[mpich-discuss] cannot run mpich on multiple hosts due to authentication issues

[Jordan Atlas]

Hello MPICH list,

I am having an issue similar to that described at 
https://lists.mcs.anl.gov/mailman/htdig/mpich-discuss/2006-March/001207.html 
, but I don't see any responses to this inquiry.

I am using MPICH 1.2.5 on Windows XP.

I can run the cpi.exe example for multiple processes on my host machine 
(e.g. mpirun -np 4 cpi.exe).

I am trying to use 2 machines using the command:

C:\Temp>mpirun -np 4 -logon -machinefile machines.txt cpi.exe

When I do this, I get the output:

Mpd needs an account to launch processes with:
account (domain\user): Jordan
password:

easy_connect(jca33-305-desktop-2)

failed because connected host has failed to respond.

Error 10035, process 2:

If I do it without the -logon option I get the same results (without the 
prompt for username and password).

I don't have access to a domain account, but both machines have the user 
'Jordan' with the same password.  Also, both machine names are in the 
machines.txt file.

Does anyone have any suggestions?

Thanks,
