h5perf_serial: - Measures HDF5 serial performance.
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
