LSF Version 7.3 - Platform LSF Configuration Reference

Description
Specifies a cluster-wide threshold for exited jobs. If EXIT_RATE is not specified for the host
in lsb.hosts, GLOBAL_EXIT_RATE defines a default exit rate for all hosts in the cluster.
Host-level EXIT_RATE overrides the GLOBAL_EXIT_RATE value.
If the global job exit rate is exceeded for 5 minutes or the period specified by
JOB_EXIT_RATE_DURATION, LSF invokes LSF_SERVERDIR/eadmin to trigger a host
exception.
Example
GLOBAL_EXIT_RATE=10 defines a job exit rate of 10 jobs for all hosts.
Default
Not defined
HIST_HOURS
Syntax
HIST_HOURS=hours
Description
Used only with fairshare scheduling. Determines a rate of decay for cumulative CPU time and
historical run time.
To calculate dynamic user priority, LSF scales the actual CPU time using a decay factor, so
that 1 hour of recently-used time is equivalent to 0.1 hours after the specified number of hours
has elapsed.
To calculate dynamic user priority with historical run time, LSF scales the accumulated run
time of finished jobs using the same decay factor, so that 1 hour of recently-used time is
equivalent to 0.1 hours after the specified number of hours has elapsed.
When HIST_HOURS=0, CPU time accumulated by running jobs is not decayed.
Default
5
JOB_ACCEPT_INTERVAL
Syntax
JOB_ACCEPT_INTERVAL=integer
Description
The number you specify is multiplied by the value of lsb.params MBD_SLEEP_TIME (60
seconds by default). The result of the calculation is the number of seconds to wait after
dispatching a job to a host, before dispatching a second job to the same host.
If 0 (zero), a host may accept more than one job. By default, there is no limit to the total number
of jobs that can run on a host, so if this parameter is set to 0, a very large number of jobs might
