Hi Brian,

thanks a lot for the response. TARGET.Machine should work.

I am now realizing that something like this

Requirements = ( other requirements ) && ( User == "my_user" &&
TARGET.Machine ==
"machine.you.want.edu" )

most probably, will prevent any job from a different user to run.
I guess I need to work out the full logic, playing with ANDs and ORs properly.
But that is a different history.

Thanks a lot.
Jose
