Thanks for the second

A couple of quick one-offs on configs:

1) How does a user specify a max runtime on a job from their submit

What do you want to achieve: putting the job on hold if it runs for too long? Or simply specifying the maximum amount of time the job should be
given to finish before being preempted by higher priority jobs?

Here, I'd like to have users be able to specify the max total run time for a parallel job before it's ended.

That way we can have users specify a sanity check on runtime for the time being, until we establish some other policies.

But I would be very interested in the answers to the other cases you pose as well. I assume for the first you want to use a PERIODIC_HOLD expression, but the second would be useful as well.


2) I'm trying to setup a list of "banned" users as such:

   IsBannedUser = ( Owner =?= "baduser") || (Owner =?= "parrott" )

   START =  $(START) && ( IsBannedUser  == FALSE )

however, using this configuration I (user "parrott") can still submit
and run simple jobs (after condor_reconfig -all).

What am I doing wrong here?

If IsBannedUser is not advertised as an attribute in the machine
ClassAd, then you must expand it as a macro when referring to it from
other places in the config file.  Example:

START =  ($(START)) && ( ($(IsBannedUser))  == FALSE )

Note how I have been careful to put ()'s around both macro substitutions
to avoid mistakes in order of operations.

If you do want IsBannedUser to be advertised as an attirbute of the
machine ClassAd, then you can do the following:


Then you can refer to it as you did above, but I would still recommend
putting ()'s around $(START).
