<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 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 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>
easy_connect::WSAETIMEDOUT error, re-attempting<BR>
easy_connect(jca33-305-desktop-2)<BR>
Error: ConnectToMPD(jca33-305-desktop-2:8675): easy_connect failed:<BR>
error 10060, A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.<BR>

MPIRunLaunchProcess: Connect to jca33-305-desktop-2 failed, error 10060<BR>
MPIRunLaunchProcess: Connect to jca33-305-desktop-2 failed, error 10060 aborting...<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>
