Batch-Related Command Summary

This section summarizes two groups of batch-related commands: commands that are run on the login nodes to manage your jobs and commands that are run only inside a batch script. Only the most common options are described here.

Many of these commands are discussed in more detail elsewhere in this document. All have online manual pages (example: man sbatch ) unless otherwise noted.

In describing the usage of the commands we use square brackets [like this] to indicate optional arguments. The brackets are not part of the command.

FFTW

FFTW is a C subroutine library for computing the Discrete Fourier Transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data. It is portable and performs well on a wide variety of platforms.

AMBER

The Assisted Model Building with Energy Refinement (AMBER) package, which includes AmberTools, contains many molecular simulation programs targeted at biomolecular systems. A wide variety of modelling techniques are available. It generally scales well on modest numbers of processors, and the GPU enabled CUDA programs are very efficient.

CUDA

CUDA™ (Compute Unified Device Architecture) is a parallel computing platform and programming model developed by Nvidia that enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).

Job Submission

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.

Standard batch job

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:
