Submission utility
To ease the transition to the new cluster and the general use of HTCondor, we implemented a solution based on environment modules. The traditional interaction methods, i.e. specifying all command line options, remain valid, yet less handy and more verbose.
The htc modules will set all environment variables needed to correctly submit to both the old and the new HTCondor clusters.
Once logged into any Tier 1 user interface, this utility will be available. You can list all the available modules using:

These htc/* modules have different roles:
- htc/local - to be used once you want to submit jobs to or query the local schedds sn-02 or sn01-htc, respectively the HTCondor 9.0 and 23 cluster access points. This is the default module loaded when loading the "htc" family.

Local Submission
To submit local jobs, the behavior is the same as for HTCondor 9 using the Jobs UI.
- Submitting a job to the cluster.Executable and Submit file

Grid Submission
The GRID submission part on the ce01-htc is nearly the same as the one used to submit on the old cluster. You can use 2 types of authentication methods:
Token submission
That the steps are identical to those in the HTCondor 9 cluster::
- Register a Client (or upload it of an already submitted)Register a new Client

SSL submission
The SSL Submission substitution of proxy, this process is almost identical.
CAVEAT
To be able to submit jobs using the SSL authentication, your x509 User Proxy FQAN must be mapped in the CE configuration.
You will need to send to the support team via the user-support@lists.cnaf.infn.it mailing list the output of the voms-proxy-info --all --chain corresponding to a valid voms proxy:
