TargetDevice
is an option for certain functions that specifies whether CPU or GPU computation should be attempted.
Details


- Typically possible settings are "CPU" and "GPU".
- TargetDevice can be used with NetTrain to determine on which device a network is trained.
- TargetDevice can be supplied when applying a trained neural net to an input to determine on which device the network is evaluated.
- With the setting TargetDevice->"GPU", the Wolfram Language will attempt to use a GPU if it is available on your computer.
- TargetDevice{"GPU",n} allows a specific GPU to be used, where n is an integer between 1 and the number of GPUs available on your computer.
- TargetDevice->{"GPU",All} specifies that all available GPUs should be used jointly.
- TargetDevice->{"GPU",{n1,n2,…}} specifies that a specific subset of the GPUs should be used jointly.
- Only NVIDIA GPUs with the following compute capabilities are currently supported:
-
Capability 3.7 Kepler architecture Tesla K80 Capability 5.0 Maxwell architecture GTX 750 etc. Capability 5.2 Maxwell architecture GTX 980 etc. Capability 6.0 Pascal architecture Tesla P100 etc. Capability 6.1 Pascal architecture GTX 1080 etc. Capability 7.0 Volta architecture Tesla V100 etc. Capability 7.5 Turing architecture RTX 2080 etc. Capability 8.0 Ampere architecture Tesla A100 etc. Capability 8.6 Ampere architecture RTX 3080 etc. - In a fresh Wolfram Language installation, TargetDevice->"GPU" and related GPU settings will automatically download additional libraries ("MXNetResources"). Such a download can also trigger again in case updates are available. The download can also be started manually by running PacletInstall["MXNetResources"].
