Dear all,
I have a problem to run Telemac v7p0 in parallel.

I have installed the Intel compiler 11.1, and the Intel MPI library 5.0 update 2. Compilations for both configurations (sequential, parallel) are OK.
Simulations are running in sequential mode.

However, when I launch a simulation (the "malpasset" case) with the key word "PARALLEL PROCESSORS=4" in the steering file (calcul launched with instruction : "telemac2d.py -c wintelmpi t2d_malpasset-small.cas"), I obtain the message :
"C:\opentelemac\MPICH2\bin\mpiexec.exe" -n 4 C:\opentelemac\v7p0\examples\telemac2d\malpasset\t2d_malpasset-small.cas_2015-02-03-09h31min05s\out_t2d_malpasset-small.exe" and nothing else happens.

I'm obliged to stop manually the run ("Ctrl + c").
All the listing information of this run is given here:

and here nothing else happens

The folder "t2d_malpasset-small.cas_2015-02-03-09h53min01s" created, contains the files given in the attached document "Doc_forum.doc"

This seems to indicate that my problem only comes from my "mpiexec.exe" configuration?
I then tried to launch the command "mpiexec.exe -n 4 out_t2d_malpasset-small.exe" in the folder "t2d_malpasset-small.cas_2015-02-03-09h53min01s". I first had a message asking to give my user name and my password, and after the run performed, but just with one processor (and not 4 as indicated in my steering file and in my command line (mpiexec.exe -n 4).
In the obtained listing file I can identify the following messages :

Would you have any idea of what I can do to run the simulation with several processors?

Thank you very much,

Olivier

sebourban OFFLINE Administrator Principal Scientist Posts: 814 Thank you received: 219	Hello, you may have to register the MPI service -- usually it asks for credentials the first time you use it. Please check on this post: #15663 Hope this helps, Sébastien.

c.coulet OFFLINE Moderator Posts: 3722 Thank you received: 1031	Hi Not sure but instead of giving the number of processors inside the steering file, maybe you could try to specify it at the launch with the --ncsize=4. To be sure, check the T2DCAS in the temp directory, I think you will find a line with PARALLEL PROCESSORS = 1 Hope this helps PS: Think to update your profile!

Hello Sebastien and Christophe,

Thank you very much for your answers.

I had registered to the MPI service. And I launched the simulation with the option --ncsize=xx, this created in the T2DCAS the line : "PROCESSEURS PARALLELES : xx" (just before the line &FIN) but it did not succeed in perfoming the simulation in parallel.
I then tried the commands "smpd -install"; "mpiexec -remove"; " mpiexec -register"; " mpiexec -validate" and " smpd -status" as described above :

---------------------------------------------
-----------------------------------------------------------------------------
C:\Windows\system32>cd C:\opentelemac\MPICH2\examples
C:\opentelemac\MPICH2\examples>smpd -uninstall

Intel(R) MPI Library Process Manager stopped.

C:\opentelemac\MPICH2\examples>smpd -install

C:\opentelemac\MPICH2\examples>mpiexec -remove

C:\opentelemac\MPICH2\examples>mpiexec -register

C:\opentelemac\MPICH2\examples>mpiexec -validate
SUCCESS

C:\opentelemac\MPICH2\examples>smpd -status

--------------------------------------------------------------------------------------------------------------------------

I then tried to run the cpi.exe in C:\opentelemac\MPICH2\examples, I obtained the results above:

-------------------------------------------------------------------------------------------------------------------------------
C:\opentelemac\MPICH2\examples>mpiexec -n 2 -localonly cpi.exe
Enter the number of intervals: (0 quits) Enter the number of intervals: (0 quits
) 4
pi is approximately 3.1468005183939427, Error is 0.0052078648041496
wall clock time = 0.000078
Enter the number of intervals: (0 quits)

-----------------------------------------------------------------------------------------------------------------------

Does this means that my configuration of mpiexec.exe is rather OK?

After that I launch the test simulation of malpasset:

-----------------------------------------------------------------------------------------------------------------------
C:\Windows\system32>cd C:\opentelemac\v7p0\examples\telemac2d\malpasset

C:\opentelemac\v7p0\examples\telemac2d\malpasset>telemac2d.py --ncsize=2 -c wint

-------------------------------------------------------------------------------------------------------------------------------------

I don't understand why I obtain the message : "Aborting: Unable to connect to intranet", whereas it worked with the cpi.exe.
Could it be due to my configuration file : systel.cfg ?(I put it as an attached file) in which I have the option : "mpi_hosts: -mapall" (should I put " mpi_hosts: -localonly"?)

Another surprising point is that when I launch the command : "mpiexec.exe -n 2 out_t2d_malpasset-small.exe" in the temporary folder : " C:\opentelemac\v7p0\examples\telemac2d\malpasset\t2d_malpasset-small.cas_2015-02
-04-13h31min37s", it seems that the run is performed twice, as if mpiexec started 2 processes of same rank 0?

Hi Olivier
It seems your mpi service is well installed and run well (as the example shown)

For the telemac run, you could try to change the configuration to -localonly as it works for cpi.exe, we could think it will work for telemac. I'm not sure about the -mapall option but maybe it could create problems as it should look on the network...

For the other problem, the process was probably launched twice that's why you have a problem with some file access.
What is surprising is the message MPI NCSIZE = 1!

Hope the localonly will solve your problem because I've got no other ideas!

regards

Christophe

Hello Christophe,

Thank you very much for your answer.

I tried to change the configuration to -localonly but without success.

I think I have a problem with mpiexec with Intel. When I launch the example cpi.exe with -n 4, I obtain 4 times the message "Enter the number of intervals: (0 quits) Enter the number of intervals: (0 quits), Enter the number of intervals: (0 quits) ,Enter the number of intervals: (0 quits)"

I don't have this problem with Gfortran, for which I can launch my simulation in parallel without problem .

I will try to use again mpiexec with Intel, and I will tell you,

Regards,

Olivier
