Ciao, Francesca,

Take a look at section 3.12.8 of the 8.4.6 manual. In order for a machine
to match a parallel universe job, it must be advertising the
"DedicatedScheduler" attribute which is set in the configuration and
pushed to the machine ad using the STARTD_ATTRS config.

Once this is set up correctly, you should be good to go. The idea here
is that parallel jobs cannot tolerate having any one of the
parallel processes on any of the machines being terminated unexpectedly,
so machines set up in this way are presumed to prevent eviction and
thus be safe for parallel universe submissions.
