if the dataset cannot be created * with the requested filter, use the input one * * October 2006: Read/write using the file type by default. * * October 2006: Read 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_dataset1 ) * H5Dread( input_dataset2 ) * * 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. * * November 2006: Use H5Ocopy in the copy of objects. The logic for using * H5Ocopy or not is if a change of filters or layout is requested by the user * then use read/write else use H5Ocopy. * *------------------------------------------------------------------------- */ int do_copy_objects(hid_t fidin, hid_t fidout, trav_table_t *travt, pack_opt_t *options) /* repack options */ { hid_t grp_in=-1;
