Detailed Description

A concrete HDF5 data writer class.

Definition at line 55 of file Hdf5DataWriter.hpp.

Constructor & Destructor Documentation

Hdf5DataWriter::Hdf5DataWriter	(	DistributedVectorFactory &	rVectorFactory,
		const std::string &	rDirectory,
		const std::string &	rBaseName,
		bool	cleanDirectory = `true`,
		bool	extendData = `false`,
		std::string	datasetName = `"Data"`
	)

Constructor.

Parameters

rVectorFactory	the factory to use in creating PETSc Vec and DistributedVector objects.
rDirectory	the directory in which to write the data to file, relative to chaste test output.
rBaseName	the name of the file in which to write the data
cleanDirectory	whether to clean the directory (defaults to true)
extendData	whether to try opening an existing file and appending to it.
datasetName	The name of the HDF5 dataset to write, defaults to "Data".

The extendData parameter allows us to add to an existing dataset. It only really makes sense if the existing file has an unlimited dimension which we can extend. It also only makes sense if cleanDirectory is false, otherwise there won't be a file there to read...

Todo:: 1300 We can't set mDataFixedDimensionSize, because the information isn't in the input file. This means that checking the size of input vectors in PutVector and PutStripedVector is impossible.

Member Function Documentation

void Hdf5DataWriter::AdvanceAlongUnlimitedDimension ( )

Advance along the unlimited dimension. Normally this will be called when all variables in a row have been input.

bool Hdf5DataWriter::ApplyPermutation	(	const std::vector< unsigned > &	rPermutation,
		bool	unsafeExtendingMode = `false`
	)

Apply a permutation to all occurences of PutVector Should be called when in define mode

Parameters

rPermutation	a forward/?reverse permutation
unsafeExtendingMode	is true when we are extending a file which requires a permutation to be applied to it. In particular we are extending a cardiac simulation with "original node ordering"

Returns: success value. A value "false" indictates that the permutation was empty or was the identity and was not applied

		unsigned *	pChunkSizeInBytes,
		bool *	pAllOneChunk
	)

private

Calculate (and save in the member variables) chunk dimensions based on a target size. Chunks are kept as "square" as possible while wasting as little space around the edges of the dataset as possible.

Parameters

[in]	targetSize	The target number of entries in each dimension in the chunk.
[out]	pChunkSizeInBytes	The size of the resulting chunk in bytes.
[out]	pAllOneChunk	Whether the dataset is spanned by a single chunk.

void Hdf5DataWriter::SetChunkSize ( )

private

This method sets the chunk size by building up in each dimension until a threshold is reached, unless user-specified values have been set using SetFixedChunkSize. By default, chunks of 128 K are used, which seems to be a good compromise. For large problems performance will usually improve by increasing this value (to e.g. 1 M).

void Hdf5DataWriter::SetFixedChunkSize	(	const unsigned &	rTimestepsPerChunk,
		const unsigned &	rNodesPerChunk,
		const unsigned &	rVariablesPerChunk
	)

Use a particular chunk size, ignoring the algorithm that figures out a sensible value.

This method may be useful in very specific circumstances, e.g. if you want chunks to align perfectly with stripes on a Lustre file system, or if you have a parallel problem where every process can be assigned the same size and shape hyperslab of the HDF5 file (thus getting rid of contention between processes when reading/writing).

USE WITH CAUTION - as it can degrade performance.

Parameters

rTimestepsPerChunk	The number of unlimited dimension steps (usually time steps) per chunk.
rNodesPerChunk	The number of objects (usually nodes) per chunk in the second dimension.
rVariablesPerChunk	The number of objects (usually output variables) per chunk in the third dimension.
