* Function: do_copy_objects

* Programmer: Pedro Vicente, pvn@ncsa.uiuc.edu
*
* Date: October, 23, 2003
*
* Modifications:
*
* July 2004: Introduced the extra EC or NN option for SZIP
*
* December 2004: Added a check for H5Dcreate; if the dataset cannot be created
* with the requested filter, use the input one
*
* October 2006: Read/write using the file type by default.
* Read/write by hyperslabs for big datasets.
*
* A threshold of H5TOOLS_MALLOCSIZE (128 MB) is the limit upon which I/O hyperslab is done
* i.e., if the memory needed to read a dataset is greater than this limit,
* then hyperslab I/O is done instead of one operation I/O
* For each dataset, the memory needed is calculated according to
*
* memory needed = number of elements * size of each element
*
* if the memory needed is lower than H5TOOLS_MALLOCSIZE, then the following operations
* are done
*
* H5Dread( input_dataset )
* H5Dwrite( output_dataset )
*
* with all elements in the datasets selected. If the memory needed is greater than
* H5TOOLS_MALLOCSIZE, then the following operations are done instead:
*
* a strip mine is defined for each dimension k (a strip mine is defined as a
* hyperslab whose size is memory manageable) according to the formula
*
* (1) strip_mine_size[k ] = MIN(dimension[k ], H5TOOLS_BUFSIZE / size of memory type)
*
* where H5TOOLS_BUFSIZE is a constant currently defined as 1MB. This formula assures
* that for small datasets (small relative to the H5TOOLS_BUFSIZE constant), the strip
* mine size k is simply defined as its dimension k, but for larger datasets the
* hyperslab size is still memory manageable.
* a cycle is done until the number of elements in the dataset is reached. In each
* iteration, two parameters are defined for the function H5Sselect_hyperslab,
* the start and size of each hyperslab, according to
*
* (2) hyperslab_size [k] = MIN(dimension[k] - hyperslab_offset[k], strip_mine_size [k])
*
* where hyperslab_offset [k] is initially set to zero, and later incremented in
* hyperslab_size[k] offsets. The reason for the operation
*
* dimension[k] - hyperslab_offset[k]
*
* in (2) is that, when using the strip mine size, it assures that the "remaining" part
* of the dataset that does not fill an entire strip mine is processed.
