To run jobs interactively you will probably need to use the parallel operating environment (poe) and then specify how many processors and/or nodes you wish to use. For example, to run on 2 processors you could use something like:
poe ./vasp -rmpool 1 -procs 2

The man pages for poe give more detail. Also, you probably will want to check that this is the correct way to run parallel jobs interactively for your system.
