IBM LoadLeveler for AIX 5L: Using and Administering

node_usage

Specifies whether this job step shares nodes with other job steps.

The syntax is:

node_usage = shared | not_shared | slice_not_shared

Where:

shared: Specifies that nodes can be shared with other tasks of other job steps. This is the default.
not_shared: Specifies that nodes are not shared: no other job steps are scheduled on this node.
slice_not_shared: Specifies that a job step will not share nodes with other job steps when it is running in its own time-slice. When the time slice ends, other job steps can run. On nodes where the job step is running, Gang matrix columns can have rows with only this job step specified but not a row with both this job step and another job step specified.

Note:

When SCHEDULER_TYPE is LL_DEFAULT or BACKFILL, slice_not_shared will have the same meaning as not_shared. This allows use of the same job command file with different values of SCHEDULER_TYPE.
