Yes. I able registered on both machine. But when I tried to just launch simply command I got error message as stated below: 



C:\>mpiexec -hosts 2 WIN7-PC 1 user-PC 1 "c:\program files\fds\fds5\bin\fds5_mpi 
_win_64.exe" 
abort: Unable to connect to user-PC 


For your information, I have turned off both Window firewall. But still failed to launch any job.

Hi, 
Is the username/password valid on the second machine (Do you have the same Windows username/password on the second machine ? )? If so, you should be able to run your job. Are you able to run your job now ? 
Registration of username/password is local to the machine. MPICH2 does not automatically register the same username on all the nodes. If you would like to register username/password on each machine you should register the credentials on each (Type "mpiexec -register" on each). However, to launch your job you need to have the username/password registered only on the machine/node where you launch your job. 

Let us know the results.

Hi, 

Thanks for the reply. I was able to registered 2 username on 1 of my computer, but I got error message on my 2nd computer when I try to validate user on it. 

Here is the error message. 
FAIL: Unable to read the credentials from the registry. 

Thanks,

>From the error message it looks like you haven't registered a valid username/password with mpiexec. Please register a valid Windows username/password with mpiexec using the "-register" option (Type "mpiexec -register" at the command prompt and mpiexec will prompt you for the username/password). Once the registration is complete validate it using the "-validate" option (Type "mpiexec -validate" at the command prompt). If you have registered a valid Windows username/password the validate option should return SUCCESS. 
Let us know the results.

Hi Jayesh, 


I am trying to running parallel FDS (Fire Dynamic Simulator) via 2 PC by using a config file 


here is my config file 

exe "C:\Program Files\FDS\FDS5\bin\fds5_mpi_win_64.exe" "ParadigmV4-13.fds" 
wdir "\\USER-PC\Project\Paradigm\" 
hosts 
user-PC 6 
WIN7-PC 6 


This is the error message I got from the command prompt. 

C:\>mpiexec -file config.txt 
Credentials for USER-PC\WIN 7 rejected connecting to user-PC 
Aborting: Unable to connect to user-PC 


I used a cross over cable to connect both PCs and I think my setting for the IP address is correct as I can ping each other computer in the command prompt. 
I tried to turned off both firewall but it failed. 
Thanks, 


Regards, 
Koh
