LSF_STRICT_CHECKING

Syntax

LSF_STRICT_CHECKING=Y

Description

If set, enables more strict checking of communications between LSF daemons and between LSF commands and daemons when LSF is used in an untrusted environment, such as a public network like the Internet.

If you enable this parameter, you must enable it in the entire cluster, as it affects all communications within LSF. If it is used in a MultiCluster environment, it must be enabled in all clusters, or none. Ensure that all binaries and libraries are upgraded to LSF Version 7, including LSF_BINDIR, LSF_SERVERDIR and LSF_LIBDIR directories, if you enable this parameter.

If your site uses any programs that use the LSF base and batch APIs, or LSF MPI (Message Passing Interface), they need to be recompiled using the LSF Version 7 APIs before they can work properly with this option enabled.

Important:

You must shut down the entire cluster before enabling or disabling this parameter.

If LSF_STRICT_CHECKING is defined, and your cluster has slave hosts that are dynamically added, LSF_STRICT_CHECKING must be configured in the local lsf.conf on all slave hosts.

Valid value

Set to Y to enable this feature.

Default

Not defined. LSF is secure in trusted environments.
