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.
You can specify multiple time windows, but they cannot overlap. For example:
timeWindow(8:00-14:00 18:00-22:00)
is correct, but
timeWindow(8:00-14:00 11:00-15:00)
is not valid.
To configure a time window that is always open, use the timeWindow keyword with
empty parentheses.
Examples GOALS=[THROUGHPUT 2 timeWindow ()]
GOALS=[THROUGHPUT 10 timeWindow (8:30-16:30)]
GOALS=[VELOCITY 5 timeWindow ()]
GOALS=[DEADLINE timeWindow (16:30-8:30)]\
[VELOCITY 10 timeWindow (8:30-16:30)]
NAME
Syntax
NAME=
string
Description
Required. A unique name that identifies the service class.
Specify any ASCII string 60 characters or less. You can use letters, digits, underscores (_)
or dashes (-). You cannot use blank spaces.
IMPORTANT
The name you use cannot be the same as an existing host partition or user
group name.
Example NAME=Tofino
Default
None. You must provide a unique name for the service class.
PRIORITY
Syntax
PRIORITY=
integer
Description
Required. The service class priority. A higher value indicates a higher priority, relative
to other service classes. Similar to queue priority, service classes access the cluster
resources in priority order.
LSF schedules jobs from one service class at a time, starting with the highest-priority
service class. If multiple service classes have the same priority, LSF runs all the jobs from
these service classes in first-come, first-served order.
Service class priority in LSF is completely independent of the UNIX scheduler’s priority
system for time-sharing processes. In LSF, the NICE parameter is used to set the UNIX
time-sharing priority for batch jobs.
Default
1 (lowest possible priority)
