Using Advance Reservation
Adding a one-time
reservation (-b
and -e)
Use the -b and -e options of brsvadd to specify the begin time and end time
of a one-time advance reservation. One-time reservations are useful for
dedicating hosts to a specific user or group for critical projects.
The day and time are in the form:
[[[year:]month:]day:]hour:minute
with the following ranges:
◆ year: any year after 1900 (YYYY)
◆ month: 1-12 (MM)
◆ day of the month: 1-31 (dd)
◆ hour: 0-23 (hh)
◆ minute: 0-59 (mm)
You must specify at least hour:minute. Year, month, and day are optional.
Three fields are assumed to be day:hour:minute, four fields are assumed to
be month:day:hour:minute, and five fields are
year:month:day:hour:minute.
If you do not specify a day, LSF assumes the current day. If you do not specify
a month, LSF assumes the current month. If you specify a year, you must
specify a month.
You must specify a begin and an end time. The time value for -b must use the
same syntax as the time value for -e. It must be earlier than the time value for
-e, and cannot be earlier than the current time.
Examples ◆ The following command creates a one-time advance reservation for 1024
processors on host hostA for user user1 between 6:00 a.m. and 8:00 a.m.
today:
% brsvadd -n 1024 -m hostA -u user1 -b 6:0 -e 8:0
Reservation "user1#0" is created
The hosts specified by -m can be local to the cluster or hosts leased from
remote clusters.
◆ The following command creates a one-time advance reservation for 1024
processors on a host of any type for user user1 between 6:00 a.m. and
8:00 a.m. today:
% brsvadd -n 1024 -R "type==any" -u user1 -b 6:0 -e 8:0
Reservation "user1#1" is created
◆ The following command creates a one-time advance reservation that
reserves 12 CPUs on hostA between 6:00 p.m. on 01 December 2003 and
6:00 a.m. on 31 January 2004:
% brsvadd -n 12 -m hostA -u user1 -b 2003:12:01:18:00 -e
2004:01:31:06:00
Reservation user1#2 is created
Adding a
recurring
reservation (-t)
Use the -t option of brsvadd to specify a recurring advance reservation. The
-t option specifies a time window for the reservation. Recurring reservations
are useful for scheduling regular system maintenance jobs.
The day and time are in the form:
