MATLAB: Do I receive a “stack size error” when I attempt to start MATLAB 6.5 (R13) using the Load Sharing Facility (LSF) job management software

-xx:threadstacksize=8194javaMATLABnojvmsize;stackthreadthreadstacksize

I submitted a MATLAB job using the following LSF commands:

 bsub -I -q asml_share 'ulimit -Ss 2097148;ulimit -Ss;matlab'

However, I receive the following error message in my terminal window:

 Stack size of 2097152 Kb exceeds current limit of 2097148 Kb.
 (Stack sizes are rounded up to a multiple of the system page size.) See
 limit(1) to increase the stack size limit.

I tried increasing the "ulimit" parameter as suggested in Solution 1-1AOAX, but I am still unable to resolve this issue. I tried forcing the hardlimit to 2097148 and that did not work either.

Note that I am able to start MATLAB via LSF if I use the '-nojvm' switch.

You can resolve the stack size error by using the appropriate LSF commands in conjunction with the attached version of the java.opts file. Here are the required steps to download the java.opts file and submit a MATLAB job via LSF:

1. Download the attached file, java.opts. Place the file in the following directory:

$MATLAB\bin\$ARCH

(where $MATLAB is the MATLAB root directory on your machine, as returned by typing

matlabroot

at the MATLAB command prompt, and $ARCH is the architecture type for your processor.)

2. Start MATLAB as an LSF job, using the following command:

 bsub -Is -q queue_name matlab

MATLAB: How to include a java.opts file in the MATLAB Compiler-generated application

The ability to include a java.opts file is not available in MATLAB Compiler.

To work around this issue, you must manually place java.opts in one of the following locations:

1. <mcr_root>/<ver>/bin/<arch> directory, where <mcr_root> is the location where MATLAB Compiler Runtime (MCR) is installed, <ver> is the corresponding version number of the MCR and <arch> is the system architecture string.

2. The directory that the application is started from

Be aware that putting the file in the bin/win32 directory of the MCR affects every application that runs using that MCR.

MATLAB: Do I receive a Java Exception when starting MATLAB 6.5 (R13) or later

This error is due to the way that the JVM is using memory on your system. There are several solutions to this problem. Platform specific solutions are as follows:

1. Create a java.opts file for the Java VM (for Windows and UNIX):

===========

In the following directory

$MATLAB/bin/$ARCH create a java.opts file. In that file, add a line such as:

 -XX:ThreadStackSize=8192

Where $MATLAB is your root MATLAB directory and $ARCH is your architecture.

For example by default:

$MATLAB

     Windows - C:\MATLAB6p5
     UNIX, Linux - /usr/local/MATLAB6p5
     Mac OS X - /Applications/MATLAB6p5

$ARCH

     alpha, glnx86, hp700, hpux, ibm_rs, mac, sgi, sol2

2. Lower your stack limit (for UNIX only):

===========

MATLAB will work with 16MB stack limit. To lower the limit, issue the following command at the UNIX prompt

limit stacksize 16384

this can be done as part of your login script.

3. Keep your stack limit high, but create an alias or a wrapper script for running MATLAB that lowers the Java stack size to something smaller when starting MATLAB (for UNIX only):

===========

The script should do the same thing as option number 2.

4. Run MATLAB without the Java VM (for Windows and UNIX):

===========

To do this, type the following at the UNIX prompt

matlab -nojvm

NOTE: If you select option number four, you will not have access to the Java features of MATLAB such as the desktop, editor, on any other java enabled feature of MATLAB.
