[Condor-users] condor_submit wrapper

[Steven Timm <timm@xxxxxxxx>]

I am running condor 6.7.7 and using group quotas on my condor cluster.
Most jobs are submitted to this cluster using the Globus GRAM interface
and I have hacked the condor.pm to add a
+AccountingGroup = "group_<group>.<user>"
to the classad of all incoming jobs from the grid.  This has
been working fine.
(Note that the names of the accounting groups on my system correspond to
the unix group names of the users in the passwd file).

I am now trying to do the same for local jobs.  I've written
the following perl wrapper for condor_submit, which successfully
does submit the job to the local schedd and put it in the correct
accounting group.  It is grabbing the username and groupname
of the user on the fly.


[root@fngp-osg bin]# cat condor_submit_wrap.pl
#!/export/osg/grid/vdt/bin/perl
    my $realusername = (getpwuid($<))[0];
    my $realgroupname = (getgrgid($())[0];
    my $groupstring =  "+AccountingGroup = \"group_$realgroupname.$realusername\"";
    my $systemstring = "/export/osg/grid/condor/bin/condor_submit_real -a '$groupstring' @ARGV ";
    system ($systemstring);


----------------
But when I put this perl wrapper in the place of condor_submit and
rename the condor_submit binary to condor_submit_real, all
sorts of wierd things happen.  So--the first question--
should any such wrapper to condor_submit be returning the
return code of the real condor_submit binary, and if so, how would
this be done.
Second question, is there anything else obvious I'm missing?

Thanks

Steve Timm
