I admit I haven't searched for nor read information on h5stat. So, if
someone wants to tell me to rtfm, thats fine. Just tell me what to read.
Otherwise, I have some questions interpreting this output from h5stat...
Dataset dimension information:
Max. rank of datasets: 2
Dataset ranks:
# of dataset with rank 1: 188
# of dataset with rank 2: 18
I assume 'rank' is the number of dimensions. right?
1-D Dataset information:
Max. dimension size of 1-D datasets: 9
Ok, this totaly throwse me. What does 'dimension size' mean? It cannot
possibly mean the maximum size of a dimension in 1D datasets as the file
contains 1D datasets of size 1 all the way up to several thousand.
Small 1-D datasets:
# of dataset dimensions of size 1: 45
# of dataset dimensions of size 4: 3
# of dataset dimensions of size 6: 3
# of dataset dimensions of size 8: 3
# of dataset dimensions of size 9: 1
Ditto here. I just don't understand what the above lines are telling me?
How is 'small' defined? Is that controlled by any command-line switch?
Total small datasets: 55
1-D Dataset dimension bins:
# of datasets of size 1 - 9: 55
# of datasets of size 10 - 99: 117
# of datasets of size 100 - 999: 10
# of datasets of size 1000 - 9999: 4
# of datasets of size 10000 - 99999: 1
# of datasets of size 1000000 - 9999999: 1
Total # of datasets: 188
This is great. But, I have 2D datasets also. Why don't I see similar
output for 2D datasets?

Hi Mark,

Yes.

Hmm, it does mean that, so the h5stat tool may have a bug. Are you working with the latest (1.8.4) release?
Small 1-D datasets:
# of dataset dimensions of size 1: 45
# of dataset dimensions of size 4: 3

"small" is <10. It's not a user-tunable request (but I'll file an enhancement request for you

Well, it seemed like it would be much more complex for 2D datasets, since there would be n^2 combinations possible, and n^3 combinations for 3D datasets, etc. I'll file another enhancement request to revisit this idea and see if we can come up with good ways to present the information for 2+ dimension datasets.
