Submitting jobs to Cooley is done from the login machines (hostname cooley.alcf.anl.gov) using the Cobalt batch scheduler. Access to theses machines is done via ssh using two-factor authentication. Thus, submission and management of Cooley jobs must be done by a human who has a login account.
+Before submitting Cooley jobs, a CHTC staff member must configure the SoftEnv system so that the proper CUDA libraries can be found by HTCondor and user jobs. To do so, they must create the file =~/.soft.cooley= with the following contents:
+{code}
++mvapich2
++cuda-9.0.176
+@default
+{endcode}
+
Once logged into a Cooley login machine, a CHTC staff member can submit a new hobble-in job with a command like this:
{code}
% /home/jfrey/hobblein/bin/hobblein_submit 2 24:00:00 Test1 jfrey
