[Condor-users] USER_JOB_WRAPPER environment

[Martin Billinger <martin.billinger@xxxxxxxxx>]

Dear all,

I'm for the first time trying to set up condor (version 7.6, debian  
stable). Currently I have one dedicated machine that acts as Central  
Manager, Execute and Submit host. This is an SMP machine, which was  
configured to provide dynamic slots.

Now I want to enforce resource limits on jobs, so that a job which  
specifies a certain amount of memory requirement cannot exceed that  
memory limit.
I added USER_JOB_WRAPPER = $(LIBEXEC)/condor_limits_wrapper.sh, but  
this does not work as intended.

I added echo `env` > /tmp/test to the script, to write it's  
environment to a file.
For standard universe jobs this is the result:
% cat /tmp/test
CONDOR_SCRATCH_DIR=/var/lib/condor/execute/dir_28693  
_condor_BIND_ALL_INTERFACES=TRUE PWD=/var/lib/condor/execute/dir_28693  
_CONDOR_SLOT=slot1_1 SHLVL=1 _=/usr/bin/env
As you can see, _CONDOR_MACHINE_AD, _CONDOR_JOB_AD, and  
_CONDOR_WRAPPER_ERROR_FILE are not defined.

When submitting the job to the vanilla universe:
% cat /tmp/test
_CONDOR_JOB_PIDS= TMPDIR=/var/lib/condor/execute/dir_29013  
_CONDOR_ANCESTOR_26072=29013:1331399998:1171751342  
_CONDOR_SCRATCH_DIR=/var/lib/condor/execute/dir_29013  
TEMP=/var/lib/condor/execute/dir_29013 PWD=/home/xxxxxxxx/testjob/run  
_CONDOR_WRAPPER_ERROR_FILE=/var/lib/condor/execute/dir_29013/.job_wrapper_failure _CONDOR_SLOT=1 _CONDOR_ANCESTOR_29013=29014:1331399998:109633735 SHLVL=1 _CONDOR_MACHINE_AD=/var/lib/condor/execute/dir_29013/.machine.ad TMP=/var/lib/condor/execute/dir_29013 _CONDOR_ANCESTOR_26068=26072:1331391506:2264895056 _CONDOR_JOB_AD=/var/lib/condor/execute/dir_29013/.job.ad _CONDOR_JOB_IWD=/home/xxxxxxxx/testjob/run  
_=/usr/bin/env
Now the environment variables are defined.


Is this behavior intended? The manual seems to claim this should work  
for both, vanilla and standard universe.

Is there any other way to access ClassAds or enforce resource limits?

Best,
Martin
