Detailed Description

Contains all QI memory space that is allocated per stream.

Definition at line 24 of file QI.h.

Constructor & Destructor Documentation

§ ~StreamInstance()

QI::StreamInstance::~StreamInstance ( )

inline

Delete the stream instance.

Bug:: Why aren't the device_vec instances deleted?

Definition at line 46 of file QI.h.

                           {
             cufftDestroy(fftPlan);
         }

Member Function Documentation

§ memsize()

int QI::StreamInstance::memsize ( )

inline

Return the total size of memory in bytes used for QI by each stream.

Returns: Memory size in bytes.

Definition at line 54 of file QI.h.

                       {
             size_t fftSize;
             cufftGetSize(fftPlan,&fftSize);
             return d_QIprofiles.memsize() + d_QIprofiles_reverse.memsize() + d_quadrants.memsize() + fftSize;
         }

Member Data Documentation

§ d_DebugOutput

device_vec<float> QI::StreamInstance::d_DebugOutput

Extra device vector specifically for arbitrary debug output GPU_DEBUG is defined at the top of gpu_utils.h.

USAGE: Fill with any kind of data in a function Output in any host code to a csv file using DbgOutputVectorToFile.

Definition at line 38 of file QI.h.

§ d_QIprofiles

device_vec<float2> QI::StreamInstance::d_QIprofiles

Memory to hold the concatenated X and Y profiles generated from the quadrant profiles. In-place forward and backward FFT is performed in this memory. Size is batchSize * (2 axes) * (2 * QIParams::radialSteps).

Definition at line 26 of file QI.h.

§ d_QIprofiles_reverse

device_vec<float2> QI::StreamInstance::d_QIprofiles_reverse

Memory to hold the reversed X and Y profiles. In-place forward FFT is performed in this memory. Size is batchSize * (2 axes) * (2 * QIParams::radialSteps).

Definition at line 27 of file QI.h.

§ d_quadrants

device_vec<float> QI::StreamInstance::d_quadrants

Memory to hold the quadrant profiles. Size is batchSize * (4 quadrants) * QIParams::radialSteps.

Definition at line 28 of file QI.h.

§ d_shiftbuffer

device_vec<float> QI::StreamInstance::d_shiftbuffer

Calculation buffer. Size is batchSize * qi_FFT_length.

Definition at line 25 of file QI.h.

§ fftPlan

cufftHandle QI::StreamInstance::fftPlan

Handle to make calls to CUFFT. A single CUFFT plan can be used for both forward and inverse transforms.

Definition at line 40 of file QI.h.
