open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi Tony

Try to first uninstall MPICH2 and check there is no smpd process which runs on your computer.

I checked my notes and found some other informations.
Vcredist_x64.exe and NetFx64.exe are required (install before MPICH2 if necessary)
To install MPICH2, The only solution was to follow this method ...
In menu start / all programs / accessories, right click on command prompt
In the context menu, choose "execute as an administrator" even if you're the administrator of your computer!
In the cmd windows, enter : msiexec /i mpich2-1.3.2p1-win-x86-64.msi (the version could probably be different now)
Follow the instructions (passphrase...) and install for all users.

Check if SMPD process is well create

Hope this helps

Thanks Christophe I will try what you have suggested

excuse my ignorance but where do I get Vcredist_x64.exe and NetFx64.exe (over the net?)

Regards
Tony

yes, you could find those program on the net.
But check before, if you already install MPICH2 those programs should already be install in your computer.
On my computer, I received specific message indicating me those program are missing.

Regards

Thanks for your help but unfortunately all of these tasks have not altered the outcome. But given that its happening on my other Win7 machine suggests that this might be a common occurance with MPICH2 and windows 7.

Hi Tony

If the message remains unable to connect to host, thisis definitively a MPICH2 problem or probably a parameter to adapt

When you run mpiconfig, did you see if your installation in OK (you should see your computer (host) with some informations

Regards

Yes Christophe the mpiconfig shows the name of the computer but indicates an error that MPICH2 is not installed or unable to query the host (I believe it might be the latter?).

regards
Tony

Thanks Fabien and Christophe for pointing me in the right direction


I finally got the MPICH2 to install properly and of course telemac was always correct and runs in parallel mode.


I searched other forums and found that my problem was a common query but often not answered. The following information may be of use to others trying to get windows7 to work with MPICH2.

The error with mpiexec curs if the smpd utility used by MPICH2 has not been installed properly, usually because MPICH2 was not installed when logged in as Administrator (different from user with Administrator privileges). Open an administrator command prompt from Start->All Programs->Accessories->Command Prompt-> Right click run as administrator. Click YES to the user account control about modifying the computer and make sure that the command window that opens says Administrator at the top. You can then enter mpich2-1.4.1p1-win-x86-64.msi (or earlier/ later version) and this will bring you through the instalation putting the MPICH2 files in the directory c:\opentelemac\mpi\ (not the default which places them in C;\program files\MPICH2\.

Verify that c:/opentelemac/mpi/bin is on your path. In this prompt type smpd -install. You should receive confirmation that MPICH2 Process Manager, Argonne National Lab installed.

Then perform the following in administor prompt window:

smpd -install
mpiexec -remove
mpiexec -register (giver user name and password)
mpiexec -validate (it should return SUCCESS)
smpd -status (it should return 'smpd running on <hostname>')

You are now ready to compile telemac and run in parallel

very good Tony -- very happy to see this is all sorted out ! .. and thank you for the solution ...

and, most importantly welcome in the parallel universe of TELEMAC !

Sébastien.

Thanks Sébastien I have finally made it to the parallel side and its upwards and onwards from here.

The workshop and user conference was excellent and congrats to all involved.

Glad to see you are still working late at night.

Regards
Tony
