RemoteClusters Section
Optional. This section is used only in a MultiCluster environment. By default, the local
cluster can obtain information about all other clusters specified in
lsf.shared. The
RemoteClusters section limits the clusters that the local cluster can obtain information
about.
The RemoteClusters section is required if you want to configure cluster equivalency,
cache interval, daemon authentication across clusters, or if you want to run parallel jobs
across clusters. To maintain compatibility in this case, make sure the list includes all
clusters specified in
lsf.shared, even if you only configure the default behavior for
some of the clusters.
The first line consists of keywords. CLUSTERNAME is mandatory and the other
parameters are optional.
Subsequent lines configure the remote cluster.

CLUSTERNAME
Description
Remote cluster name
Defines the Remote Cluster list. Specify the clusters you want the local cluster will
recognize. Recognized clusters must also be defined in
lsf.shared. Additional
clusters listed in
lsf.shared but not listed here will be ignored by this cluster.
EQUIV
Description
Specify ‘Y’ to make the remote cluster equivalent to the local cluster. Otherwise, specify
‘N’. The master LIM considers all equivalent clusters when servicing requests from
clients for load, host, or placement information.
EQUIV changes the default behavior of LSF commands and utilities and causes them
to automatically return load (
lsload(1)), host (lshosts(1)), or placement
(
lsplace(1)) information about the remote cluster as well as the local cluster, even
when you don’t specify a cluster name.
CACHE_INTERVAL
Description
Specify the load information cache threshold, in seconds. The host information
threshold is twice the value of the load information threshold.
To reduce overhead and avoid updating information from remote clusters unnecessarily,
LSF displays information in the cache, unless the information in the cache is older than
the threshold value.
Default
60 (seconds)
