Maui reservations

Example: create a reservation for 6 cores for jobs submitted to the short queue on working days (Mon-Fri) from 9:30 to 18:30.

Using a standing reservation in Maui, the following fragment should be added to the configuration file /var/spool/maui/maui.cfg, followed by a restart of the maui daemon.

SRCFG[short] STARTTIME=9:30:00 ENDTIME=18:30:00
SRCFG[short] PERIOD=DAY DEPTH=3
SRCFG[short] DAYS=Mon,Tue,Wed,Thu,Fri
SRCFG[short] TASKCOUNT=6 RESOURCES=PROCS:1
SRCFG[short] TIMELIMIT=4:00
SRCFG[short] CLASSLIST=short

Maui creates a reservation:

Using the setres command (e.g. from a cron job), the command is:

# /usr/bin/setres -n short  -r "PROCS=2" -s 09:30:00 -e 18:30:00 -c short 'tbn(08|09|17).nikhef.nl'

And Maui has the following reservation:

# showres short.0
