Hi.. Can any body give the detailed explanation on the techniques used to balance I/O load in DS parallel jobs?

I'm not sure what your question is without a specific example of a problem you are facing. What is the job design, the number of records, and the time it takes?

One thing you can start with is adding the APT_RECORD_COUNTS environment variable to your job (set it to True), compile, run, and examine the new job log details that the setting adds. This can help you identify the balance of records across partitions.
