[Condor-users] Marking child as DONE

[Nickolas Fotopoulos <nvf@xxxxxxxxxxxxxxxxxxxx>]

Dear all,

After a DAG has run partway through, I've decided that the bottom-most  
post-processing job (several thousand of them) should/can not be run.   
When my rescue DAG comes, as it inevitably does, I would like not to  
execute these.  So far, no problem; a one-line bash/sed invocation  
takes care of that:

cat $f | sed 's/.*mysubfile.*/& DONE/' > ${f}.sires_done;

The problem is that not all of the parents have completed  
successfully.  I'd like to resubmit the parents, but not these  
children.  When I naively mark them as DONE, as above, I get the  
following error while dagman parses the DAG.

3/13 20:25:13 ERROR: AddParent( ea0bca7d3503cccca43dff66a99c1516 )  
failed for no
de a5bf08f49f3323fdd5f838f6d89918f7: STATUS_DONE      child may not be  
given a n
ew STATUS_READY     parent

Removing the JOB lines produces an error that the parent-child  
relationships refer to a non-existent job.  (I don't have the exact  
message handy.)

I see a few solutions, none of which I like:
* resubmit without modification and let the children fail (wastes  
resources)
* change the submit files to point to /bin/true and run in the local  
universe (a lot of scheduling overhead, I'd think, but maybe this is  
negligible)
* identify all nodes of a class and remove all references to each of  
them (more code than I want to write at the moment)

Can I get some gut reactions to these options or perhaps new, cleverer  
options?

Thanks,
Nick
