Function Documentation

AssertCUDADeviceAvailable() [1/2]

void open3d::core::cuda::AssertCUDADeviceAvailable

(

const Device &

device

)

Checks if the CUDA device-ID is available and throws error if not. The CUDA device-ID must be between 0 to device count - 1.

Parameters

device

The device to be checked.

AssertCUDADeviceAvailable() [2/2]

void open3d::core::cuda::AssertCUDADeviceAvailable

(

int

device_id

)

Checks if the CUDA device-ID is available and throws error if not. The CUDA device-ID must be between 0 to device count - 1.

Parameters

device_id

The cuda device id to be checked.

DeviceCount()

int open3d::core::cuda::DeviceCount

(

)

Returns the number of available CUDA devices. Returns 0 if Open3D is not compiled with CUDA support.

IsAvailable()

bool open3d::core::cuda::IsAvailable

(

)

Returns true if Open3D is compiled with CUDA support and at least one compatible CUDA device is detected.

ReleaseCache()

void open3d::core::cuda::ReleaseCache

(

)

Releases CUDA memory manager cache. This is typically used for debugging.

Synchronize() [1/2]

void open3d::core::cuda::Synchronize

(

)

Calls cudaDeviceSynchronize() for all CUDA devices. If Open3D is not compiled with CUDA this function has no effect.

Synchronize() [2/2]

void open3d::core::cuda::Synchronize

(

const Device &

device

)

Calls cudaDeviceSynchronize() for the specified device. If Open3D is not compiled with CUDA or if device is not a CUDA device, this function has no effect.

Parameters

device

The device to be synchronized.
