h5perf_serial
[options]
h5perf_serial
provides tools for testing the performance
of the HDF5 Library in serial mode.
See “h5perf_serial, a Serial File System Benchmarking Tool” for a complete description of this tool.
The following environment variable can be set to control the
specfied aspect of h5perf_serial
behavior:
HDF5_NOCLEANUP
|
If set, h5perf_serial does not remove data files.
(Default: Data files are removed.) | ||
HDF5_PREFIX
| Sets the prefix for output data files. |
K
for kilobytes (1024 bytes)
M
for megabytes (1048576 bytes)
G
for gigabytes (1073741824 bytes)
37M
specifies 37 megabytes or
38797312 bytes.
-A api_list
|
Specifies which APIs to test. api_list
is a comma-separated list with the following valid values:
Example: |
||||||
-c chunk_size_list
| Specifies chunked storage
and defines chunks dimensions and sizes.
(Default: Chunking is off.)
chunk_size_list is a comma-separated list of
size specifiers.
For example, a chunk_size_list value of
|
||||||
-e dataset_size_list
| Specifies dataset dimensionality
and dataset dimension sizes.
(Default dataset size is 100x200, or 100,200 .)
dataset_size_list is a comma-separated list of size specifiers, which are defined above.
For example, a dataset_size_list value of
|
||||||
-i iterations
| Specifies the number of iterations to perform.
(Default: A single iteration, 1 , is performed.)
iterations is an integer specifying the number of iterations. |
||||||
-r access_order
| Specifies dimension access order.
(Default: 1,2 )
access_order is a comma-separated list of
integers specifying the order of access.
For example,
|
||||||
-t
| Selects extendable HDF5 dataset dimensions.
(Default: Datasets are fixed size.)
|
||||||
-v file_driver
| Selects HDF5 driver to be used for HDF5 file access.
(Default: sec2 )
Valid values are as follows:
|
||||||
-w
| Specifies the performance of write tests only,
read performance will not be tested.
(Default: Both write and read tests are performed.) |
||||||
-x buffer_size_list
| Specifies transfer buffer dimensions and sizes.
(Default: 10,20 )
|
0 | Succeeded. |
>0 | An error occurred. |
