boundaryConditions()

virtual void benchmarks::exahype2::ccz4::CCZ4::boundaryConditions ( const double *__restrict__  Qinside, double *__restrict__  Qoutside, const tarch::la::Vector< Dimensions, double > &  faceCentre, const tarch::la::Vector< Dimensions, double > &  volumeH, double  t, int  normal  )

overridevirtual

initialCondition()

void benchmarks::exahype2::ccz4::CCZ4::initialCondition ( double *__restrict__  Q, const tarch::la::Vector< Dimensions, double > &  volumeCentre, const tarch::la::Vector< Dimensions, double > &  volumeH, bool  gridIsConstructed  )

maxEigenvalue() [1/2]

virtual double benchmarks::exahype2::ccz4::CCZ4::maxEigenvalue ( const double *__restrict__  Q, const tarch::la::Vector< Dimensions, double > &  faceCentre, const tarch::la::Vector< Dimensions, double > &  volumeH, double  t, double  dt, int  normal  )

overridevirtual

Determine max eigenvalue over Jacobian in a given point with solution values (states) Q.

All parameters are in.

Returns

Max eigenvalue. Result has to be positive, so we are actually speaking about the maximum absolute eigenvalue.

maxEigenvalue() [2/2]

static GPUCallableMethod double benchmarks::exahype2::ccz4::CCZ4::maxEigenvalue ( const double *__restrict__  Q, const tarch::la::Vector< Dimensions, double > &  faceCentre, const tarch::la::Vector< Dimensions, double > &  volumeH, double  t, double  dt, int  normal, ::exahype2::Solver::Offloadable    )

static

To obtain the best performance, I recommend to man inline command to this signature and to copy the implementation into the header.

So it would read

static inline double maxEigenvalue( ... ) { code here }

The GPU offloading requires static functions. As we cannot overload the original (virtual) function with a static alternative, we do the TBB trick and overload by adding an additional enum. It has no semantics but helps the compiler to distinguish the different function variants.
