Platform LSF Reference Version 6.2

Parameters
Platform LSF Reference
310
The LSF administrator accounts must exist on all hosts in the cluster before installing
LSF
The primary LSF administrator account is typically named
lsfadmin. It owns the LSF
configuration files and log files for job events. It also has permission to reconfigure LSF
and to control batch jobs submitted by other users. It typically does not have authority
to start LSF daemons. Unless an
lsf.sudoers file exists to grant LSF administrators
permission, only root has permission to start LSF daemons.
CAUTION
Yo u sh o ul d not configure the root account as the primary LSF administrator.
Valid Values
User accounts for LSF administrators must exist on all hosts in the cluster before
running
lsfinstall.
Example LSF_ADMINS="lsfadmin user1 user2"
Default
None—required variable
LSF_CLUSTER_NAME
Syntax
LSF_CLUSTER_NAME="
cluster_name"
Description
Defines the name of the cluster.
Valid Values
Any alphanumeric string containing no more than 39 characters. The name cannot
contain white spaces.
Do not use the name of any host, user, or user group as the name of your cluster.
Example LSF_CLUSTER_NAME="cluster1"
Default
None—required variable
LSF_DYNAMIC_HOST_WAIT_TIME
Syntax
LSF_DYNAMIC_HOST_WAIT_TIME=
time_seconds
Description
Defines the period of time from startup for dynamic slave LIMs (hosts) to wait for an
acknowledgement from the master LIM. This signals to the dynamic host that it is
already in the cluster and therefore does not need to be added. If it does not receive this
acknowledgement, the dynamic host sends a request to the master LIM to add it to the
cluster.
To enable dynamically added hosts, you must define both
LSF_DYNAMIC_HOST_WAIT_TIME in lsf.conf, and LSF_HOST_ADDR_RANGE in
lsf.cluster.cluster_name.
Recommended
value
Up to 60 seconds for every 1000 hosts in the cluster, for a maximum of 15 minutes.
Selecting a smaller value will result in a quicker response time for new hosts at the
expense of an increased load on the master LIM.
Example LSF_DYNAMIC_HOST_WAIT_TIME=60
Hosts will wait 60 seconds from startup to receive an acknowledgement from the master
LIM. If it does not receive the acknowledgement within the 60 seconds, it will send a
request for the master LIM to add it to the cluster.
