You will face 3 problems when you install and run Matlab R2008b on Rocks cluster 5.2 (beta). Actually, these issues are not necessary caused by Rocks 5.2 cluster, but, it happened on Rocks on Linux x86_64. So, let's fix them!1. Installation
It happens when you type 'install' after inserting Matlab DVD into your head node.
bash: /media/MATHWORKS_R2008B/install: /bin/sh: bad interpreter: Permission denied
Solution
The reason is that 'noexec' option is applied internally when it is mounted automatically. Simple fix is that just unmount DVD and mount it again "manually". Then, 'noexec' won't be used by default.
$unmount /cdrom
$mount -t iso9660 /dev/cdrom /cdrom

2. Running demo
After installing, you might want to test run demos provided with Matlab. And you would click 'Help/Demo' menu and eventually, will click 'Run this demo' link. But, what you get is not a fancy demo window, but a just frustrating error like this.
Solution
Matlab is not really smart enough to know that you are using Firefox. So we need to let Matlab know that we are using Firefox. How?
Edit this file;
MATLAB_INSTALL_DIR/toolbox/local/docopt.m
In line 52, change this line
doccmd = '';
to
doccmd = 'mozilla';

3. Printing
When you click print within Matlab, you would get this error on Linux;
Caused by: java.lang.NullPointerException: null attribute
at sun.print.IPPPrintService.isAttributeValueSupported(IPPPrintService.java:1147)
at sun.print.ServiceDialog$OrientationPanel.updateInfo(ServiceDialog.java:2121)

at sun.print.RasterPrinterJob.printDialog(RasterPrinterJob.java:855)
at sun.print.PSPrinterJob.printDialog(PSPrinterJob.java:421)
Solution
It is caused by the bugs in Java printing function, which is used by Matlab to print output. There are several workarounds are suggested, but, in my opinion, the easiest and simples way is adding this line;
Option orientation-requested 3
to CUPS's configuration file;
/etc/cups/printers.conf
