open TELEMAC-MASCARET The mathematically superior suite of solvers

Bonjour,
J'ai un problème qui est le suivant, lorsque que j’exécute makepar90 j'ai plusieurs erreurs de la forme :


========== telemac3d/tel3d_v6p1/sources :

Pourtant j'ai à priori fait les démarches necessaires:

LK_LIB_SPECIAL="/home/istil/promo09-12/orizono/opentelemac/v6p1/metis-4.0.3/libmetis.a"

ajout dans makefile du répertoire parallel des lignes:
INCMPI = /usr/local/mpich1.2.6/include/mpi.h
LKLIB = /home/istil/promo09-12/orizono/opentelemac/v6p1/metis-4.0.3/libmetis.a

Pourriez vous m'aider svp?

Bonjour,
j'ai oublié d'insérer également le fichier systel.ini au cas où. Merci

Hi
Telemac use MPI2 functions and it seems you try to link with MPI1

Hope this helps

Hello,
Christophe is right, you should use MPI2.
However, you're having another issue (mpi_allreduce & exit belong to both MPI1&2).

You added some targets (INCMPI, LK_LIB...) used by the parallel makefile directly in your config file. As the config file is parsed by Perl scripts, you cannot define here new targets (whithout modifying them).

So, please check your MPI install.
-> You should add ...mpich/bin to your PATH
-> You should add ...mpich/lib to your LD_LIBRARY_PATH
-> mpif.h can be included through FC_OPT_INCLUDE (please see my new post on a similar topic)

... Or re-install MPI in <home_telemac>/mpi

Last but not least, I don t think that the parallel makefile is using the LK_LIB_SPECIAL target. Libmetis is expected in the parallel DIRLIB (intel_64_10 for instance, cf. Install note)

Fabien Decung

One more thing, I already been adressed this issue in the FAQ (dedicated to the some common environment issues):

==> www.opentelemac.org/index.php?option=com...16&Itemid=20&lang=fr)

What?
Message error is :

“… parallelv6p0.a(p_dmax.o): In function `p_dmax_':

p_dmax.f:(.text+0x37): undefined reference to `mpi_allreduce_'

This error message is printed for every function inside parallelv6p0.a

Why?

This happens usually when a fortran compiler instead of the MPI's "wrapper" compiler (mpif90, mpiifort…) is used in FC_MPI in the systel.ini file. It is also not sufficient to define LIBS_MPI with –lmpich or –lmpi.

Solution :

It is strongly recommend to use MPI's "wrapper" compiler to in FC_MPI.

Depending on your MPI library, you may try :

FC_MPI=mpif90 (or mpiifort sometimes)

You should also be careful to the LIBS_MPI variable in systel.ini file.

Tip with OPENMPI (www.open-mpi.org/faq/?category=mpi-apps#cant-use-wrappers)

> mpif90 –showme:link add results in LIBS_MPI

Tip with MPICH2 :

> mpif90 –show add linking options in LIBS_MPI

Thanks, I just added "LIBS_MPI="-L /usr/local/mpich1.2.6/lib -lmpich -lmpi -lpthread -lstdc++ -lz " and now I have only one problem because i link with MPI1 ( problem with function mpi_extent_type" as Christophe said but when i try to compile an exemple I haven't any errors can I keep my config ??
When I run an exemple ,it finished by:

Well, compiling the PARALLEL library is only mandatory for parallel computing. In sequential, TELEMAC uses a void version named PARAVOID. The sequential version seems fine according to your case.

However, parallelism in TELEMAC is such a powerful feature that it's worth it to spend some time in installing MPI2 on your system. When using a recent Linux distribution, MPI2 is often packaged and available through the software center ("logitheque" in french).

Fabien Decung

thanks for your help ^^. But, I have an other problem when i use the parallelism, it's can't find the file mpi_telemac.conf in order to run.. I'm already search this file but i don't find it.. can I create a new file nammed mpi_telemac.conf and config it to run parralel ?

Well, it has been adressed elsewhere in this forum and it must exist in some validation test cases.

However, mpi_telemac.conf is an USER file, wrapped by TELEMAC scripts to create the "machinefile" (named mpirun.txt in TELEMAC) for MPI.

It looks like as follow:

Thanks,
But again... I have a problem... it's and i don't find a solution...
