	)		[inline, static]

Establish baseline for OrthoManager benchmark.

Establish baseline for the orthogonalization manager benchmark, by replacing the projection and normalization operations with the same number of copies.

template<class Scalar , class MV >

static void Belos::Test::OrthoManagerBenchmarker< Scalar, MV >::benchmark	(	const Teuchos::RCP< OrthoManager< Scalar, MV > > &	orthoMan,
		const std::string &	orthoManName,
		const std::string &	normalization,
		const Teuchos::RCP< const MV > &	X,

	)		[inline, static]

Benchmark the given orthogonalization manager.

Parameters:

orthoMan	[in(/out)] The orthogonalization manager to benchmark
orthoManName	[in] Name of the orthogonalization manager (e.g., "TSQR", "ICGS", "DGKS")
normalization	[in] Normalization scheme used by the orthogonalization manager (only applicable to the "Simple" orthogonalization)
X	[in] "Prototype" multivector; not modified
numCols	[in] Number of columns per block
numBlocks	[in] Number of blocks
numTrials	[in] Number of trials in the timing run
outMan	[out] Output manager
resultStream	[out] Output stream for printing benchmark results. If displayResultsCompactly is true, it will be written by all MPI rank(s), so on ranks other than 0, it should be set appropriately to a "black hole stream" that doesn't write anything.
displayResultsCompactly	[in] If false, rely on TimeMonitor::summarize() to print results to resultStream (and ensure only MPI Rank 0 does so). If true, print results in a more compact format suitable for automatic parsing, using a CSV (Comma-Delimited Values) parser. In "compact" mode, two lines are printed, both of which are comma-delimited ASCII text. The first line begins with a "comment" character #; following that are column ("field") labels. The second line contains the actual data, again in ASCII comma-delimited format.
