I spent the weekend trying to get a job to finish on cheyenne because I don't have cron access. I have tried various solutions for repeatedly calling the launch command, such as long command-line sequences with sleep calls, and bash and python scripts that sleep between launch calls, but I seem to get logged off cheyenne after a short time. Even commands I run in the background seem to get terminated. Then my SRW jobs time out due to wtime limits. I'm sure I'm missing something obvious here, but does anyone have any first-hand experience reliably maintaining the workflow on cheyenne without access to cron? I'm looking for best-practice suggestions so that I don't have to keep experimenting.
