[Condor-users] Multi-query for completed jobs

["Peter Troeger" <peter.troeger@xxxxxxxxxxxxxxxxxx>]

Hi,

I want to determine programatically (in C) if any job of a number of 
jobs is completed / failed. I have a list of the job names, as well as 
according log files. Currently I see three possibilities for doing this:

1.) Go iteratively through all logfiles and search for the "Finish" 
term. This might be optimized by checking the modification time of the 
files.
2.) Ask iteratively condor_history until it finds at least one job to be 
completed. It is possible to give multiple job ID's to condor_history in 
the query ("-constraint"), but with a large set of jobs I might run into 
a problem with the maximum length of a command line.
3.) Ask iteratively condor_q  and wait until at least one of the jobs is 
removed from the queue.

I experienced some bad performance with condor_history in Condor 
6.7.12., some maybe number 1 is the most appropriate solution ? Any 
other ideas ?

Thank you,
Peter Tröger.
