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
