[Condor-users] Setting Job Names in Condor?

[Armen Babikyan <armenb@xxxxxxxxxx>]

Hello,

A few months ago, I asked a question about whether or not Condor's DAG 
functionality planned to add a feature about serially-executing several 
processes in a row using DAGs, in an effort to preserve data locality.  
Such a feature would contribute leaps and bounds to the efficiency of a 
condor-ized system that has high I/O throughput (either to shared memory 
buffers, or local diskspace).  I didn't find a viable feature using 
DAGs, so instead I created a simple wrapper-esque utility that runs 
several specified jobs in a row, and provides simple exception handling, 
signal passing, logging and data movement abilities.  I'll look into 
open-sourcing it.

One thing I can't do, however, is display any job-specific information 
in an output of condor_q.  condor_q current shows the name of my 
wrapper-esque program, when I'd really like it to display some other 
useful information, such as a user-specified program state, what 
sub-program is being run, etc.  I'd figure the easiest way to do this 
would be through argv[0], but that is apparently being used by some 
condor internal behavior: 
http://www.cs.wisc.edu/condor/manual/v6.7/2_16Potential_Problems.html

Is there any other available trick to changing these job names in condor 
while they are running?  If not, would the Condor Team consider adding 
this to a list of requested features?  Would anyone else find this useful?

You guys/gals are doing a great job.  Thanks!  =)
