Yes, vManager is mainly intended to run parallel jobs.
You need to open the GUI, click Setup then the Config button.
Next, go to the "DRM" (Distributed Resouce Manager) tab of the Config GUI.
If you're using SunGrid, choose "Generic" (pre-8.1 vManager) or "SGE" for 8.1.
If you're using LSF, choose "LSF".
You have the option to specify the dispatch commands via this GUI, or by using the parameters in the VSIF file:
dispatch_command, pre_session_dispatch_command, post_session_dispatch_command.
If you don't have LSF or SunGrid, but have some other queue system, give us a shout via the forum or a Service Request, and we'll try to work out how to interface with your system.
If you don't have any system setup yet, go ask your IT admin for help, because it's going to take a bit more work! :-)
