addReport()

template<typename Duration>

void openPMD::MPIBenchmarkReport< Duration >::addReport	(	int	rootThread,
		std::string	jsonConfig,
		std::string	extension,
		int	threadSize,

Add results for a certain compression strategy and level.

Parameters

rootThread	The MPI rank which will collect the data.
jsonConfig	Compression strategy.
extension	The openPMD filename extension.
threadSize	The MPI size.
dt	The openPMD datatype.
iterations	The number of iterations per compression strategy.
report	A pair of write and read time measurements.

getReport()

template<typename Duration>

std::pair< Duration, Duration > openPMD::MPIBenchmarkReport< Duration >::getReport	(	int	rank,
		std::string	jsonConfig,
		std::string	extension,
		int	threadSize,
		Datatype	dt,
		Series::IterationIndex_t	iterations )

Retrieve the time measured for a certain compression strategy.

Parameters

rank	Which MPI rank's duration results to retrieve.
jsonConfig	Compression strategy.
extension	The openPMD filename extension.
threadSize	The MPI size.
