Why is my MATLAB Parallel Server validation and job submission failing with an error regarding a bad interpreter?

1 view (last 30 days)
When validating my MATLAB Parallel Server profile or submitting a sample batch job, I see the following error:
-bash: /var/spool/PBS/mom_priv/jobs/293558.service0.SC: /bin/bash^M: bad interpreter: No such file or directory

When validation occurs, or a job is submitted, the IndependentJobWrapper or the CommunicatingJobWrapper, depending on the job, is copied from the submitting machine to the headnode of the cluster.
If you are submitting from a Windows machine and have previously viewed the IndependentJobWrapper or the CommunicatingJobWrapper in a text base editor, the headnode, which is most likely Linux, will be unable to correctly read the file.
To workaround this issue, you can run dos2unix on the above scripts on the Linux machine and then bring those scripts to the Windows machine.
NOTE: Starting in R2019a the following name changes occurred:
  • MATLAB Distributed Computing Server was renamed to MATLAB Parallel Server
  • mdce_def was renamed to mjs_def
  • mdce binary was renamed to mjs
