Detailed Description

template<class Scalar, class Ordinal>
class Tpetra::MatrixMarket::Raw::Reader< Scalar, Ordinal >

"Raw" reader for debugging a Matrix Market file.

This class' methods are useful for examining the contents of a Matrix Market file, and checking the integrity of its data. See MatrixMarket_Tpetra.hpp for a Matrix Market reader that constructs a Tpetra::CrsMatrix object.

template<class Scalar , class Ordinal >

static bool Tpetra::MatrixMarket::Raw::Reader< Scalar, Ordinal >::readFile	(	const Comm< int > &	comm,
		const std::string &	filename,
		const bool	echo,
		const bool	tolerant,
		const bool	debug = false
	)		[inline, static]

Read the sparse matrix from the given file.

This is a collective operation. Only Rank 0 opens the file and reads data from it, but all ranks participate and wait for the final result.

Note:

This whole "raw" reader is meant for debugging and diagnostics of syntax errors in the Matrix Market file; it's not performance-oriented. That's why we do all the broadcasts of and checks for "success".
