+  `grid:r535` - [NVIDIA vGPU software 16](https://docs.nvidia.com/vgpu/16.0/index.html) 
If you don't specify a runtime, AWS Deadline Cloud uses `latest` as the default. However, if you have multiple accelerators and specify `latest` for some and leave others blank, AWS Deadline Cloud raises an exception.  
Not all runtimes are compatible with all accelerator types:  
+  `t4` and `a10g`: Support all runtimes (`grid:r570`, `grid:r535`)
+  `l4` and `l40s`: Only support `grid:r570` and newer
All accelerators in a fleet must use the same runtime version. You cannot mix different runtime versions within a single fleet.
When you specify `latest`, it resolves to `grid:r570` for all currently supported accelerators.
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 100.  
Required: No
