Condor refers to the iteration number of your batch job as the "Process" number, and the descriptor for your job in aggregate as its "Cluster" number. A Job ID consists of both, separated by a dot: $(Cluster).$(Process)
To track iteration number for batch submissions, use one of the following methods:
- Pass the iteration number as an argument to the executable. For instance, for an R job:
--args '$(Process)'to the Arguments line of your Condor submit file. This passes to the R interpreter the process number of the R run, which progresses from 0 to one less than the number of runs.
- Capture the argument in a variable in your R code by entering the following line:
run <- commandArgs(TRUE). The R object
runcontains the run number. You then can use this object to construct appropriate output file names for your job.
- Inspect the value of the environment variable CONDOR_JOB_JobId. The iteration number of the job will be the portion after the dot.
- Set an environment variable with the value of the Condor-internal variable $(Process), using the
environmentdirective in your submit file as follows:
environment = ITERATION_NUMBER=$(Process)
