Hi Jayesh,<br>
<br>
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).<br>
<br>
However, disabling the windows firewall on each machine seems to
have fixed the problem!<br>
<br>
Thank you for your help,<br>
<br>

<p><font size="2"> Hi,<br>
MPICH 1.2.5 is very old. Try using the latest stable version (1.2) of
MPICH2 (available at <a moz-do-not-send="true"
href="http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads">http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads</a>)
and let us know if you still have problems.<br>
Also make sure that you have upgraded WinXP to the latest service
pack (SP3).<br>
<br>
(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.)<br>
<br>
Regards,<br>

<br>
Hello MPICH list,<br>
<br>
I am having an issue similar to that described at <a
moz-do-not-send="true"
href="https://lists.mcs.anl.gov/mailman/htdig/mpich-discuss/2006-March/001207.html">https://lists.mcs.anl.gov/mailman/htdig/mpich-discuss/2006-March/001207.html</a><br>
, but I don't see any responses to this inquiry.<br>
<br>
I am using MPICH 1.2.5 on Windows XP.<br>
<br>
I can run the cpi.exe example for multiple processes on my host machine
(e.g. mpirun -np 4 cpi.exe).<br>
<br>
I am trying to use 2 machines using the command:<br>
<br>
C:\Temp>mpirun -np 4 -logon -machinefile machines.txt cpi.exe<br>
<br>
When I do this, I get the output:<br>
<br>
Mpd needs an account to launch processes with:<br>
account (domain\user): Jordan<br>
password:<br>
easy_connect::WSAETIMEDOUT error, re-attempting<br>
easy_connect(jca33-305-desktop-2)<br>

Error 10035, process 2:<br>
SendInitDataToRoot: recv ack failed<br>
A non-blocking socket operation could not be completed immediately.<br>
<br>
<br>
If I do it without the -logon option I get the same results (without
the prompt for username and password).<br>
<br>
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.<br>
<br>
Does anyone have any suggestions?<br>
<br>
Thanks,<br>
<br>
