# This select Parallel Environment "mpi" with 4 nodes ![]() There are many ways to invoke this and many options that you can pass, but here’s a simple example using Lumerical ompi test.įirst, the job script fdtd-mpi-example.sh is this: # This "cwd" line will make sure to run from inside the current directory Now, we can run any MPI program we choose on any queue that has the “mpi” parallel environment configured, and Grid Engine will dynamically allocate hosts to the PE. If you are using lumerical device instead of lumerical fdtd, you will also have to load the lumerical/device module. OR you can use modules, like so: module use -s /ad/eng/etc/modulefiles (That’s covered here, but the link has the basic setup, before Lumerical.)įirst, ssh to the SCC and then run: export PATH=/ad/eng/bin:/ad/eng/bin/64/:$PATH You must be set up to run MPI jobs with OpenMPI.Note the publicly accessible MPI cluster on the ENG-Grid was retired in 2018. ![]()
