LSF_LICENSE_MAINTENANCE_INTERVAL

Syntax

LSF_LICENSE_MAINTENANCE_INTERVAL=time_seconds

Description

Specifies how often LSF checks the LSF licences when starting or restarting the cluster. A small number could delay LSF. Valid values are from 5 to 300.

When this parameter is not set, the default value is used.

Recommended value

Set LSF_LICENSE_MAINTENANCE_INTERVAL depending on your cluster size, system buffer size, license server, and cluster communication speed:
  • If you have network delays or a small system buffer (less than 32 KB), set LSF_LICENSE_MAINTENANCE to the high end of the valid values (300).

  • For a small cluster (fewer than 1000 hosts), specify LSF_LICENSE_MAINTENANCE_INTERVAL with 5-60 second value.

  • For a large cluster (greater than 4000 hosts) with limited licenses, use the maximum value: 300 seconds.

  • If you have slow cluster communication (for example, if you use a Web-based intranet), use the maximum value: 300 seconds.

Default

5 seconds
