Hi, Thanks, Joe. I am not meaning to "ban" anything immediately, I am just curious how often this happen to the HPC community. Perl/shell is really strong tool, one example is to use loop to submit huge mount of jobs and puts burden on scheduler server, the other example is to have one job sit idle and frequently to use system call to detect the job status and resubmit jobs again and again; the other example is that use system call and ssh to each node and run stuff and bypass the scheduler... It just drives me crazy sometime.
How do you guys handle issue like this?

The result of bans of deeply embedded practices usually results in some ... exciting ... meetings, emails, and telephone calls. That said, we use, and our products quite a bit of Perl to submit jobs, and it works fine. If you are running into particular issues, why not discuss them here, and likely you will get lots of good answers back.
