The syntax in SGE to address a particular host is: -l h=$hostname
It's not like ssh where you give just the target. But unless there is a bold
reason, SGE will usually select an appropriate exechost for you. That's the
purpose of a queuing system.

Not when they are inside a variable: "-l" is the option and "vl" the argument
to that option. Having "-l vl" is something SGE doesn't understand as it should
have been broken down. But there is nothing in the TCL performing that.
$ foo="-l h=node29"
$ qsub "$foo" -b y /bin/sleep 5
qsub: ERROR! invalid option argument "-l h=node29"
$ qsub $foo -b y /bin/sleep 5
Your job 277648 ("sleep") has been submitted
And it looks like TCL is forwarding the argument like the content of a variable
is just one option and not option plus argument.
