[Condor-users] condor-administrators

[Maxim Kovgan <maxim.kvg@xxxxxxxxx>]

Hello, dear * !

We have a condor pool. 
2 'central managers' oredered with a HAD ( master, collector,
negotiator, had )
2 submission machines (master,schedd only) 
about 200 nodes ( master,startd only )
the collectors are running 6.7.13.
1/2 nodes are 6.7.8 and another half - 6.7.13

We have 2 submission machines for one reason: we want to share this pool
via globus. The globus users will be mapped to local special users, and
will submit ONLY via one specific schedd, local normal user will submit
via another schedd only, the separation is done via unix group
separation and restriction at login level.

The pool overall works quite fine.


2 main problems:

1. custom configuration variables... how ?!
I would want to have a convenient and fault tolerant way to define a
special variable in ${HOSTNAME}.local file to designate the machine has
all globus software installed. e.g. I'd call it IS_LCG2_WN and define it
as True.
I'd write:
IS_LCG2_WN = True
in the config file.

on the schedd I'd add to the jobs' requirement:
APPEND_REQUIREMENTS = ( IS_LCG2_WN =?= True )
or maybe:
APPEND_REQUIREMENTS = ( $(IS_LCG2_WN) =?= True )
or
APPEND_REQUIREMENTS = ( IS_LCG2_WN )


and then the users of globus would have their jobs submitted only to the
chosen machines.

Same would be nice with the execution machines' sides: on schedd I'd
write:

IS_LCG_SUBMISSION = True

and on the startd's side I'd put something like 
RANK = 1 + 10 * IS_LCG_SUBMISSION

etc.

I of course tried all above options, and NONE worked.
I did try to see what condor_config_val has to say about all of these,
and condor_config_val always said that everything is OK, sir.
yep, sure.

I currently add FULL hostnames list in the append_requirements variable.
But this is UGLY. 
Is there another way ?


2. User Environment.
I wonder if there is a way to force users to have a special Environment,
inspite the user's will to define "Env = bla=blabla; etc." in the
submission file.
Is this possible at all ?
According to the manual - no.
(STARTER_* variables can be overridden by users in  the submit file )

Note, I have read the related parts from the manual, but experiments
showed something is wrong.

Please suggest something :)

Best regards,

Max.
