How can we run simulations using distributed computing on Linux systems?
Distributed computing details can be found:
Using the latest version of FDTD and MODE solutions, we can run a simulations using distributed computing from the Terminal window only. This is not possible using the CAD/GUI of the software.
We can use the command to test the MPI functionality. Taking note to use the IP Address of the computers instead of the HostName.
/opt/lumerical/mode/mpich2/nemesis/bin/mpiexec -hosts <node1_IP>:4,<node2_IP>:4 /opt/lumerical/mode/mpitest/cpi-mpich2nem
For information on MPI test program CPi can be found here:
To run a simulation job distributed to 2 computers we can use the command:
/opt/lumerical/fdtd/mpich2/nemesis/bin/mpiexec -hosts <node1_IP>:4,<node2_IP>:4 /opt/lumerical/fdtd/bin/fdtd-engine-mpich2nem -t 1 -logall /<file_location>/<filename.fsp>
