CUDA mrisurf

Author: T.Witzel

Notes on CUDA implementation of some of the surface functions in mrisurf.c.

Implemented

TODO

• handle ripflag
• handle corner-cases
• consolidate cpu and cuda routines (the routines listed below are copies of the cpu versions, so much is redundant, making long-term maintenance a hassle)

mrisComputeMetricPropertiesCUDA

static int mrisComputeMetricPropertiesCUDA(MRI_CUDA_SURFACE *mrics,
                                           MRI_SURFACE *mris);

mrisIntegrateCUDA

static int mrisIntegrateCUDA(MRI_SURFACE *mris,
                             INTEGRATION_PARMS *parms,
                             int n_averages);

mrisLineMinimizeCUDA

static double mrisLineMinimizeCUDA(MRI_CUDA_SURFACE *mrisc,
                                   MRI_SURFACE *mris,
                                   INTEGRATION_PARMS *parms);

mrisComputeDistanceErrorCUDA

static float mrisComputeDistanceErrorCUDA(MRI_SURFACE *mris,
                                          MRI_CUDA_SURFACE *mrisc,
                                          INTEGRATION_PARMS *parms);

MRIScomputeSSE_CUDA

static double MRIScomputeSSE_CUDA(MRI_SURFACE *mris,
                                  MRI_CUDA_SURFACE *mrisc,
                                  INTEGRATION_PARMS *parms);
