Helium currently offers TecPlot 360 for use on the clusterTecPlot 360 is currently available on the HPC cluster system at the University of Iowa. One may use the Matlab TecPlot environment by loading the appropriate module:
[user@helumuser@hpc:~]$ module load tecplot_2013R1
While it is possible to run TecPlot interactively, which can be especially useful for prototyping a job, please remember that login nodes are a shared resource and are intended for launching jobs or prototyping smaller versions of jobs you intend to run. It It is not advisable to use interactive sessions for long-running, compute-intensive jobs unless one uses a qlogin session to do so.
You can run Tecplot 360 in batch mode to create plots without displaying any graphics to the screen. Note that on our Linux-based cluster, batch TecPlot jobs should be invoked using the "-mesa" option as some OpenGL resources are not available in batch mode.
A guide to scripting for TecPlot is available here: TecPlot 360 Scripting Guide.
Here is a simple example of using Tecplot in batch mode. This example creates an exported JPEG of a cylinder. Use Use "qsub tecplot.sh" to submit to SGE.
