Constructor & Destructor Documentation

risa::cuda::DetectorInterpolation::DetectorInterpolation ( const std::string & configFile )

Initializes everything, that needs to be done only once.

Runs as many processor-thread as CUDA devices are available in the system. Allocates memory using the MemoryPool for all CUDA devices.

Parameters

[in] configFile path to configuration file

Definition at line 46 of file DetectorInterpolation.cu.

risa::cuda::DetectorInterpolation::~DetectorInterpolation ( )

Destroys everything that is not destroyed automatically.

Tells MemoryPool to free the allocated memory. Destroys the cudaStreams.

Definition at line 72 of file DetectorInterpolation.cu.

Member Function Documentation

auto risa::cuda::DetectorInterpolation::process ( input_type && sinogram ) -> void

Pushes the sinogram to the processor-threads.

Parameters

[in] sinogram input data that arrived from previous stage

Definition at line 78 of file DetectorInterpolation.cu.

auto risa::cuda::DetectorInterpolation::processor ( int deviceID ) -> void

private

main data processing routine executed in its own thread for each CUDA device, that performs the data processing of this stage

This method takes one sinogram from the input queue sinograms_. So far, the detector interpolation is performed on the host. Thus, the data is transfered from host to device, the raw data sinogram is interpolated and afterwards, transfered from device to host.

Parameters

[in] deviceID specifies on which CUDA device to execute the device functions

Definition at line 105 of file DetectorInterpolation.cu.

auto risa::cuda::DetectorInterpolation::readConfig ( const std::string & configFile ) -> bool

private

Read configuration values from configuration file.

All values needed for setting up the class are read from the config file in this function.

Parameters

[in] configFile path to config file

Return values

true	configuration options were read successfully
false	configuration options could not be read successfully

Definition at line 142 of file DetectorInterpolation.cu.

auto risa::cuda::DetectorInterpolation::wait ( ) -> output_type

Takes one sinogram from the output queue results_ and transfers it to the neighbored stage.

Returns: the oldest sinogram in the output queue results_
