Setting Username and Password on MPICH2



When running simulations across multiple Windows computers on a local network network, the resource configuration settings must be updated to use MPICH2, rather than the default MS MPI. With this change, it will be necessary to manually provide your username and password to MPICH2, so it can login to the other machines to start the simulations.

Open the MPICH2 utility:

  • > Start > All Programs > Lumerical > MPICH2 > Set MPICH2 username and password
  • Enter the username and password you will use to login to all of the Windows computers
  • Click on Register
  • Click on OK
