Module device 

Device management — cudaGetDeviceCount, cudaSetDevice, cudaGetDevice, cudaGetDeviceProperties, cudaDeviceSynchronize, cudaDeviceReset.

The CUDA Runtime maintains a per-thread current device. This module stores that state in a thread-local and exposes the standard Runtime API surface on top of the underlying driver API.

Structs

CudaDeviceProp

Subset of cudaDeviceProp exposed by the Runtime API.

Functions

device_reset

Explicitly destroys and cleans up all resources associated with the current device in the current process.

device_synchronize

Blocks until all preceding tasks in the current device’s context complete.

get_compute_capability

Returns the compute capability as a (major, minor) pair.

get_device

Returns the ordinal of the current CUDA device for the calling thread.

get_device_count

Returns the number of CUDA-capable devices.

get_device_properties

Returns properties of the specified device.

set_device

Selects device as the current CUDA device for the calling thread.
