Using and Administering

Designating Machines to Which Jobs Will be Routed

To designate a machine to which your jobs will be routed, follow these steps:

1. Set up a special class in the LoadL_admin file by adding the following class definitions to the file:

   NQS_class =  true  | false

   When this flag is set to true, any job submitted to this class will be routed to an NQS machine.

   NQS_submit = name

   The name of the NQS pipe queue to which the job will be routed. When the job is dispatched by LoadLeveler, LoadLeveler will invoke the qsub command using the name of the this queue.

   NQS_query = queue names

   A blank delimited list of queue names (including host names if necessary) to be used with the qstat command to monitor the job and qdel to cancel the job.

   You can set up multiple classes to access different machines.

2. Modify the local configuration file on the machines that you want to accept this class of jobs.
3. Add the NQS_DIR keyword to the LoadL_config file:

   NQS_DIR = NQS directory

   defines the directory where NQS commands qsub, qstat, and qdel reside. The default is /usr/bin.
