qsub directive for node name

Hi,

I haven't been able to find anything in the manuals as to whether I can do
this, but is there a directive for qsub that will let me give the node
name that I want to run a job on?  For example I want a job to run on the
node named host05 and another on the node host03 specifically and not
whatever one they normally get dumped to.  Is this possible?

Thanks,
