OSCER users,
Schooner maintenance is now starting. The maintenance is scheduled until
midnight tonight Oklahoma time.

REMINDER:

Because of Schooner's scheduled maintenance outage this coming
Wed (May 11), if you submit batch jobs to Schooner between now
and then, it might happen that those jobs get delayed until
after the scheduled maintenance outage ends.

You can get such jobs to run before the scheduled maintenance
outage by reducing the amount of wall clock time you request,
specifically the following #SBATCH directive:

#SBATCH --time=DD-HH:MM:SS

OR

#SBATCH -t DD-HH:MM:SS

DD: 2-digit number of days
HH: 2-digit number of hours
MM: 2-digit number of minutes
SS: 2-digit number of seconds

(Or you might use a different time format, like HH:MM:SS
without the number of days and the hyphen.)

For example, if you submit the job at noon today, be sure to
request at most 44 hours (you should probably request 40 hours
or less, to have a margin of error).

We apologize for the inconvenience -- our goal is to make
OSCER systems and services even better!
