template<class Ordinal , class Scalar , class TimerType >

TSQR::Test::DistTsqrBenchmarker< Ordinal, Scalar, TimerType >::DistTsqrBenchmarker	(	const Teuchos::RCP< MessengerBase< Scalar > > &	scalarComm,
		const Teuchos::RCP< MessengerBase< double > > &	doubleComm,
		const std::vector< int > &	seed,
		const std::string &	scalarTypeName,
		std::ostream &	out,
		std::ostream &	err,
		const bool	testFactorExplicit,
		const bool	testFactorImplicit,
		const bool	humanReadable,
		const bool	debug
	)		[inline]

Constructor, with custom seed value.

Parameters:

scalarComm	[in/out] Communicator object over which to test.
doubleComm	[in/out] Communicator object for doubles, used for finding the min and max of timing results over all the MPI processes.
seed	[in] 4-element vector; the random seed input of TSQR::Random::NormalGenerator (which see, since there are restrictions on the set of valid seeds)
scalarTypeName	[in] Human-readable name of the Scalar template type parameter
out	[out] Output stream to which to write results
err	[out] Output stream to which to write any debugging outputs (if applicable) or errors
testFactorExplicit	[in] Whether to test DistTsqr::factorExplicit()
testFactorImplicit	[in] Whether to test DistTsqr::factor() and DistTsqr::explicit_Q()
humanReadable	[in] Whether printed results should be easy for humans to read (vs. easy for parsers to parse)
debug	[in] Whether to write verbose debug output to err

		const bool	testFactorExplicit,
		const bool	testFactorImplicit,
		const bool	humanReadable,
		const bool	debug
	)		[inline]

Constructor, with default seed value.

This constructor sets a default seed (for the pseudorandom number generator), which is the same seed (0,0,0,1) each time.

Parameters:

scalarComm	[in/out] Communicator object over which to test.
doubleComm	[in/out] Communicator object for doubles, used for finding the min and max of timing results over all the MPI processes.
scalarTypeName	[in] Human-readable name of the Scalar template type parameter
out	[out] Output stream to which to write results
err	[out] Output stream to which to write any debugging outputs (if applicable) or errors
testFactorExplicit	[in] Whether to test DistTsqr::factorExplicit()
testFactorImplicit	[in] Whether to test DistTsqr::factor() and DistTsqr::explicit_Q()
humanReadable	[in] Whether printed results should be easy for humans to read (vs. easy for parsers to parse)
debug	[in] Whether to write verbose debug output to err

void TSQR::Test::DistTsqrBenchmarker< Ordinal, Scalar, TimerType >::getSeed

(

std::vector< int > &

seed

)

const [inline]

Get seed vector for pseudorandom number generator.

Fill seed (changing size of vector as necessary) with the seed vector used by the pseudorandom number generator. You can use this to resume the pseudorandom number stream from where you last were.

Definition at line 505 of file Tsqr_ParTest.hpp.

template<class Ordinal , class Scalar , class TimerType >

void TSQR::Test::DistTsqrBenchmarker< Ordinal, Scalar, TimerType >::benchmark	(	const int	numTrials,
		const Ordinal	numCols
	)		[inline]

Run the DistTsqr benchmark.

Parameters:

numTrials	[in] Number of times to repeat the computation in a single timing run
numCols	[in] Number of columns in the matrix to test. Number of rows := (# MPI processors) * ncols
