You will need a desktop running a 64 bit version of Linux. In addition you will need access to /ford1/local and /ford1/share from your desktop. GMAO support can help you with these items. If you want to run the full model you will need one of the newer 8 core (with hyperthreading) machines with 8 GB of memory. The single column model can be run on one of the older machines with less cores and memory. | You will need a desktop running a 64 bit version of Linux. In addition you will need access to /ford1/local and /ford1/share from your desktop. The ford1 disk contains the libaries, baselibs, and boundary conditions needed to run the model.

$ cvs co -r Ganymed-4_0_BETA3 Ganymed | $ cvs co -r Ganymed-4_0_BETA3 Ganymed | ||

You then need to update a few files. Issue to following command in the src directory to update these 4 files | |||
<pre> | |||
$ cvs upd -r mat-G40B3-desktop g5_modules Applications/GEOSgcm_App/gcm_convert.j Applications/GEOSgcm_App/gcm_setup Applications/GEOSgcm_App/scm_setup | |||
</pre> | |||
Once this is done you can build the model as usual. Make sure that the environment variable ESMADIR is set, this will be path_model/GEOSagcm. Then | |||
<pre> | |||
source $ESMADIR/src/g5_modules. | |||
</pre> | |||
and issue the make. You can and should use the parallel build up to the number of cores you have available. To build using 4 cores you would issue: | |||
<pre> | |||
make -j10 pinstall | |||
</pre> | |||
Assuming everything goes right you should have a functional GEOS 5 model. | |||
