A CUDA device
data DeviceProperties Source #
The properties of a compute device
Constructors
| DeviceProperties | |
Fields

Instances
data DeviceAttribute Source #
Device attributes
Constructors
Instances
| Enum DeviceAttribute Source # | Return the compute compatibility revision supported by the device |
| Eq DeviceAttribute Source # | |
| Show DeviceAttribute Source # | |
GPU compute capability, major and minor revision number respectively.
data ComputeMode Source #
The compute mode the device is currently in
Constructors
| Default | |
| Prohibited | |
| ExclusiveProcess |
Instances
Possible option flags for CUDA initialisation. Dummy instance until the API exports actual option values.
initialise :: [InitFlag] -> IO () Source #
Initialise the CUDA driver API. This must be called before any other driver function.
attribute :: Device -> DeviceAttribute -> IO Int Source #
Return the selected attribute for the given device.
Return the number of device with compute capability > 1.0.
