[petsc-users] Using Petsc-Matlab engine on a cluster

[Kaustubh Khedkar]

Hello,
I am using PETSc with Matlab engine. 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 have made sure that I am able to access Matlab using my university details on the cluster (by activating Matlab license through Mathworks.com account). 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.

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?


Thanks,
Kaustubh Khedkar
