32
33       -x SL  Dimensions and sizes of the transfer buffer [default: 10,20]
34
35       N      - is an integer > 0.
36
37       S      - is a size specifier, an integer > 0 followed by a size indica‐
38              tor:
39
40              K -  Kilobyte  (1024)  M  -  Megabyte  (1048576)  G  -  Gigabyte
41              (1073741824)
42
43              Example: '37M' is 37 megabytes or 38797312 bytes
44
45              AL - is an API list. Valid values are:
46
47              hdf5 - HDF5 posix - POSIX
48
49              Example: -A posix,hdf5
50
51              NL - is list of integers (N) separated by commas.
52
53              Example: 1,2,3
54
55              SL - is list of size specifiers (S) separated by commas.
56
57              Example: 2K,2K,3K
58
59              The  example  defines  an  object (dataset, tranfer buffer) with
60              three dimensions. Be aware that  as  the  number  of  dimensions
61              increases,  the  the total size of the object increases exponen‐
62              tially.
63
64       VFD    - is an HDF5 file driver specifier. Valid values are:
65
66              sec2, stdio, core, split, multi, family, direct
67
68              Dimension access order:
69
70              Data access starts at the cardinal origin of the  dataset  using
71              the  transfer buffer. The next access occurs on a dataset region
72              next to the previous one. For a multidimensional dataset,  there
73              are several directions as to where to proceed. This can be spec‐
74              ified in the dimension access order. For example, -r 1,2  states
75              that the tool should traverse dimension 1 first, and then dimen‐
76              sion 2.
77
78              Environment variables:
79
80       HDF5_NOCLEANUP
81              Do not remove data files if set [default remove]
82
83       HDF5_PREFIX
84              Data file prefix
