Hi Kent:

So do you think no one will use this particular format? If so, I will wait for new version..

I don't know. Somebody from OU contacted with me about using WRF-PHDF5. But I didn't hear from them about this issue.

since its also in the sequential version, i guess the question is, do you know if WRF is planning on using either version?

BTW, in the parallel output (but not the sequential), you put each time step in its own group. was this to optimize parallel performance or something ?

The reason is: we are using contiguous storage for parallel HDF5 because of performance issue. So that's why we put each time step in to its own group. I hope that in the future I can have time or maybe a little funding to modify the WRF-HDF5 IO modules with 1.8 release.

so you use contiguous, not chunked storage. so you cant extend the data ? so you create a new group as each time step completes ? how do you parellelize the tasks? does each thread have its own seperate region of the array?
