The commands below assume that your shell is <code>csh</code>.  Since the scripts to build and run GEOS-5  tend to be written in the same, you shouldn't bother trying to import too much into an alternative shell.  If you prefer a different shell, it is easiest just to open a <code>csh</code> process to build the model and your experiment.

==== CVS Errors ====


If the CVS checkout doesn't work for you, there are many possibilities. If the error says something about "keyupload", then the key upload either hasn't taken hold yet (can take 5-10 minutes to work after uploading the key), or, perhaps, the wrong key was uploaded.

===== Keyupload =====
 
If the error says something about "keyupload", then the key upload either hasn't taken hold yet (can take 5-10 minutes to work after uploading the key), or, perhaps, the wrong key was uploaded.
 
===== Access denied for this host =====


If you see something like "access denied for this host", then your best bet is to contact NCCS. Per a response from NCCS to a user that had something similar happen, they need to add the CVS hosts to an LDAP entry.

===== Failed to create lock/permission denied =====
If you see something like:
cvs checkout: failed to create lock directory for `/cvsroot/esma/CVSROOT' (/cvsroot/esma/CVSROOT/#cvs.history.lock): Permission denied
cvs checkout: failed to obtain history lock in repository `/cvsroot/esma'
cvs checkout: Updating src
cvs checkout: failed to create lock directory for `/cvsroot/esma/esma/src/Applications/GEOSdas' (/cvsroot/esma/esma/src/Applications/GEOSdas/#cvs.lock): Permission denied
cvs checkout: failed to obtain dir lock in repository `/cvsroot/esma/esma/src/Applications/GEOSdas'
cvs [checkout aborted]: read lock failed - giving up
this means you don't have a home directory on progress. Try doing:
$ ssh progress.nccs.nasa.gov
You'll enter your PASSCODE and password and then it'll seem like the terminal is "stuck". Just hit Ctrl-C. Now try the CVS command again.

This will build the model.  It will take about 30 minutes.  If this works, it should create a directory under <code>GEOSagcm</code> called <code>Linux/bin</code>.  In here you should find the executable: <code>GEOSgcm.x</code> .

GEOS-5 has moved to using SGI MPT by default at NCCS. This means the model '''CANNOT be built on Dali'''. You can build the model on any Discover head node or any Haswell compute node.
