Open the file. > > status = nf90_open(trim(input_flnm), NF90_NOWRITE, ncid, & > comm = MPI_COMM_WORLD, & > info = MPI_INFO_NULL) When you pass in the comm and info parameters, you'll end up calling nc_open_par, and that's apparently not valid for a NetCDF3 file... I think if you have configured your NetCDF4 with parallel-netcdf support, then you can read this classic formatted file in parallel. ==rob -- Rob Latham Mathematics and Computer Science Division Argonne National Lab, IL USA
