PIO version?

[mark@atmos_colostate_edu]

I'm in dire need of running a legacy version of CESM (svn checkout https://svn-ccsm-models.cgd.ucar.edu/cesm1/exp_tags/cesm1_3_aofluxd02/), but unfortunately this subversion command ends with an error saying that certain external definitions were not processed:

svn: E205011: Failure occurred processing one or more externals definitions

and it appears one of the missing pieces was the pio source. Would anyone know which version of pio might work with this particular version of cesm1_3? I tried the pio code from cesm1.2.2 and also cesm1_3_beta18 but they both fail build.

Also, for a given cesm distribution, how can you tell which version of pio that you have?

Thanks,
Mark Branson

Hi Mark,

GitHub - NCAR/ParallelIO at pio1_8_14

A high-level Parallel I/O Library for structured grid applications - GitHub - NCAR/ParallelIO at pio1_8_14

github.com

should work with that version of cesm - fair warning nether the cesm or pio version are officially supported.

Thanks so much, Jim. I'll cross my fingers and give it a whirl.

I know this is not a supported version anymore but just in case there's an easy answer for this: I'm trying to compile this on Derecho and the pio build log says:

CMake Error at /glade/derecho/scratch/branson/F_AMIP/bld/pio/tryCompileCSIZEOF/CMakeFiles/CMakeTmp/CMakeLists.txt:17 (add_executable):


Cannot find source file:

//TryCSizeOf.f90

It seems like it would be a incorrect or missing path somewhere because that test program does exist in the CMake directory, but I can't seem to find where it tries to get this path.

Make sure you have this repo GitHub - CESM-Development/CMake_Fortran_utils: CMake modules dealing with Fortran-specific issues and Fortran libraries
checked out in a cmake subdirectory.

 

[mark@atmos_colostate_edu]

Thanks. Yeah, the CMake directory was missing when I checked out this tag, but I grabbed that before I created the case.

In the Makefile /glade/u/home/branson/cesm1_3_aofluxd02/scripts/F_AMIP/Tools/Makefile
Add a -DUSER_CMAKE_MODULE_PATH= path/to/that/cmake/directory
at line 483

Awesome. Now we're getting a little bit further. The new error in the PIO build file is:

CMake Error at CMakeLists.txt:190 (ADD_LIBRARY):
Target "pio" links to item " -LNETCDF_LIB_DIR-NOTFOUND -lnetcdf" which has
leading or trailing whitespace. This is now an error according to policy
CMP0004.

Which makes me suspect that the netcdf library path is incorrect or missing somewhere.

 

[mark@atmos_colostate_edu]

On a whim I hacked FindNETCDF.cmake and added this line:
set(NETCDF_FORTRAN_LIB_DIR /glade/u/apps/derecho/23.06/spack/opt/spack/netcdf/4.9.2/oneapi/2023.0.0/iijr/lib)

and now the entire model compiles (it's an F_AMIP case) but then at the link step I'm getting a ton of undefined symbols.
chem_surfvals.F90:(.text+0x1a55): undefined reference to `netcdf_mp_nf90_get_var_1d_fourbyteint_'


ld: chem_surfvals.F90:(.text+0x1c29): undefined reference to `netcdf_mp_nf90_get_var_1d_eightbytereal_'


ld: chem_surfvals.F90:(.text+0x1c79): undefined reference to `netcdf_mp_nf90_get_var_1d_eightbytereal_'

...
ad nauseam.

So maybe the pio compile still needs some work???

Try adding -lnetcdff -lnetcdf to your link line.

That did it! cesm.exe has been successfully created!!!

Thank you so much, Jim. As always, YOU DA MAN! :)
