[HTCondor-users] Help

[<aravind.saligram@xxxxxx>]

Hello All !

I am trying to use HTCondor on my local windows CPU for running multiple instances of MATLAB for my simulations.

 

However, HTCondor Job Fails with MATLAB License Error (-39) Despite Valid Installation.

 

I'm submitting a MATLAB batch job using HTCondor with the following submit file:

 

universe = vanilla

executable = run_matlab.bat

arguments = script

transfer_input_files = script.m

output = job_output.txt

error = job_error.txt

log = job_log.txt

should_transfer_files = YES

when_to_transfer_output = ON_EXIT

transfer_output_files = result.mat, matlab_log.txt, runtime_dir_list.txt, bat_debug.txt, dummy_from_bat.txt

queue

 

The batch script run_matlab.bat looks like this:

 

@echo off

echo BAT script started > bat_debug.txt

echo Current directory: %CD% >> bat_debug.txt

 

set MATLABEXE="C:\Program Files\MATLAB\R2024b\bin\matlab.exe"

 

set TMP=%CD%

set TEMP=%CD%

set USERPROFILE=%CD%

set MATLAB_PREFDIR=%CD%\MyDocuments\MATLAB

 

mkdir MyDocuments

mkdir MyDocuments\MATLAB

 

echo Hello from Condor > dummy_from_bat.txt

echo About to run MATLAB >> bat_debug.txt

 

call "C:\Program Files\MATLAB\R2024b\bin\matlab.exe" -batch "run(fullfile(pwd, 'script.m'))"

 

echo MATLAB command finished >> bat_debug.txt

echo BAT script ended >> bat_debug.txt

 

However, when the job runs, MATLAB fails with the following license error:

 

License checkout failed.

License Manager Error -39

Your system administrator has not authorized you to use MATLAB.

Licensing error: -39,147.

 

MATLAB does launch and run the batch file (confirmed in the log), but can't check out a license. This suggests the job environment is not authorized for MATLAB, even though it works fine outside Condor on the same machine.

What I've tried:

• Confirmed that MATLAB works when run manually
• Tried setting environment variables like USERPROFILE, TMP, MATLAB_PREFDIR.
• Verified that bat_debug.txt and other files are created, so the batch script runs as expected.

Questions:

1. How can I make sure the HTCondor job has access to the MATLAB license?
2. Is there a recommended way to forward or configure the license environment in HTCondor?
3. Could HTCondor's user sandboxing (running jobs under a local user) be causing this?

Thanks in advance for any help or suggestions!
