◆ initInputData()

void benchmarks::exahype2::kernelbenchmarks::initInputData	(	SolverPrecision *	Q,
		const tarch::la::Vector< DIMENSIONS, double >	CellCenter,
		const tarch::la::Vector< DIMENSIONS, double >	CellSize
	)

Set input data.

We use the values from the centralMost Cell in the domain with an arbitrary cell size of 1/81 of the domain size.

TODO: should we update this to actual initial conditions?

◆ reportRuntime()

void benchmarks::exahype2::kernelbenchmarks::reportRuntime	(	const std::string &	kernelIdentificator,
		const tarch::timing::Measurement &	timingComputeKernel,
		const tarch::timing::Measurement &	timingKernelLaunch,
		int	numberOfCells,
		int	numberOfThreads,
		tarch::logging::Log	_log
	)

Reports the runtime and throughput of the benchmarks.

First set of outputs refers to the time of the compute kernel itself. Second set of outputs refers to the time including the kernel launch overhead. The throughput is measured in the updates of volumes per second (dof/s).

In the second part, this also writes the information about the runtime to a csv file
