Hi Jayesh,<br>
<br>
I reconfigured with ch3:sock and I get the same hanging problem.
Testing with cpi:<br>
<br>
../bin/mpiexec -hosts 2 <centos-hostname>
<windows-hostname> -path
"/hactar/src/mpich2-1.3a1/examples;C:\program files
(x86)\mpich2\examples" cpi<br>
User credentials needed to launch processes on deepthought:<br>
account (domain\user): root (yes, the windows username is root)<br>
password: <br>
Process 0 of 2 is on jeltz.mc.vanderbilt.edu<br>
pi is approximately 3.1415926544231318, Error is 0.0000000008333387<br>
wall clock time = 0.000766<br>
<hangs><br>
<br>
Windows firewall is disabled and I get the same results whether the
CentOS box's iptables is on or off.<br>
<br>
Thanks,<br>

<pre wrap="">Hi,
Yes, MPICH2 currently does not support heterogeneous machine configurations (You cannot run your MPI program across 32-bit/64-bit machines/data-models). You should use IA32 version of MPICH2 on the windows 7 machine.
Also make sure that you have configured the unix boxes to use sock (--with-device=ch3:sock) as the channel (the default is nemesis).
Make sure that you don't have firewalls running on any machines.
Let us know the results.
Regards,
Jayesh

Subject: [mpich-discuss] Windows/Linux MPICH2
Hi,
I'm trying to get a cluster working with three types of nodes: 64-bit CentOS 5.4, 64-bit Windows 7, and 32-bit Fedora 8. The 32-bit machines can't run a 64-bit OS so I'm stuck with 32-bit. I'm trying to do this with SMPD but having trouble. Am I correct in thinking that I have to use/compile the 32-bit version of MPICH2 on the 64-bit machines?
It appears that I can't use the Windows node as the typical head node because it needs to map a network drive with different user credentials in order to run. So I'm back to using the CentOS box as a head node. However, when I try to run a job which includes the Windows node, the job hangs.
"smpd -status <windows-hostname>" works as expected from the CentoOS box
"smpd -status <centos-hostname>" works as expected from the Windows box
But trying to run a job and it hangs after outputting "Process #1 (<windows-hostname>) has started."
I've attached the SMPD debug logs for both the CentOS and Windows boxes. I've tried both 1.2.1p1 and 1.3a1 with the same result.
Thanks,
Matt
