Instruct MPI to authenticate using an alternate account.
To instruct MPI to authenticate using an alternate account (e.g. set to mpi_user on a computer named
aurora), you must issue a command using the console.

To verify that MPI will function with the account information:
C:\Program Files\PyroSim 2013\fds>mpiexec -validate -port 52700
SUCCESS
When trying to Run Parallel, PyroSim Repeatedly Requests a Password
PyroSim attempts to validate the MPI configuration prior to running the simulation. If this validation fails,
PyroSim assumes it was because of a password mismatch. If you know this is not the case (e.g. you know
you entered your password correctly), PyroSim may be responding incorrectly to a different error. To
diagnose this error, please run PyroSim in safe mode. The error output should appear at the bottom of
the console window. Forward this text to <[email protected]> and the support staff
will help resolve the problem.
When Trying to Run Parallel, FDS Completes Immediately with No Output
This indicates that MPI started successfully, but the FDS executable (fds5_mpi) failed to run. To gather
additional information about this error, you must run the MPI executable manually from the command
prompt and observe the error output. To run the MPI executable manually, open a console window and
issue the following commands:
