Advance Reservation
[day:]hour[:minute]
with the following ranges:
◆ day of the week: 0-6
◆ hour: 0-23
◆ minute: 0-59
Specify a time window one of the following ways:
◆ hour-hour
◆ hour:minute-hour:minute
◆ day:hour:minute-day:hour:minute
You must specify at least the hour. Day of the week and minute are optional.
Both the start time and end time values must use the same syntax. If you do
not specify a minute, LSF assumes the first minute of the hour (:00). If you do
not specify a day, LSF assumes every day of the week. If you do specify the
day, you must also specify the minute.
When the job starts running, the run limit of the reservation is set to the
minimum of the job run limit (if specified), the queue run limit (if specified),
or the duration of the reservation time window. LSF administrators can prevent
running jobs from being killed when the reservation expires by changing the
termination time of the job using the reservation (bmod -t) before the
reservation window closes.
Examples ◆ The following command creates an advance reservation for 1024
processors on two hosts hostA and hostB for user group groupA every
Wednesday from 12:00 midnight to 3:00 a.m.:
% brsvadd -n 2048 -m "hostA hostB" -g groupA -t "3:0:0-
3:3:0"
Reservation "groupA#0" is created
◆ The following command creates an advance reservation for 1024
processors on hostA for user user2 every weekday from 12:00 noon to
2:00 p.m.:
% brsvadd -n 1024 -m "hostA" -u user2 -t "12:0-14:0"
Reservation "user2#0" is created
◆ The following command creates a system reservation on hostA every
Friday from 6:00 p.m. to 8:00 p.m.:
% brsvadd -n 1024 -m hostA -s -t "5:18:0-5:20:0"
Reservation "system#0" is created
While the system reservation is active, no other jobs can use the reserved
hosts, and LSF does not dispatch jobs to the specified hosts.
◆ The following command creates an advance reservation for 1024
processors on hosts hostA and hostB with more that 50 MB of swap space
for user user2 every weekday from 12:00 noon to 2:00 p.m.:
% brsvadd -n 1024 -R "swp > 50" -m "hostA hostB" -u user2 -t "12:0-14:0"
