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

[Jayesh Krishna]

Hi,
 Good to know your problem is solved.
 
(PS: As you mentioned in your email, pypar might not work with MPICH2 off
the shelf. However it looks like an MPI app and should ideally work with
MPICH2. I would strongly recommend using MPICH2 if possible - MPICH is
old)
 
Regards,
Jayesh

Hi Jayesh,

    Unfortunately I am using a python package (pypar) that requires MPICH
(my understanding is that it's incompatible with MPICH2).  So I'm trying
to get MPICH working in order to later use pypar (note that pypar and
mpich work fine on one machine).

    However, disabling the windows firewall on each machine seems to have
fixed the problem!

Thank you for your help,

--Jordan

 Hi,
  MPICH 1.2.5 is very old. Try using the latest stable version (1.2) of
MPICH2 (available at
http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=down
loads) and let us know if you still have problems.
  Also make sure that you have upgraded WinXP to the latest service pack
(SP3).

(PS: Make sure that you have turned off the windows firewall on your
machines - or look at the windows developer's guide for details on how to
configure MPICH2 with the windows firewall.)

Regards,
Jayesh

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.ht
ml
, 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::WSAETIMEDOUT error, re-attempting
easy_connect(jca33-305-desktop-2)

not properly respond after a period of time, or established connection
failed because connected host has failed to respond.

aborting...
Error 10035, process 2:
   SendInitDataToRoot: recv ack failed
   A non-blocking socket operation could not be completed immediately.


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,

--Jordan Atlas
