HTCondor's parallel universe works a little differently than all other HTCondor universes with respect to accounting. Because it may take several negotiation cycles for the parallel universe to accumulate enough machines to run even one job, the machines are claimed not on behalf of the user who will run the job, but on behalf of the scheduler itself, named the DedicatedScheduler. You can see this by looking at the "RemoteOwner" attribute in the startd ad, which will look something like "DedicatedScheduler@submit-machine-name". The usage is then charged to this (non) user until the job starts, after which time, the usage is charged user who started the job.

This usage is the number of wall-hours, not cpu-hours. In you direct measurements, are you shows cpu-time or wall time?
