Tools that honor the GPU ID environment identify the GPU to use to process your data.
Usage notes
- Identify the compute GPU to use if more than one is available.
- Use the NVIDIA System Management Interface (nvidia-smi) command tool, which is included with CUDA, to check the order and status of GPUs. The nvidia-smi command tool also supplies information such as GPU load, memory load, temperature, and other GPU performance characteristics.
- It is recommended that you use one GPU for display only—with the monitors connected to it—and set the other GPU for computing only. This will ensure that the compute and display GPUs will not interfere with each other and will maximize efficiency.
Dialog syntax
Set the GPU identification number to use to process the data.
- GPU ID—The GPU identification number to use to process the data. The default will be blank, which means any or all of the available GPUs can be used.
Scripting syntax
arcpy.env.gpuId = GPU_ID
| Parameter | Explanation |
|---|---|
gpuId | The GPU identification number to use to process the data. This is an integer value. The default is None, which means any or all of the available GPUs can be used. |
Script example
import arcpy
# Set the gpuId environment to 1
arcpy.env.gpuId = 1
