CUDA[IsEnabled] - check if CUDA(R) acceleration is turned on

Calling Sequence

IsEnabled( )

Description

• 

The IsEnabled function returns a value of true if Compute Unified Device Architecture (CUDA) acceleration is turned on and false otherwise.

• 

Use the Enable function to turn CUDA acceleration on and off.

• 

If your computer does not support CUDA, an error will be displayed. For more information about supported hardware, see Supported Hardware for CUDA Acceleration.
