This is auto generated.

All jobs in condor exist as a 'process' within a 'cluster' *, the
cluster is basically per submission (technically a cluster shares a
single executable) where as a job is per 'queue' statement in the
submission.

Since you are doing a simple submit you have a cluster with one process
There are a variety of performance benefits to using clusters when the
number of processes within the cluster increases.
If you run condor_q after submitting you will see a list of all the
jobs on that schedd. they will be identified by a composite number
such as 8.0.
This is ClusterId.ProcessId. If you wish to efficiently refer to a
particular job when talking to the queue (perhaps to hold it or
release it) you refer to it either as '8.0' or to refer to the cluster
as a whole just '8'

This identifier is not unique to the pool as a whole, just the schedd
(and it may be reused if you ever wipe the job queue for example).

* These are not the process and cluster names you would expect.
Process just means a single condor job. Cluster is simply a collection
of them.
