Re: [Condor-users] Running multiple jobs on the same computer

["Horvatth Szabolcs" <szabolcs@xxxxxxxxxxxxx>]

Thanks John and Matthias,


I see. So there is no built-in dynamic solution to handle this kind of dependency?
Can I somehow include a text file in a submit file to automatically use its content
as submit information? This way I should only handle the machnie name writing
part and does not have to edit all the other submit files.


Cheers,
Szabolcs
