Credentials for fire rejected connecting to develop6 (FDS 6.2.2 )

Problems with MPI running

I can’t execute MPI calculation on two connected computers.
When I try to run MPI calculation in Command Prompt I get:

Credentials for fire  rejected connecting todevelop6,　by the way I am using the version6.2.2 and both computers have the password.

Did anyone meet such a problem? 

Best wishes to everyone

I am sorry, the FDS version is 6.2.0, not 6.2.2.

There are several things you need to do to get the MPI working on a Windows domain network. I do not know what you have done. First, read the FDS User's Guide section on MPI under Windows, and the describe what you have done. It might be that your network is not properly configured for MPI.

"Credentials rejected" error occurs when you put in wrong username or password.

Run "mpiexec -remove" to remove currently saved incorrect credentials, then run "mpiexec -register" to put in correct credentials, then run your mpiexec job.

Dear Kevin，Thanks for your kind reply. I will try it and r俄 port the result.

Hi, 

I have the similar issue, credentials rejected. I only need to run FDS locally on one computer, isn´t there any way around the server issue?

Done so far:

• Installed fds 6.7.1
• tried to run it from CMFfds
• used mpiexec -remove and mpiexec -register, nut no compination has been accepted. I only have one account on this computer and I am a bit confused is it the MS-office account I am logging into? This is the one that I am using to log into this computer. I am currently login in with PIN-code, but I also have a password.
• making another account is not made easy on windows, need to have another e-mail address, etc. I am already in trouble with megazillion different accounts and softwares.
• running win 10 pro

Any help is appreciated!

Hi!

if you just want to run FDS locally, there shouldn't be any Problem occuring. I'm working on a PC without admin rights, so i installed the software on another PC, copied the files to my work PC and used the following steps to run FDS locally with MPI or openMP, that doesn't matter. So i wrote a batch File, which is located in the copied directory which looks like the following (it's almost the same like fdsinit.bat which comes with the installation of FDS):

:: base directory / filename
set FDS_base_dir=%~dp0

:: fdsinit.bat (adapted to no-admin edition)
SET I_MPI_ROOT=%FDS_base_dir%\firemodels\fds6\bin\mpi

SET PATH=%I_MPI_ROOT%;%PATH%
:: fdspath.bat (adapted to no-admin edition, ATTENTION: added %PATH% !!!

:: set path containing fds, smokeview, intel mpi and windows entries
SET FDS_PATH=%FDS_base_dir%\firemodels\fds6\bin\
SET SMV_PATH=%FDS_base_dir%\firemodels\SMV6

SET PATH=%SMV_PATH%;%FDS_PATH%;%I_MPI_ROOT%;%WINDIR%;%WINDIR%\system32;%PATH%
::echo PATH=%PATH%

fds_local -p xx -o yy casename.fds

where xx is the number of MPI-processes and yy is the number of openMP processes.

and that is running on every PC

hope this helps for your problem on running FDS locally (i'm using FDS 6.7.1)

best regards

Hi,

Thanks for you reply! Typing "fds filename.fds" I ran into credentials problem I described, but using command "fds_local filename.fds" is working for me!

If I were to make a batch file as you described, how have you named it? What command are you using then to launch FDS then?
