[mpich-discuss] MPICH2 & Windows 7

[Jayesh Krishna]

Hi,
 There is no additional step required to get your code running. If you have the windows firewall turned on, try turning it off.
 First try running a non-MPI program using mpiexec,

    mpiexec -n 2 hostname
 
 Now try running a simple MPI hello world program (https://svn.mcs.anl.gov/repos/mpi/mpich2/trunk/examples/hellow.c),

    mpiexec -n 2 hellow.exe

 Let us know if it works.

Regards,
Jayesh

Hi Jayesh,

Thanks for your email. 

I have installed MPICH2 correctly with no error message. 
(i.e. cmd run as administrator -> msiexec /i mpich2-1.2.1-win-x86-64.msi)

Then, I have rebuilt by application code. But when I was trying execute it, either in a cmd window opened as administrator, or not, the program was just hung there (my test program is very simple, it should return within a second).   

The way I started my mpi job was:

mpiexec -n 1 WtDemoRunt1D.exe 

I am wondering if there are extra steps needed to execute my code. What are right steps to launch an MPI job?  

Thanks again,
Liyang

Hi,
 Were you able to install MPICH2 successfully (Did you get any error messages during the install)?
 Typically on Windows 7 you will have to install MPICH2 from an admin command prompt (Right-click on command prompt --> Select "Run as administrator" --> In the command prompt type "msiexec /i mpich2-1.2.1-win-x86-64.msi") or you will have to install SMPD separately(after installing MPICH2) from an admin command prompt (Right-click on command prompt --> Select "Run as administrator" --> In the command prompt type "smpd -install -phrase MYPASSPHRASE").

Regards,
Jayesh

Hi, 



I have installed MPICH2 on a 64-bit Windows 7 machine. I have turned off the firewall, but still I got the following message: 



c:\MZA\wavetrain\trunk\examples\wtdemo>mpiexec -n 1 WtDemoRunt1D.exe 

Error while connecting to host, No connection could be made because the target m 

achine actively refused it. (10061)Connect on sock (host:sandia.mza.lan, port=8676) failed, exhaused all end points 



Unable to connect to 'sandia.mza.lan:8676', 

sock error: Error = -1 



How can I fix that problem? 



Thanks!
