[netcdfgroup] Are concurrent readers/writers save with nc4?
Hi,
I'm a bit puzzled by the information available about concurrent
readers/writers and netcdf4(hdf5) files.
My case:
Writer: A model, which opens the netcdf file every timestep and writes
the timestep to the file, closing the file afterwards.
Reader: Wants to access the already written timesteps (e.g. known from a
log-file). Reads those, and closes the file afterwards.
Reader and Writer work concurrently on the same file, eventually on
different machines (NFS). This worked well with netcdf3 files, but I'm
not sure if this is safe with netcdf4. Do we need to take some
precautions concerning compression/chunking?
Best wishes,
Heiko
