You send input to the Condor system using a submit file, which is a text file of
<attribute> = <value> pairs. The naming convention for a submit file is
<file name>.submit. Before you submit any batch processing, you first set up a directory in which to work, and create the executable script or program that you choose to submit for processing.
Basic attributes used in the submit file include the following:
Universe- At HMDC you specify the
vanillauniverse, which supports serial job processing. HMDC does not support use of other Condor environments.
Executable- Type the name of your program. In the job
ClassAd, this becomes the
Cmdvalue. The default value in the RCE for this attribute is the R program.
Arguments- Include any arguments required as parameters for your program. When your program is executed, the Condor software issues the string assigned to this attribute as a command-line argument. In the RCE, the default arguments for the R program are
Input- Type the name of the file or the base name of multiple files that contain inputs for your executable program.
Output- Type the name of the file or the base name of multiple files in which Condor can place the output from your batch job.
Log- Type the name of the file or the base name of multiple files in which Condor can record information about your job's execution.
Error- Type the name of the file or the base name of multiple files in which Condor can record errors from your job.
Queue- The command
queueinstructs the Condor system to submit one set of program, attributes, and input file for processing. You use this command one time for each input file that you choose to submit.
When you specify file-related attributes (executable, input, output, log, and error), either place those files within the directory from which you execute the Condor submission or include the relative path name of the files. See for more information about using subdirectories.
There are three additional attributes that are required in your submit file when you use batch processing in the RCE. These attributes define when to write an output file, the name of the output file to write at that time, and the number of Condor machines to use when executing your batch process. For each of these attributes, use the following specific values in your submit file:
when_to_transfer_output = ON_EXIT_OR_EVICT
transfer_output_files = <your output file>
