[MITgcm-support] Reading errors

Hi Martin and Jean-Michel
  I still have the error forrtl: severe (36): attempt to access non-existent record, unit 16, file /bblablabla/run/OBzonalV.bin. In addition, I saw this message after doing make depend f90mkdepend: no source file found for module this. I am no sure if this is important.

I followed your advice. I start doing a simulation in serial mode without obcs and the model ran perfectly fine. Once I opened the obcs (i.e. useOBCS= TRUE), I had that error. Following the architecture of my cluster change a little bit the linux_ia64_ifort. By the way, do I need the last set of conditions of NETCDF_ROOT and netcdf test? I was thinking to remove them.

Kind regards,

Estanis

Hi Estanis,

thanks for the details. This is what I would do:

- At the compile level use a standard build options file, with an intel compiler on a linux system I would start with MITgcm/tools/build_options/linux_amd64_ifort, or linux_ia64_ifort (depending on the output of uname -a, in fact, genmake2 is probably able to pick the correct file if you don?t specify it), and since your domain is small I would first try without MPI, ie. like this:

${somepath}/tools/genmake2 -of ${somepath}/tools/build_options/linux_amd64_ifort -mods ../code
make CLEAN && make depend && make

- With this non-MPI configuration I would try to run the model. First with useOBCS=.FALSE. (just a few timesteps), and then with .TRUE.

- once this works, you can recompile with MPI (if you really need it), like this:

${somepath}/tools/genmake2 -of ${somepath}/tools/build_options/linux_amd64_ifort -mods ../code -mpi
make CLEAN && make depend && make
(note that the extra flag ?-mpi" is enough)

and check if you get the same. For further help, you should record the potential error messages after each step.

Martin

with your grid choice (sphericalPolarGrid), the coriolis parameter is computed and these values are not used.

These files should be found, if they are in the same directory where you run your model. They should each contain (according to you dimensions and time parameters) for 100 timesteps 100 fields of dimension (nx,nz). For anything above 1000 timesteps, they should have 1000 fields (because after the 1000ths record, the model starts from the beginning again, according to you externForcingCycle)

Hi Estanis,

Just a small adjustment:
the standard optfile for intel compiler (version 11 and newer) is:
 linux_amd64_ifort11
in MITgcm/tools/build_options
The optfile "linux_amd64_ifort" is for older version (10 and older).

However, if you are compiling with intel MPI (recent version of the compiler),
then you need to use: linux_amd64_ifort+impi

Cheers,
Jean-Michel
