I have built an application that uses Matlab engine through PETSc interface. I am trying to run this application on a cluster which has Matlab installed on a network drive (nas drive).

I am also able to run this application using mpirun on the head node (master) which starts the Matlab engine but if I try to run this application using slurm on compute node then the Matlab engine does not start. I have also confirmed that if I login into one of the compute nodes and do a mpirun the Matlab engine does not start there. If I try to launch Matlab on a compute node it asks for Matlab license which the compute node is unable to activate possibly because it is not connected to the internet directly.<o:p class=""></o:p></span></div><div style="margin: 0in; font-size: 12pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 11pt;" class=""><o:p class=""> </o:p></span></div><div style="margin: 0in; font-size: 12pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 11pt;" class="">Is there a way start matlab engine on the head node through Petsc interface even though the application is running on compute nodes or is there any other work around this issue?<o:p class=""></o:p></span></div><div style="margin: 0in; font-size: 12pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 11pt;" class=""><o:p class=""> </o:p></span></div><div style="margin: 0in; font-size: 12pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 11pt;" class=""><o:p class=""> </o:p></span></div><div style="margin: 0in; font-size: 12pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 11pt;" class="">Thanks,<o:p class=""></o:p></span></div><div style="margin: 0in; font-size: 12pt; font-family: Calibri, sans-serif;" class=""><span style="font-size: 11pt;" class="">Kaustubh Khedkar</span></div></div></div></blockquote></div><br class=""></div></body></html>
