Detailed Description

An interface class for offloading data from GPU to CPU.

Member Function Documentation

loaded_on_gpu()

virtual bool gtsam_points::OffloadableGPU::loaded_on_gpu ( ) const

pure virtual

Check if the data is loaded on the GPU.

Implemented in gtsam_points::GaussianVoxelMapGPU, and gtsam_points::PointCloudGPU.

memory_usage_gpu()

virtual size_t gtsam_points::OffloadableGPU::memory_usage_gpu ( ) const

inlinevirtual

Memory usage in bytes on the GPU.

Reimplemented in gtsam_points::GaussianVoxelMapGPU, and gtsam_points::PointCloudGPU.

offload_gpu()

virtual bool gtsam_points::OffloadableGPU::offload_gpu ( CUstream_st *  stream = 0 )

pure virtual

Offload data from GPU to CPU.

Returns

true if the data offload is conducted, false if the data is already on the CPU

Implemented in gtsam_points::GaussianVoxelMapGPU, and gtsam_points::PointCloudGPU.

reload_gpu()

virtual bool gtsam_points::OffloadableGPU::reload_gpu ( CUstream_st *  stream = 0 )

pure virtual

Reload data from CPU to GPU.

Returns

true if the data upload is conducted, false if the data is already on the GPU

Implemented in gtsam_points::GaussianVoxelMapGPU, and gtsam_points::PointCloudGPU.

touch()

virtual bool gtsam_points::OffloadableGPU::touch ( CUstream_st *  stream = 0 )

virtual

Reload data from CPU to GPU (if necessary) and update the last access time.

Returns

true if the data offload is conducted, false if the data is already on the CPU
