MPIOM in COSMOS-1.0.0
./Create_TASKS.frm cosmos-ao test1
In case you want to run the default setting just edit the file
$MYDIR/cosmos-1.0.0/util/running/setup/setup_cosmos-ao_test1
and set your email adress. Type
./Create_TASKS.frm cosmos-ao test1
a second time. Otherwise you have to edit the file
$MYDIR/cosmos-1.0.0/util/running/setup/setup_cosmos-ao_test1
further, according to your planned experimental setup.
Then change into
$MYDIR/cosmos-1.0.0/experiments/test1/scripts
and start the model run by submitting test1.run:
qsub test1.run
ATTENTION: Before starting productions runs please set
the following switch in the script test1.run:
nlogprt=0 (instead of 2)
and comment the lines
#export F_SETBUF06=0
#export F_SETBUF07=0
#export F_SETBUF08=0
This enhances the models performance. These settings are
only necessary during the testphase.
You can get more information on the usage of Create_TASKS.ksh with
./Create_TASKS.ksh --help

DATA on NEC
-----------
For the directory structure, where to find your data etc., please look
into the $MYDIR/util/running/doc/prism_rep05.pdf, fig 2.1
RUNNING with OpenMP
-------------------
Running the model with OpenMP requires additional compiler options.
You have to edit the compile scripts produced by Create_COMP_cpl_models.ksh:
Set the switch "compile_with_OpenMP" from no to yes before compiling
(necessary in COMP_echam5_test1.ksh and COMP_mpiom_test1.ksh).
When you prepare the run scripts using Create_TASKS.frm you have to
edit the setup file and set the variables nthreadatm and nthreadoce
accordingly.
Platforms
---------
The model has been testet on the SX-6 in Hamburg (SUPER UX 16.1,
sxf90 Rev.340, sxc++ Rev.072) both in T31L19/GR30L40 and T63L31/GR15L40
resolution.
The model runs with MPI1 (default) or MPI2 and hybrid (MPI1/OpenMP, MPI2/OpenMP).
Note that the included SRE and SCE header files for Sunos and Linux
are not tested, they could however help in case the cosmos model is
installed on these platforms.
Postprocessing
--------------
QUICKplots.tar is a standard postprocessing tool for ECHAM-output.
Untar the file and follow the README.
