Detailed Description

: class IJK_Striped_Writer

Converts the input field to a linear lexicographic file written with optimized striping for lustre filesystem (splits the data into chunks of size "stripesize", give the chunks to different nodes of the MPI job and each node writes some of the chunks to maximize bandwidth). striping not yet implemented, all data is collected on the master node !

template<typename _OUT_TYPE_, typename _TYPE_, typename _TYPE_ARRAY_>

void IJK_Striped_Writer::redistribute	(	const IJK_Field_template< _TYPE_, _TYPE_ARRAY_ > &	input,

		const int	nktot,
		const int	nbcompo,

Redistribute data from input (distributed ijk scalar field) to ouput (striped linear storage) output is a 'big' array (might contain more than 32b) les n_compo_tot sont inutiles ici !!!
