Understanding Resources
Load Indices
Load indices are built-in resources that measure the availability of dynamic,
non-shared resources on hosts in the LSF cluster.
Load indices built into the LIM are updated at fixed time intervals.
External load indices are defined and configured by the LSF administrator, who
writes an external load information manager (
elim) executable. The elim collects
the values of the external load indices and sends these values to the LIM.
Load indices collected by LIM
Status
The status index is a string indicating the current status of the host. This status
applies to the LIM and RES.
The possible values for
status are:

Status Description
ok The host is available to accept remote jobs. The LIM can select the host
for remote execution.
-ok When the status of a host is preceded by a dash (-), it means LIM is
available but RES is not running on that host or is not responding.
busy The host is overloaded (busy) because a load index exceeded a
configured threshold. An asterisk (*) marks the offending index. LIM
will not select the host for interactive jobs.
lockW The host is locked by its run window. Use lshosts to display run
windows.
lockU The host is locked by an LSF administrator or root.
unavail The host is down or the LIM on the host is not running or is not
responding.
unlicensed The host does not have a valid license.
