A job script is a text file containing job setup information for the batch system followed by commands to be executed. It can be created using any text editor and may be given any name. Some people like to name their scripts something like myscript.job or myscript.sh, but myscript works just as well.
Oakley is an HP-built, Intel® Xeon® processor-based supercomputer, featuring more cores (8,328) on half as many nodes (694) as the center’s former flagship system, the IBM Opteron 1350 Glenn Cluster. The Oakley Cluster can achieve 88 teraflops, tech-speak for performing 88 trillion floating point operations per second, or, with acceleration from 128 NVIDIA® Tesla graphic processing units (GPUs), a total peak performance of just over 154 teraflops.
The Ohio Supercomputer Center's IBM Cluster 1350, named "Glenn", features AMD Opteron multi-core technologies. The system offers a peak performance of more than 54 trillion floating point operations per second and a variety of memory and processor configurations. The current Glenn Phase II components were installed and deployed in 2009, while the earlier phase of Glenn – now decommissioned – had been installed and deployed in 2007.
We currently operate three major systems:
There are two ways to connect to our systems. The traditional way will require you to install some software locally on your machine, including an SSH client, SFTP client, and optionally an X Windows server. The alternative is to use our zero-client web portal, OnDemand.
Job scripts are submitted to the batch system using the sbatch command. Be sure to submit your job on the system you want your job to run on, or use the --cluster=<system> option to specify one.
Most jobs on our system are submitted as scripts with no command-line options. If your script is in a file named myscript:
sbatch myscript
In response to this command you’ll see a line with your job ID:
