Hi,
I'm interested in being able to change the cache settings for chunks in HDF5.
For this, I plan to call:
{{{
herr_t H5Pset_cache(hid_t plist_id, int mdc_nelmts, size_t rdcc_nelmts,
size_t rdcc_nbytes, double rdcc_w0)
}}}
before opening an HDF5 file.
Most of the parameters of the H5Pset_cache call are clear, but I cannot
determine a good default for rdcc_nelemts. From the manual:
{{{
The number of elements (objects) in the raw data chunk cache is rdcc_nelmts.
The total size of the raw data chunk cache and the preemption policy are
rdcc_nbytes and rdcc_w0, respectively.
}}}
I'm choosing 10 by default at this time, but I'd be grateful if anybody can
tell me whether this is a decent value or not (and the rational behind this).
Cheers,
