When a local cluster requests load or host information from a remote cluster, the information is cached. If the local cluster is required to display the same information again, LSF displays the cached information, unless the cache has expired.
The expiry period for cached information is configurable, so you can view more up-to-date information if you don’t mind connecting to the remote cluster more often.
It is more efficient to get information from a local cluster than from a remote cluster. Caching remote cluster information locally minimizes excessive communication between clusters.
The cache threshold is the maximum time that remote cluster information can remain in the local cache.
There are two cache thresholds, one for load information, and one for host information. The threshold for host information is always double the threshold for load information.
By default, cached load information expires after 60 seconds and cached host information expires after 120 seconds.
