Octave

What is Octave?

GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to MATLAB so that most programs are easily portable.

Using OCTAVE

To use Octave, please use the following commands or refer to the sample PBS scripts:

System	Command
HPC2015	module load octave/gcc

Sample examples with PBS script for running Octave are available at /share1/octave/sample.

• Running serial OCTAVE jobStep 1: Prepare a “OCTAVE ready” m-file. e.g. test.m

  disp 'Hello World' 

  exit 

  

  Step 2: Prepare a PBS script. Sample pbs script pbs-octave.cmd:

  #!/bin/sh
  #PBS –N test_octave
  #PBS -l walltime=00:10:00

  #PBS -l nodes=1:ppn=1


  #PBS -j oe

  
  octave -q test.m

  # end of example file

  Step 3: Submit the PBS script.

  qsub pbs-octave.cmd
