Parallel Simulation problems

[santacruz05]

Hey there,

I am have problems using the Pyrosim interface to run parallel FDS simulations. It prompts me for my password, but when I enter it, it says invalid.

I searched the forum and saw that Pyrosim requires an password for MPI access. So I set my password for my administrator account (my only one).

I restarted my computer and tried to run parallel simulation again, and typed in my password when prompted, here is what it says:

Invalid username or password.
Parallel FDS was unable to start processes on this computer.

So I searched more threads and tried to run the simulation in CMD prompt, based on someone elses thread questions... i used the following cmd prompt and got the following error:

C:CEP FilesFire Model testfds>mpiexec -noprompt -port 52200 -priority 1:3 -channel ssm -n 4 fds5_mpi 11.fds

Error while connecting to host, No connection could be made because the target m
achine actively refused it. (10061)
Connect on sock (host=mike-PC, port=52200) failed, exhaused all end points
Unable to connect to ''mike-PC:52200'',
sock error: Error = -1


Help???

Regards,

Mike

There is a remove-register-validate process you can use with MPI passwords that can give us some hints about what is going wrong or maybe even fix the problem.  Have a look at the manual, in the Troubleshooting chapter, MPI Problems section:

If you work through the steps shown under "PyroSim Requires a Password to Run Parallel" and it gives errors of some sort, post a screenshot of your console and we can help debug.
