Hi,

I have some questions about parallel netCDF4 (using HDF5, not PnetCDF). 
I think it's best to just ask them, so please excuse the long list :

1) What is its strategy for parallel I/O ?
2) How is it related to HDF5 ? Is it just a wrapper around it ?
3) When writing a netCDF4 file, is it really netCDF or is it HDF5 ?
ncdump -k returns "netCDF4" but I am not sure.
4) Is there some documentation online ? I only found that :
http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-tutorial/Parallel.html
which is very light.
5) Any references (paper or benchmarks) are welcomed. At the moment, I only
found the paper by Li et al. (2003) about PnetCDF.

Cheers,
