This error happens when you run remote jobs to another computer from your local machine with Lumerical 2021 R2.

To resolve this we have the following guidelines for running simulations on remote machines.

Windows:

  • Open Resources. 
  • Select Remote: Intel MPI as the Job launching preset
  • Specify a writable location on the remote resource for the APPDATA variable in the Resource advanced options for Intel MPI.
-env APPDATA "\writable\path"

Linux:

Specify a writable location on the remote machine for the HOME variable in the Resource advanced options for the MPI.

-env HOME "/writable_path" 

Running from terminal/command prompt,

mpiexec  -hosts node4:16,node6:16  -env HOME /writable_path ./<path>/fdtd-engine-mpich2nem /<path>/simulationfilename
