Time Syntax and Configuration
Variable configuration is used to automatically change LSF configuration based
on time windows. It is supported in the following files:
◆ lsb.hosts
◆ lsb.params
◆ lsb.queues
◆ lsb.users
You define automatic configuration changes in configuration files by using ifelse
constructs and time expressions. After you change the files, reconfigure
the cluster with the badmin reconfig command.
The expressions are evaluated by LSF every 10 minutes based on mbatchd start
time. When an expression evaluates true, LSF dynamically changes the
configuration based on the associated configuration statements.
Reconfiguration is done in real time without restarting mbatchd, providing
continuous system availability.
In the following example, the #if, #else, #endif are not interpreted as
comments by LSF but as if-else constructs.
Begin Host
HOST_NAME r15s r1m pg
host1 3/5 3/5 12/20
#if time(5:16:30-1:8:30 20:00-8:30)
host2 3/5 3/5 12/20
#else
host2 2/3 2/3 10/12
#endif
host3 3/5 3/5 12/20
End Host
Begin Queue
...
#if time(8:30-18:30)
INTERACTIVE = ONLY # interactive only during day shift
#endif
...
End Queue
