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
-AAL- Which APIs to test [default: all of them]
-cSL- Selects chunked storage and defines chunks dimensions and sizes [default: Off]
-eSL- Dimensions and sizes of dataset [default: 100,200]
-iN- Number of iterations to perform [default: 1]
-rNL- Dimension access order (see below for description) [default: 1,2]
-t- Selects extendable dimensions for HDF5 dataset [default: Off]
-vVFD- Selects file driver for HDF5 access [default: sec2]
-w- Perform write tests, not the read tests [default: Off]
-xSL- 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:
-Aposix,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,
-r1,2 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
