/* The SWMR data arrays:
|
|
*
|
|
* The code uses a 2-D jagged array of datasets. The first dimension is called
|
|
* the 'level' and there are five of them.
|
|
*
|
|
* #define NLEVELS 5
|
|
*
|
|
* The second dimension is the 'count' and there are quite a few datasets per
|
|
* 'level'.
|
|
*
|
|
* unsigned symbol_count[NLEVELS] = {100, 200, 400, 800, 1600};
|
|
*
|
|
* These datasets are created when the skeleton is generated and are initially
|
|
* empty. Each dataset has no upper bound on size (H5S_UNLIMITED). They
|
|
* are of compound type, with two members: an integer ID and an opaque
|
|
* 'data part'. The data part is not used by the SWMR testing.
|
|
*
|
|
* The SWMR testing will then randomly add and/or remove entries
|
|
* from these datasets. The selection of the level is skewed by a mapping
|
|
* table which preferentially hammers on the lower levels with their smaller
|
|
* number of datasets.
|
|
*
|
|
* static unsigned symbol_mapping[NMAPPING] = {0, 0, 0, 0, 1, 1, 2, 3, 4};
|
|
*
|
|
* The information about each dataset (name, hid_t, etc.) is stored in a
|
|
* separate array.
