Andes job script stdout/stderr file specifications

[secondspass]

In the Common Batch Options to Slurm section in Andes, we talk about the -o and -e flags. That section seems to imply that if we don't use -o or -e, the output is automatically saved to a file with the filename <job_script>.o$SLURM_JOB_UID. This is actually not the case. By default both standard output and standard error are directed to a file of the name "slurm-%j.out", where the "%j" is replaced with the job allocation number.

Also, we should provide some guidance on using some commonly used filename patterns like %j for the -o and -e files (current documentation doesn't provide that information).
