View figure.Users can submit NQS scripts to LoadLeveler and have them routed to a machine outside of the LoadLeveler cluster that runs NQS. LoadLeveler supports COSMIC NQS version 2.0 and other versions of NQS that support the same commands and options and produce similar output for those commands.
The following diagram illustrates a typical environment that allows users to have their jobs routed to machines outside of LoadLeveler for processing:
Figure 31. Environment illustrating jobs being routed to NQS machines.

As the diagram illustrates, machines A, B, and C, are members of the LoadLeveler cluster. Machine A has the central manager running on it and machine B has both LoadLeveler and NQS running on it. Machine C is a third member of the cluster. Machine D is outside of the cluster and is running NQS.
When a user submits a job to LoadLeveler, machine A, that runs the central manager, schedules the job to machine B. LoadLeveler running on machine B routes the job to machine D using NQS. Keep this diagram in mind as you continue to read this chapter.
