LSF_DYNAMIC_HOST_TIMEOUT

Description

Enables automatic removal of dynamic hosts from the cluster and specifies the timeout value (minimum 10 minutes). To improve performance in very large clusters, you should disable this feature and remove unwanted hosts from the hostcache file manually.

Specifies the length of time a dynamic host is unavailable before the master host removes it from the cluster. Each time LSF removes a dynamic host, mbatchd automatically reconfigures itself.

Valid value

The timeout value must be greater than or equal to 10 minutes.

Values below 10 minutes are set to the minimum allowed value 10 minutes; values above 100 hours are set to the maximum allowed value 100 hours.

Example

LSF_DYNAMIC_HOST_TIMEOUT=60

A dynamic host is removed from the cluster when it is unavailable for 60 hours.

LSF_DYNAMIC_HOST_TIMEOUT=60m

A dynamic host is removed from the cluster when it is unavailable for 60 minutes.

EGO parameter

EGO_DYNAMIC_HOST_TIMEOUT

Default

Not defined. Unavailable hosts are never removed from the cluster.
