[External] Re: nf90mpi_get_var_all error code

[Wei-Keng Liao]

Type conversion from double prevision to real*4 should not be the problem.

Please provide the relevant code fragments.
Also, the version of PnetCDF you are using.

Hi Wei-keng,

<https://urldefense.com/v3/__https://www.unidata.ucar.edu/software/netcdf/docs/nc-error-codes.html__;!!Dq0X2DkFhyF93HkjWTBQKhk!CX9PqajQqT-RoOsosnwNBDVNDL_goVYidmpuwfB-vRM9rxzX6NfWmWg-guXf3xpNfJDs$>
Thank you for answer and telling me how to print the error.
Pnetcdf are also using the same error system as netcdf.

Please let me share the information below for reference.
https://www.unidata.ucar.edu/software/netcdf/docs/nc-error-codes.html


Here is the header of my netcdf file:

netcdf clim_aerosol_BC {
dimensions:
         month = 12;
         nlev = 16;
         ncol = 3110402;
variables:
         float BC(month, nlev, ncol);
         double pressure(nlev);
}

Trying to read the second pressure variable,
I confirmed that it goes into nf90mpi_get_var_all(0, 2, VAR, 1, 16).
I thought it was a problem because VAR is a real4 variable, so I changed the pressure of the netcdf file from double to float, but it is the same.
I am now in doubt whether there was a problem with the library installation process.

Any idea what's wrong?

Kihang

Subject: [External] Re: nf90mpi_get_var_all error code

API nf90mpi_strerror() can be used to obtain the error message, for example

  err = nf90mpi_get_var_all(ncid, varid, buf, start, count)
  write(6,*) "Error when calling nf90mpi_get_var_all ", trim(nf90mpi_strerror(err))

Error code -40 is constant NF90_EINVALCOORDS, which corresponds to the message below.
   NetCDF: Index exceeds dimension bound

Check the argument "start" for invalid values used.

Hi,

I try to read the contents of Netcdf file with nf90mpi_get_var_all, but I get an error code of -40.
I want to debug that content, how can I do it?
Please tell us if there is a way to find out what the error code means for each function.
Even a little thing you know will be of great help to me.

Best Regards,
Kihang
