/// @brief Tag for a device adapter that uses a CUDA capable GPU device.
|
|
///
|
|
/// For this device to work, VTK-m must be configured to use CUDA and the code must
|
|
/// be compiled by the CUDA `nvcc` compiler. This tag is defined in
|
|
/// `vtkm/cont/cuda/DeviceAdapterCuda.h`.
|
|
|
|
// We always create the cuda tag when included, but we only mark it as a valid tag when
|
|
// VTKM_ENABLE_CUDA is true. This is for easier development of multi-backend systems.
|
|
//
|
|
// We usually mark the Cuda device as valid if VTKM_ENABLE_CUDA even if not compiling with Cuda.
|
|
// This is because you can still call a method in a different translation unit that is compiled
|
|
// with Cuda. However, if VTKM_NO_ERROR_ON_MIXED_CUDA_CXX_TAG is set and we are not compiling with
|
|
// Cuda, then the device is marked invalid. This is so you can specifically compile CPU stuff even
|
|
// if other units are using Cuda.
