[mpich-discuss] installation of MPI2-1.4.1p1 on Win7-PC does not work (SMPD problem?)

Fri Sep 14 10:58:12 CDT 2012

Hi,
 MPICH2 does not (unfortunately) support installing ia32 and x86_64 versions of the software stack on the same system. Uninstall MPICH2 (all versions) installed in your system and follow the steps below.
 Find out whether your OS is 64-bit or 32-bit (Control panel). If your OS is 64-bit install mpich2-1.4.1p1-win-x86-64.msi, if your OS is 32-bit install mpich2-1.4.1p1-win-ia32. Run the example program cpi.exe in "C:\Program Files\MPICH2\examples" (or depending on your install directory) directory to see if MPICH2 works.

Regards,
Jayesh

Subject: [mpich-discuss] installation of MPI2-1.4.1p1 on Win7-PC does not work (SMPD problem?)

Dear developers of MPICH2, 

I tried to install MPICH2 on my Windows7 (64-bit) PC (Intel XEON Quadcore, 16 GB RAM). 

I do not know, which of the 2 packages that can be downloaded for Windows from 

http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads 

is the right one for my PC: 

mpich2-1.4.1p1-win-x86-64.msi 

or: mpich2-1.4.1p1-win-ia32 

First question: which of the 2 packages is the right one? 

So I installed both (logged in as administrator) . But with none of them I am able to run my SPRAYCORE.exe executable. 

I use the following small batch-script runMPICH to start the execution under MPICH:

It got the following answers when running both installations: 

This is the answer when using the installation from mpich2-1.4.1p1-win-x86-64.msi :

Error while connecting to host, Es konnte keine Verbindung hergestellt werden, da der Zielcomputer die Verbindung verweigerte. (10

C:\Windows\System32> 

The host name mentioned in the answers is indeed correct: VT-001016D.intra.dlr.de 

Translation of: Es konnte keine Verbindung hergestellt werden, da der Zielcomputer die Verbindung verweigerte. 

No connection could be established, because the goal-computer refused the connection. 

You see that the answers of the 2 installations differ only by asking the authentification SMPD passphrase (still ‘behappy’) or not. 

It makes no difference, whether I do that as an administrator or as a normal user. 

(By the way: It is cumbersome to be asked at every MPICH run for entering the passphrase!) 

You see, there is a problem with the smpd.exe. The task manager shows that there is no process smpd.exe running on my machine. 

(In contrast, on a WinXP-machine (32-bit) of a collegue that process is running automatically since startup of the computer. And there MPICH works.) 

My 2 nd Question: Can you help me? 

Thank You, 

Michael Rachner
