How do I run stat/math jobs, including SAS and SPSS, under AIX LoadLeveler?

To run batch jobs under the IBM AIX LoadLeveler at Indiana University, create a script file on your Libra account. Sample script files are stored in /N/u/statmath/Libra/scripts for you to copy or view. To view the directory from any Libra node, enter:

Note: UITS will retire Libra in spring 2009. Accounts are available on Quarry, a general-purpose Unix computing environment. For more, see About the Libra retirement.

The sample script files in this directory are named with the extension .script. The first part of the filename is the name of the software for which the script is written (e.g., sas.script, spss.script, matlab.script, imsl.script). You can display the sample script file on your screen by entering, for example:

To copy the file to your directory, enter:

Replace filename with the name of the file you want to copy (e.g., sas.script, spss.script). Make sure to keep the . (period) at the end of the command.

When the files are copied to your directory, follow the directions contained in each script file.

Once the script file has been customized, submit the job to the LoadLeveler batch queuing system using the llsubmit command:

Replace scriptname with the name of your script.

Refer to High Performance Systems at IU and Stat/Math Center to check the stat/math software available on Libra and the nodes from which it is available.

To optimize job throughput and minimize paging on Libra, you need to submit all CPU-intensive jobs (i.e., jobs requiring more than 20 minutes of CPU time) as batch jobs. Interactive jobs taking more than 20 minutes of CPU time will be terminated by the system administrator. The IBM AIX LoadLeveler is a load-balancing utility that sets up job queues and dispatches jobs to the least busy node within the Libra cluster.

For more information about statistical and mathematical software, email the UITS Stat/Math Center, visit the center's web page, or phone 812-855-4724 (IUB) or 317-278-4740 (IUPUI). The center is located in Bloomington at 410 N. Park Avenue, and is open for consultation by appointment Monday-Friday 9am-5pm.
