Hi Ajit, > Does NetCDF 4.x have a specific requirement for the latest HDF5 > release (1.8.3)? Or can we simply go with 1.8.2? You can just use 1.8.2, as far as I know. > I know HDF5 versions 1.8.2 to 1.8.3 may have some > fixes/enhancements, but as long as we are not directly dealing with > the HDF5 API, I was curious whether NetCDF 4.x requires the latest > HDF5 for all its 4.x features to be activated. No, if it depends on anything from later than 1.8.1, it's a bug. There was a significant performance bug when accessing compressed or chunked data that was fixed in 1.8.3, but the somewhat slower results using 1.8.2 were still correct. > Even if there is no current need for the latest HDF5, I will rely on > your NetCDF web pages to suitably warn us if a specific version is > needed. That sounds good, and we'll announce such dependencies to the address@hidden mailing list as well, if they are required. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: CYF-313110 Department: Support netCDF Priority: Normal Status: Closed
