[MITgcm-devel] llc90 set-up

[Manfredi Manizza]

Hi,

I am trying to set-up the new llc90 config from Gael
following the readme file here below.

I have problem :

After this command of STEP 2 :

> source ./setup_these_exps.csh

I have got this :

mkdir: cannot create directory `global_oce_tmp_download': File exists
cvs checkout: No CVSROOT specified!  Please use the `-d' option
cvs [checkout aborted]: or set the CVSROOT environment variable.
cvs checkout: No CVSROOT specified!  Please use the `-d' option
cvs [checkout aborted]: or set the CVSROOT environment variable.
mv: cannot stat `MITgcm_contrib/gael/verification/global_oce_cs32': No 
such file or directory
mv: cannot stat `MITgcm_contrib/gael/verification/global_oce_llc90': No 
such file or directory
--2013-01-24 16:47:53-- 
http://mitgcm.org/~gforget/global_oce_input_fields.tar.gz

then I managed to downlaod only the forcing files

So the two folders global_oce_cs32 and global_oce_llc90 (correct ??) are 
not created...


I do not understad the message on the -d option. Does it refer to CVS at 
the beinning when I download the entire tree code ?

Can somebody help me with that ?

I hope I did not say something too naive...

Thanks in advance
Manfredi

---------------------------------------------------------------
A) setup the experiments (incl. llc90 and cs32 core2.cnyf runs)
---------------------------------------------------------------

0) get MITgcm as explained @ http://mitgcm.org/public/source_code.html
1) the following assumes that you are in directory MITgcm/verification/
    i.e., after checkout of the model repository, do:
       cd MITgcm/verification/
    from here, get the 
MITgcm_contrib/gael/verification/setup_these_exps.csh
    c-shell setup script e.g. by typing
       cvs co MITgcm_contrib/gael/verification/setup_these_exps.csh
       mv MITgcm_contrib/gael/verification/setup_these_exps.csh .
    Unless you already had something in MITgcm_contrib you may want
    to remove that directory. Hereafter we wont need it anymore.
2) execute the setup script by typing
       source ./setup_these_exps.csh
    A pre-requisite is that you are logged in to the MITgcm
    cvs server. If you completed step1, you indeed already are.
    If otherwise, see http://mitgcm.org/public/source_code.html
3) step2 creates a directory global_oce_tmp_download that
    contains the experiments directories. Move them (incl.
    global_oce_input_fields) to MITgcm/verification and cd to
    that location. Once you have done this succesfully you may want
    to remove global_oce_tmp_download. We wont need it anymore.
4) exectute MITgcm with testreport. Two examples from one machine.
    To run the cs32 test on one cpu :
        ./testreport -t global_oce_cs32
    And to run the llc90 test on 12 cpus, using mpi
       ./testreport -match 6 
-of=../tools/build_options/linux_amd64_gfortran -MPI 12 -command 'mpirun 
-np TR_NP
ROC ./mitgcmuv' -t global_oce_llc90
    The optfile may be swaped for one that better suits your machine.
5) for llc90 experiment testreport should show something like
     Y Y Y Y> 6<16 16 12 12 16 16 13 11 12 11 11 11 12 13 10 11  .  . pass 
global_oce_llc90
     Y Y Y N .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. ..  .  . N/O 
global_oce_llc90.core2
     Y Y Y N .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. ..  .  . N/O 
global_oce_llc90.ecco_v4
     Y Y Y N .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. ..  .  . N/O 
global_oce_llc90.ecmwf
    implying that the main experiment ran as expected in 
global_oce_llc90/run. In contrast
    the sub-experiments, by default, fail by omission of surface forcing 
fields. This
    omission saves disk space and download time. In case you want to run 
the sub-experiments,
    you will need to obtain additional inputs. Contact us about this if 
applies.
