NAME
h5perf_serial: - Measures HDF5 serial performance.
DESCRIPTION
h5perf_serial: Version 1.8.7 usage: h5perf_serial [OPTIONS] OPTIONS -h Print an usage message and exit -A AL Which APIs to test [default: all of them] -c SL Selects chunked storage and defines chunks dimensions and sizes [default: Off] -e SL Dimensions and sizes of dataset [default: 100,200] -i N Number of iterations to perform [default: 1] -r NL Dimension access order (see below for description) [default: 1,2] -t Selects extendable dimensions for HDF5 dataset [default: Off] -v VFD Selects file driver for HDF5 access [default: sec2] -w Perform write tests, not the read tests [default: Off] -x SL Dimensions and sizes of the transfer buffer [default: 10,20] N - is an integer > 0. S - is a size specifier, an integer > 0 followed by a size indicator: K - Kilobyte (1024) M - Megabyte (1048576) G - Gigabyte (1073741824) Example: '37M' is 37 megabytes or 38797312 bytes AL - is an API list. Valid values are: hdf5 - HDF5 posix - POSIX Example: -A posix,hdf5 NL - is list of integers (N) separated by commas. Example: 1,2,3 SL - is list of size specifiers (S) separated by commas. Example: 2K,2K,3K The example defines an object (dataset, tranfer buffer) with three dimensions. Be aware that as the number of dimensions increases, the the total size of the object increases exponentially. VFD - is an HDF5 file driver specifier. Valid values are: sec2, stdio, core, split, multi, family, direct Dimension access order: Data access starts at the cardinal origin of the dataset using the transfer buffer. The next access occurs on a dataset region next to the previous one. For a multidimensional dataset, there are several directions as to where to proceed. This can be specified in the dimension access order. For example, -r 1,2 states that the tool should traverse dimension 1 first, and then dimension 2. Environment variables: HDF5_NOCLEANUP Do not remove data files if set [default remove] HDF5_PREFIX Data file prefix usage: h5perf_serial [OPTIONS] OPTIONS -h Print an usage message and exit -A AL Which APIs to test [default: all of them] -c SL Selects chunked storage and defines chunks dimensions and sizes [default: Off] -e SL Dimensions and sizes of dataset [default: 100,200] -i N Number of iterations to perform [default: 1] -r NL Dimension access order (see below for description) [default: 1,2] -t Selects extendable dimensions for HDF5 dataset [default: Off] -v VFD Selects file driver for HDF5 access [default: sec2] -w Perform write tests, not the read tests [default: Off] -x SL Dimensions and sizes of the transfer buffer [default: 10,20] N - is an integer > 0.
