The jobs you submit to Opal will be executed using Condor.
Opal simply gives you a web service interface and then it has
different back-end to actually execute your jobs (condor, sge, pbs,
etc.).

you mean the difference between using Opal vs using condor_submit?
If you use Opal you can invoke the lanuchJob operation using
web-service standard (we provide python and java client side
libraries).
If you use condor you have to ssh to a machine (aka have an account)
and then you need to create a submission script and execute
condor_submit.


In NBCR We use Opal to submit job from web portal (where you have 1
user the web portal which is in charge of running different simulation
and opal takes care of creating working directories staging input and
outputs etc.).
