ww3_shel execution with MPI

[jaslanli]

Hello.
I'm trying to follow and apply Inout tutorial, but stuck on executing ww3_shel and not able to get correct out_grd.ww3 and log.ww3 files for proceeding with further steps.
I've completed earlier steps and reached below point (logging on a computation node to run ww3_shel with MPI):

 qsub -I -q mpi_1
 cd $PBS_O_WORKDIR
 mpiexec ww3_shel
 exit

However, when I try, I receive below error:

ja@LM008N:/mnt/c/Users/ja/WW3/build/bin$ qsub -I -q mpi_1
perl: error: resolve_ctls_from_dns_srv: res_nsearch error: Unknown host
perl: error: fetch_config: DNS SRV lookup failed
perl: error: _establish_config_source: failed to fetch config
perl: fatal: Could not establish a configuration source

So, can't run ww3_shel with MPI eventually.
When trying to run it with mpiexec -np 4 ./ww3_shel, mpiexec ./ww3_shel, ./ww3_shel | tee ww3_shel.out program fails as below:

  WAVEWATCH III calculating for 2011/09/02 00:00:00 UTC at 12:40:51

*** WAVEWATCH III WARNING IN W3IOBC :

Abort(1) on node 0: Internal error

I understand that it is because MPI library needs to be used for compiling WW3. In document, it is mentioned that Datarmor HPC is being used for this run and according to previous file , C and Fortran compilers are set with Intel MPI library in Datarmor. However, I'd to know if it is possible to run ww3_shel without MPI, just with ./ww3_shel | tee ww3_shel.out command?
If not, I wonder if someone can guide me to compile WW3 with Intel MPI library.
Currently I have GNU (export CC=gcc, export FC=gfortran)

Thank you in advance!

Hi,

Check the content of the switch file you have used to compile WW3. Using cmake will automatically find the MPI once you provide env variables CC, FC, NetCDF_ROOT correctly.

you can compile ww3 without mpi if you change the keywords "DIST MPI" but "SHRD", then recompile WW3 and you will be able to run ww3_shel directly.

Best,
